i'm randi kaye. be sure to tune into cnn's film "documented," tonight at 9:00 eastern time. but first, a cnn special report, "downward spiral inside the case of aaron hernandez. that begins right now." thanks for joining me. he was the all-american destined to be an all-pro. >> he was projected to be one of the best tight ends of his generation. >> instead, aaron hernandez is an accused killer, first one murder charge. >> get the question all the time, do you think your boy did it? no, i don't want him to have done it, no. >> then -- >> aaron hernandez fired a .38-caliber revolver multiple times. >> two more charges of murder.

>> it was a brutal double-homicide. >> how in the world did he get here? >> i think if he had had someone at 16 when his dad died that could have guided him, he may have gone in a different direction. >> and how much further could he fall? tonight, "downward spiral: inside the case against aaron hernandez." it's a springtime saturday in new england patriot country, a perfect day for football. >> you wake up. >> one, two, three, hard work! >> mike branch coaches the boston bandits, a semi pro team. he remembers another day just like this, june 15th, 2013. something seemed out of place. >> a black suburban pulls, like, right up on my car.

i'm like, "who is pulling in front of my car"? >> in the driver's seat, bandit defensive end, 27-year-old, oden lloyd. >> then i see a smile. >> branch thinks it's odd because lloyd doesn't own a car. >> i'm like whose car is this? >> branch has suspicions, but never gets a straight answer. lloyd is busy telling his buddies about the good time he had at a club the night before. >> oh, he said he was at the club with mr. hernandez and that they were partying and he had a good time and that mr. hernandez spent a good amount of money. >> mr. hernandez is aaron hernandez, a $40 million rising star with the new england patriots. how much money? >> he said like 10 grand. >> 10 grand? in one night? >> that's what he said, yeah. >> when the club closes, the evening continues at an apartment the football player keeps near the patriots' stadium. oden lloyd's best buddies,

darrell hodge and darrell sweet, say their friend wasn't normally a big partier. they know a different side of him. the friend they describe was passionate about football. >> whistle blows. he's coming full throttle. >> and family. >> definitely always took care of his moms and sisters. >> my brother and i were kind of like -- i wouldn't say best friends, but, you know, as close as siblings can get. >> in and outs. >> branch, who also coached lloyd in high school, didn't hesitate to give him advice as an adult, and an occasional reality check. >> at some point, we realized we're not going to the nfl, this is just going to be for fun. what i got to do to prepare myself for life? >> he says lloyd was doing landscaping while figuring out what next. >> i spoke to him about, you know, taking firefighter tests.

>> lloyd also began dating college student shayanna jenkins. she's the link between the young man who dreamed of the nfl and the all-american who made it. what's your understanding of how they met? >> they're dating sisters. >> shaneah is the younger sister of shayanna, who is engaged to hernandez and mother of his little girl. >> 13 years. >> former patriots running back kevin faulk is a friend of hernandez. he played with him for two and a half seasons. >> tight end in a receiver body that could play running back that could return punts, return kicks. >> but how close were the talented tight end and the struggling landscaper? how much do you know that they hung out together? >> really? just two different worlds. but he had one world, we got our world.

>> you should check out my new camera. >> on sunday, june 16th, father's day 2013, odin lloyd is cruising with his friends in that mysterious black suburban. >> we had the music playing, jamming to the music and stuff, laughing and talking and odin driving, got the one-hand-type driving, like he's just having fun. later, we went to my aunt's house and was playing pool. >> move the table. move the ball. >> i seen odin make one of the most spectacular shots i've ever seen. >> no chance in hell. >> it was a good day?

>> it was a great day. >> you got that? i hope y'all got that. >> a great day. >> and it was coming to an end after lloyd got a text from his job saying he had to work the next morning. >> then he got another text asking to hang out. >> a text from hernandez. >> he had a text to let's have another great night. >> i take it there was a part of, man, you got to go to work the next day. >> go home. yeah, it's already like 9:00, 9:00ish. >> when you guys left each other, what do you remember saying to him? >> i'm going to see you later. >> little did he know, there would be no later. monday, june 17th, 5:37 p.m., lloyd's body is discovered by a jogger in north attleboro, 35 miles south of where he lives. here at the crime scene, investigators find his wallet, driver's license and five .45-caliber shell casings. they suspect he was first shot in the back and finished off as he was laying face up in this secluded area of an industrial park. darrell hodge learns of the murder from lloyd's sister,

olivia, who calls him. >> i could hear her. >> did she say "he's dead"? >> in between the cries and the bawling, "darrell, odin is dead. olivia, i'll be there in a minute." i got to the house. i got inside. like -- >> and you saw his mom? did she say? >> "darrell, who killed my son?" do you say to that? i immediately fell to my knees, gave her a hug, wrapped my head around her hip, and, like, "mom, i don't know." >> that night was tough for darrell sweet who was also at lloyd's home. >> i just went back and sat in my car. >> what were the questions in your head? >> who was he with? didn't know who he possibly could have been with until i got the news of the text.

>> shaquilla is lloyd's youngest sister. she sees him picked up from their house and driven away in the middle of the night. just before lloyd dies, police say he sends shakeela chilling text messages. at 3:07 a.m., lloyd asks, "you saw who i'm with?" at 3:11 he texts again, "hello." 3:19, shaquilla answers, "my phone was dead, who was that?"

3: 22 a.m., lloyd answers "nfl." and a minute later, at 3:22 a.m., lloyd sends his very last text. "just so you know." was he trying to leave a clue he was with hernandez? >> odin crazy and o don't work in like mysterious ways, only god do that. if he left him crumbs, something was going down. >> but what was going down? and why? okay, listen up! i'm re-workin' the menu.

for daryl hodge, going to the gym means lifting weights, but he's also carrying one, trying to understand why someone killed his best friend, odin lloyd.

>> i would be still lifting with my bro. we would be trying to dunk. >> after a jogger finds odin lloyd's bullet-riddled body, police quickly find their first pieces of evidence, distinctive tire tracks, lloyd's cell phone and keys for that black suburban he had been driving all weekend. police quickly learn it was rented by new england patriot, aaron hernandez. over the next several days, investigators search his home and cars, removing bags of possible evidence, including hernandez's cell phone, but a law enforcement source says it's badly cracked, possibly intentionally, before it was handed over. june 26th, 2013, nine days after the murder of odin lloyd, hernandez is arrested.

the charges, first-degree premeditated murder and having illegal weapons. his plea? >> not guilty. >> and he's no longer a new england patriot. >> i and other members of the organization were shocked and disappointed. >> hernandez is canned before he reaches the courthouse. >> mr. hernandez is charged with a very serious crime, but that shouldn't be enough to hold him without bail. >> and he's staying in jail. his attempts at bail denied. >> i think the commonwealth presented a case that's circumstantial to be sure, but very, very strong. >> hours after his arrest, the public hears those details for the first time. 9:02 p.m. father's day, june 16th. >> the defendant had sent a text message to a friend of his who

was out of state, "please make it back." >> that friend is ernest wallace in bristol, connecticut, more than 100 miles away. at 9:35, hernandez texts him again, "get your ass up here." wallace is joined by carlos ortiz. both have criminal records. at about the same time, hernandez is also texting lloyd. "i'm coming to grab that tonight. you going to be around? i need that and we can step for a little again." when lloyd doesn't answer immediately, hernandez sends another text at 9:34. "what up?" lloyd answers at 9:37, "all right, where"? at 9:39, hernandez replies, "i don't know, it don't matter, but i'm going to hit you when i'm that way." after midnight, surveillance stills released by authorities

show wallace and ortiz arriving at hernandez's home. outside, the football player is holding what appears to be a gun and he's not happy. >> he makes a statement that he's upset, that he can't trust anyone anymore. the three of them departed the defendant's home at 1:12 in the morning in the silver nissan altima. >> 3:10 a.m., he's on camera at this gas station. >> the defendant bought gas, bought two other items, bubbilicious blue cotton candy gum and rolling papers for marijuana. >> at 2:32 a.m., a camera captures the same altima pulling up to lloyd's home. lloyd gets inside. as they start driving, a sign of trouble. hernandez tells lloyd he doesn't trust him, angry about who he was talking to at the club where they partied friday night.

how do investigators know about the conversation in the car? ortiz, sources say, squeals during questioning. at 3:22 a.m., a string of security cameras at an industrial park pick up the altima as it is headed toward a secluded area. >> it's 3:23 and odin lloyd sends his sister the final text, tell her he's with nfl, adding "just so you know." between 3:23 and 3:27, workers nearby tell police they hear gunshots. hernandez's home is only a half mile from the murder scene. at 3:29, a camera shows an altima pulling up in hernandez's driveway. only three people get out. odin lloyd isn't one of them. >> the defendant goes walking towards the house. >> back inside the house, images

show wallace, then again with ortiz in a basement doorway, with hernandez nearby and this, hernandez wearing white with a gun in his left hand. police, a law enforcement source says, believe this is the murder weapon, a .45-caliber gun. it remains missing. >> they all then go down to the basement. once in the basement, the surveillance gets shut off. >> around 5:30 that evening, prosecutors say hernandez and his two friends show up here to return their rented nissan altima. the manager tells investigators hernandez offers her blue bubble gum. it's the same kind he bought at that gas station, and now it's showing up in the returned rental, along with a .45-caliber bullet casing.

the manager tosses the gum and bullet casing in a dumpster. police say the shell came from the same gun that fired the rounds at the murder scene. and they say tire impressions taken near the body match the kind of tires on the altima. hernandez's attorneys won't comment on the case, and all parties are muzzled by a gag order. for family and friends of odin lloyd, knowing some details helps, but they don't answer this question. >> why? that's the biggest question. why? don't just visit rome.

as aaron hernandez adjusts to life behind bars, charged with murder, yet another accusation of gun violence makes headlines. four months before odin lloyd is gunned down, the football player is at tootsie's strip club in miami. a law enforcement source says hernandez drops about 10 grand that night. one of the men he's with, alexander bradley. prosecutors describe him as hernandez's former right-hand man. by morning, bradley is shot in the face, dumped out of a vehicle, and left for dead.

still wearing his now-blood-soaked vip wristband from the club. it happened here, an industrial park 65 miles north of tootsie's strip club in miami. it's 7:00 a.m. two men who work in that building hear a gunshot and tell police they rush outside and find the body of a bloody man lying in a fetal position just about here, according to a police report. one of the men asks the victim, "who shot you"? bradley tells them he doesn't know. police retrieve this bullet fragment from his head, but bradley won't give them any details. >> when the police investigated this incident, alexander bradley didn't put the finger at hernandez. >> that changes when bradley sues, claiming that aaron hernandez cost him his right eye. bradley later tells prosecutors he was shot after hernandez felt disrespected during an argument over a missing cell phone. after bradley is shot, prosecutors say hernandez gets a

new right-hand man, ernest wallace. >> this defendant is more commonly known by his nickname, which is hobo. >> wallace has a long criminal history. prosecutors say he sells and uses drugs, including the hallucinogen angel dust or pcp. he's not the on one. court documents show wallace's sidekick, carlos ortiz, admits he's regularly abusing pcp, alcohol and thc, pot. sources tell cnn aaron hernandez also smoked a lot of pot, one calling it a boat load. prosecutors say the tight end would give odin lloyd money to buy marijuana. cnn obtained his photograph of a

stack of blunts, said to be made of marijuana supplied by hernandez. sources tell cnn aaron hernandez also used angel dust and that could have made him paranoid. one says he felt he was a target, that people were coming after him. >> the combination of those drugs, depending on the long-term use of the drugs and the amount of drugs could cause someone to become violent, could cause someone to become very paranoid, could cause someone to overreact to a situation, appear to be more impulsive. >> that kind of behavior doesn't describe the aaron hernandez many remember growing up in bristol, connecticut, where his family was celebrated as a local sports dynasty. >> i don't think there was another family that was more familiar in bristol. aaron was our golden boy. he had the family traits, his father and uncle were standout

athletes. >> his older brother, dj, was a sports hero, too. bob montgomery covers high school sports for "the bristol press." >> aaron did track, in audition to football, he also did basketball. he was described in any sport he played as a man playing with children. >> he was just kind of goofy and fun. >> kind of had a baby face and, you know, all the teachers loved him. >> brad mcmillan and andrew rigali played basketball with aaron beginning in middle school. >> he was twice the size of me. we were the same height, but he was more athletic obviously. he practiced all the time. >> practiced because his father, dennis, pushed him constantly. >> his father was pretty strict. i mean, he told me his father used to make him shoot 500 shots before he went to play with friends. his dad clearly kept him anchored. i saw a closeness with them that i had never seen before. there was something about dennis

and aaron, the way they intertwined. it was just magic, in my eyes. >> but in a heartbeat, that closeness is gone. >> i was sitting in math class with another teammate, phone rang. teacher went to go pick up the phone. and then she said you need to go up to the coach's room. coach walks in and says, "dennis has passed away." >> dennis hernandez, aaron's father, his anchor, dies after routine hernia surgery. it hit 16-year-old aaron hard. >> he was just sad. he couldn't stop the tears. >> felt uncomfortable to see him so hurt. i felt bad for him.

>> that father/son relationship comes up in conversations with sheriff thomas hudson, who runs the jail where hernandez is being jailed. >> clearly at 16-year-old, old losing your father would be easy to follow into the lifestyle of following people that don't help you make the best choices. >> one choice he makes is to tattoo some of his dad's advice on his arms. >> this is a quote my father always used to give me, "if it is to be, it is up to me, saying whatever i want my life to be is up to me to make it out that way." >> when it comes time to his his college pick, not even his brother, dj, can get him to join where their dad played, the university of connecticut. >> at first, he wouldn't even talk to me, but there are days saying, "it's our dream to play together. come on, please." >> but aaron stands firm, believing his football career will sore in gator country. coming up, a promising college

career overshadowed by trouble off the field. [ chainsaw buzzing ]

father's school, the university of connecticut, cutting his high school senior year in half. he heads to the university of florida. >> then i was kind of just bummed that he wasn't going to be on our basketball team. >> in january 2007, he joins the gators and star quarterback, tim tebow. by april, still long before the gators season opener, there is trouble off the field. the rookie teen loses his cool at this popular off-campus restaurant. there is an argument between aaron hernandez and the manager over a bill. tim tebow tries to calm things down and settle the check, but according to this police report, it all ends with aaron hernandez sucker-punching the manager on the left side of his head, bursting an eardrum. the manager later tells police, university of florida coaches and lawyers have contacted him, and they are working on an agreement. a university spokesman says they are not aware of any settlement.

five months later, in september, there's more trouble. this time, a shooting near the university. it begins with young men snatching gold neck chains at a local club. there's an argument in the parking lot across the street. police report several uf football players are involved, including hernandez. >> i know hernandez was there. there was trouble. >> there was arguing loud. >> the suspected chain snatchers get into this man's car. his name is corey and doesn't want his face shown for fear of retribution. can you point out roughly where it was? moments after leaving the club, someone fires into corey's crown vic, hitting him in the head. >> can you tell me and show me, where is it that that bullet went? it came right about there? >> i can't imagine what he would have felt that night. >> corey's aunt stephanie remembers he nearly died.

>> his heart stopped a couple times. >> they had to take half of my skull to get the bullet out. i was in rehab and they helped me to walk again and talk again. >> police interview more than 20 people, and they try to question hernandez, but he's the only one who doesn't make a statement after invoking his right to counsel. at the time, his mother, terry hernandez, tells the "orlando sentinel," "i know he was at the club, but he never saw any shooting." it's still an open case. no one has ever been charged. both corey and his aunt stephanie have been trying to get to the truth for seven years. you've done a lot to try to get to the heart of what happened. what about going to the university of florida? >> i tried it. i was just told that they would put the guys on curfew so that

they could, i guess, lessen their activities in clubs and things of that nature. i would have like to seen some more in-depth questioning of those football players. >> citing privacy laws, the university of florida won't discuss specifics of how players are disciplined. was hernandez on a slippery slope? he was tearing up the field as a gator, but some who knew him were worried, especially when he was unsupervised away from the game. "if you could keep him on one side, he would be fine," one source put it. the problem was he couldn't stay away from the other side, adding it was a recipe for disaster. and it was a recipe that included marijuana. hernandez was suspended at least once for using the drug. it's an issue that follows him when he enters the draft his

junior year. >> teams spend a lot of money on background checks, hiring private investigators to be sure this is somebody who will enter the nfl and stay out of trouble. >> and how far back do they go? >> if you done something in middle school, they will go back and find somebody that was around that time and ask them. >> trying to head off trouble before the draft, hernandez goes on the offensive, writing a letter to the patriots' director of personnel. "if you draft me as a member of the new england patriots," he wrote, "i will willfully submit to a biweekly drug test throughout my rookie season." >> prior to the draft, aaron hernandez was a player that could be a first-round pick and no later than a second round pick. >> with another selection, they go aaron hernandez. >> he ends up the 113th pick, passed over until the fourth round. >> i have to believe that him

falling so far is more than just a story about marijuana. there were questions raised in background checks about him that caused teams to say we'll downgrade him on our draft board. >> but during his first year with the patriots, he proves himself. >> there were questions that, oh, he's too young to be in the league, he's not going to get belichick's system. he was able to debunk those by having a solid season. >> by the end of his second season, hernandez has star power, inking a five-year, $40 million extension. >> you can't come here and act reckless and do your own stuff. i might have acted the way i wanted to act, but you get changed by bill belichick's way. >> what no one knew at the time, one month before he signs that deal, the football player parties at a boston club. that night, two young men are shot and killed after leaving that same club by a man driving a silver suv. is there a connection? okay, listen up! i'm re-workin' the menu.

it's a silver suv, but in the life of aaron hernandez, it's much more. while searching his cousin's home for clues in odin lloyd's murder, police stumble on a toyota 4runner. it's in a garage and it belongs to a leasing company who loaned it to the patriot tight end in exchange for promotional work. for the past year, boston police have been looking for an suv linked to an unsolved double-murder. this appears to be it. how difficult has this loss been for you, sir, as a father? ernesto abreu's son, daniel, was killed in the drive-by shooting

outside a boston nightclub with his friend, safiro furtado, on july 16th, 2012. witnesses say two men in a silver suv with rhode island plates pulls alongside abreu's car, shots are fired. what do you miss the most about him? >> translator: we would hang out like brothers, abreu's father tells me. abreu's father was a police officer in cape verde and wanted to do the same work in the u.s. he spoke three languages and worked as a tour guide in cape verde. safiro furtado he had only been in the u.s. for six months. how much do you miss him? losing a son, his father says, is like losing a hand. two grieving fathers searching

for answers. finding that suv and other tips leads to a stunning discovery. aaron hernandez seen on security video, police say, with another man, following abreu and furtado into that nightclub and stalking them in a silver suv after they leave. almost a year after he's charged with odin lloyd's murder -- >> aaron hernandez, please rise. >> -- aaron hernandez is indicted for the murders of those two young men. >> how do you plead to this indictment? >> not guilty. >> the defendant leaned out of the driver's side window of the suv with a loaded revolver in his hand, extended out. the defendant immediately fired at least five rounds fr from .38-caliber revolver into the victims' car. >> but why? >> daniel abreu, while dancing nearby, accidentally bumped into

the defendant, causing the defendant's drink to partially spill. >> the motive, prosecutors say, is nothing more than a spilled drink by a complete stranger. >> the defendant told his friend that abrau had deliberately bumped him and was "trying him." >> court documents identify the friend with hernandez that night as alexander bradley, the same alexander bradley who says hernandez later shot out his right eye because the football player felt disrespected during an argument over a cell phone. all leading to a key question, do those two violent acts suggest a dangerous pattern of behavior driven by paranoia? cnn has learned prosecutors believe that behavior is what led to odin lloyd's murder. a source with knowledge of the investigation says the night

they were at this club, hernandez gets angry when he sees lloyd talking with two men. and angry again later at hernandez's apartment when lloyd gets a look at guns and ammo kept there. it's unclear exactly what ticks him off that night. the source will only say it's as trivial as that spilled drink allegedly behind the double-murder. >> motive does not have to be proven under the law. >> jared leone is both a former massachusetts district attorney and federal prosecutor. >> juries like motive. juries want to know why someone did something, especially when they have done something alleged to be as heinous as this was. >> a motive, no matter how trivial, would make the state's case stronger. prosecutors have already bolstered the case by upgrading the charges against co-defendants ortiz and wallace to murder. >> how do you plead? >> not guilty. >> not guilty. >> charging of carlos ortiz and ernest wallace for murder really

signals that this will be a joint venture murder prosecution, where anyone who actively participates in the murder can be held guilty for the murder. >> that would mean hernandez could be convicted of murder, even if prosecutors can't prove he fired the gun. but none of this makes the case rock solid. it still has holes. >> there remains no murder weapon. >> conviction without a gun is more difficult. still ahead, even a jail cell can't keep aaron hernandez from getting into more trouble.

for odin lloyd's mother, ursula ward, every day is a struggle. >> hey, handsome. mommy is here to see you again. i love you. i miss you so much, sweetie. i never thought i would be talking to my son in the ground, you know. >> at every pretrial hearing,

she is surrounded by family, hangs on every word. >> mr. hernandez's right to fair trial. >> but the justice she seeks is still a long way off. a trial date is pencilled in for october, but it might start much later. >> one plausible timetable is that the aaron hernandez case for the murder of odin lloyd goes to trial some time in the summer or spring of 2015. >> the fallen football star spends his days waiting alone in a 7 x 10 foot cell. trying to keep him in line is sheriff thomas hodgeson. >> i've talked to him at length there is a warmth within this person. >> what went wrong? >> learned behaviors and the environment that people grow up in have an incredible influence on who we become. >> sheriff thomas hodgson believes in modifying behavior behind bars.

he says inmate number 174954 is reading the bible. and another book he suggested. >> i got him reading "tuesdays with morrie." >> it examines how to create a centered, meaningful life. >> he was clearly moved by the book. he called his mother and told her she needs to read it. >> the sheriff tells hernandez to find his center by turning to his childhood anchor, his late dad. >> you will never be able to get back to that place you felt comfortable and safe and that's only going to happen if you go back, talk to your father. go back to your cell and talk to your father. >> what did he think about that advice? >> when i see him every so often, hey, did you do what i asked you? no, but i'm getting there. i think at this point he's got a picture that he didn't have before, his dad's picture. >> a photograph of his late father in his cell. >> it's not as bad now that i'm not playing.

>> retired patriot running back kevin faulk hasn't given up on his ex-teammate. >> i want to tell him he has somebody on his side that is praying for him. >> prosecutors are saying that he orchestrated the execution of someone. >> you're not going to make me believe that he is a monster because you used those type of words. >> not even two more murder charges in the so-called spilled drink case have changed faulk's opinion of the player he knew. >> i get the question all the time. you think your boy did it? no, i don't want him to have done it, no. so if you want me to say no, no, i don't think he did. at the same time, anybody can be pushed to do something drastic like that, if they push you to that point. >> even behind bars, trouble continues to follow faulk's former teammate. after trash talk with another inmate, that man's lawyer says hernandez got some punches in.

it got physical, didn't it? >> no question it was a physical altercation, absolutely. >> hernandez is now charged with assault in that fight. that's on top of the three murder charges, a lawsuit claiming hernandez shot a friend in the face, three civil suits from the families of his alleged victims, and according to sources, a federal gun trafficking investigation. as for the odin lloyd case -- >> i think the odds are likely that aaron hernandez will be convicted. do i believe that it's a slam-dunk? no. >> the ex-patriots lawyers contend the circumstantial evidence so far is full of gaps. >> there is certainly a lot of what i would call smoke. there's no doubt about it. but that's not probable cause that he committed murder. and you can't just throw a bunch of stuff against the wall and say that's good enough. >> all rise.

>> hernandez's lawyers and mother declined our request for an interview, but predict he'll be cleared. >> we're confident that aaron is going to be exonerated, and that when witnesses have to testify, that a jury of aaron's peers will find that he is not guilty, and in fact had no part in the killing of odin lloyd. >> however, an interesting twist mid-june. hernandez's lawyers asked a judge to issue a subpoena for the new england patriots. the defense wants medical records that quote, may bear upon hernandez's mental state at the time of lloyd's murder. it's an indication his attorneys may be considering what is called a diminished capacity defense, arguing hernandez is less capable of knowing right from wrong. >> eternal rest grant unto him.

>> days after what would have been odin lloyd's 28th birthday, family and friends come together for the unveiling of number 53's headstone. >> i don't know if anything can really heal me right now. he was the love of my life. >> in loving memory of odin lloyd, our son or brother, amen. >> and you still talk to him? >> yeah. >> what do you say? >> i miss him. i love him, miss him. >> no matter what the outcome is, we still lose at the end of the day, even if you get justice. do you really come out a winner? i don't think so. >> do you think there is a chance that aaron hernandez may be found not guilty? >> that's my biggest fear. because all it takes is one juror. >> we love you, odin.

mexico is a country where every day people fight to live. all too often, they lose that battle. a magnificent, heartbreakingly beautiful country, the music and food, and a uniquely mexican, darkly funny, deeply felt world view.
