>> reporter: officers shot and killed legrier, a college student home for christmas break. his mother said his behavior recently changed. they also shot and killed a neighbor by mistake, bettie jones, a mother of five, had been asked by legrier's father to keep an eye out for the arriving officers. jahmal cole was her nephew. >> a 55-year-old lady was shot down by a chicago police officer. in the climate we're in, in chicago, that's almost unbelievable. nobody should be shot down on their doorstep, but my aunt especially was not a person that deserved that. >> reporter: there have been weeks of protest over police shootings, including that of 17- year-old laquan mcdonald, who in october of last year was shot 16 times by an officer now charged

with first-degree murder. over the weekend, legrier's mother, janet cooksey, stood with others wearing anti-rahm emanuel t-shirts, calling for an investigation. >> when is the mayor going to step up? when is he going to step up? >> reporter: responding to the shooting, mayor emanuel issued a statement saying, "it is clear changes are needed to how officers respond to mental health crises." in a measure of the seriousness of the problems here, jeff, mayor rahm emanuel said today he was cutting short his family vacation trip to cuba to return to chicago. >> anna werner in chicago this evening. in the presidential campaign, a front-runner feud continues, but donald trump is not limiting his attacks to hillary clinton. major garrett has more on this. >> reporter: bill clinton is always a popular draw on the democratic campaign trail, but donald trump is warning hillary clinton to keep her husband under wraps. if hillary thinks she can unleash her husband with

terrible record of women abuse, trump said on twitter, while playing the women's card on me, she's wrong. trump raised the specter of bill clinton's previous sex scandals after hillary clinton said trump has "a penchant for sexism." today the clinton campaign announced the former president would campaign on his wife's behalf starting next week with two stops in new hampshire, the state that in 1992 famously made him -- >> the comeback kid. >> reporter: in most national polls trump either trails clinton or runs neck and neck. trump wants to move ahead and signal to gop voters he's eager to challenge the clinton brand. >> you see hillary. i mean, did you watch that? what happened to her? >> reporter: but in the republican primary, trump is facing his own incoming. today the largest newspaper in new hampshire compared him to biff tannen. >> how do you know where i live? >> reporter: the arrogant, money-grubbing bully from "the back to the future" movies. in an interview with a new hampshire tv station, trump called the publisher, "a low

life." >> the paper is failing. he's doing a terrible job. this man is absolutely terrible. >> reporter: and the clinton campaign just released a statement saying hillary clinton will not be bullied or distracted by the slings trump has thrown at her and the former president. jeff, the campaign called trump's comments demeaning, his policies destructive. >> major garrett, thank you. tonight iraqi troops are on the verge of retaking a key city from isis, a city where americans fought and died during the iraq war. david martin reports on the new battle for ramadi. >> reporter: iraqi soldiers planted their national flag atop ramadi's government center. [gunfire] breaking the death grip isis held over the city just 70 miles west of baghdad. iraqi officials declared ramadi liberated, but u.s. officials cautioned isis still holds neighborhoods in the north and east. that will have to be cleared by house-to-house fighting against snipers and booby traps.

fighting has reduced parts of the city to rubble and a return to normal life any time soon is difficult to imagine. still, taking back this city marked a major milestone for an army which last may had abandoned ramadi in the face of an assault by a much smaller number of isis fighters. it also validated the american strategy of training and equipping iraqi ground troops and backing them up with strikes from the air. a total of 630 in and around ramadi. pentagon officials said the operation was a complex one which required the iraqi army first to encircle the city and then to cross rivers where the bridges had been blown. the american strategy for dislodging isis seems to be gaining traction. but no u.s. official is willing to second the iraqi prime minister's bold claim that 2016 would see the final defeat of isis in iraq. defense secretary carter called the retaking of ramadi's

government center a significant step but added, "the fight against isis is far from over." >> david martin tonight. thousands have been forced out of their homes -- by a massive gas leak. and -- gone in an instant.

a slow motion environmental disaster in california where a torrent of methane gas is spewing into the air. thousands have been relocated. mireya villarreal is in porter ranch. >> reporter: this infrared video shows gas rolling off the top of a nearby ridge down into the community of porter ranch. it was shot by a law firm representing several home owners who are now filing lawsuits against southern california's gas utility company. matt pakucko bought his first home in the porter ranch community eight years ago because of the scenic views and his ability to work at home as a music producer. >> i can't work in here. i can't breathe in here. when the wind comes up the hill, the gas comes down here in the fireplace, i can't work. >> reporter: the leak started in october.

so far more than 6,500 families have filed for help, but only 2,200 have been relocated. the state agency that monitors air quality estimates nearly 70,000 pounds of gas is being released every hour, roughly a quarter of the methane emissions in california. so cal gas spokesman mike mizarahi. >> once the leak is stopped, we'll be able to evaluate what caused the leak, and we'll be able to evaluate how much natural gas escaped. >> reporter: to fix the problem, the gas company drilled a relief well nearby, using magnetic technology, workers have located the leaking well more than 3,000 feet below ground. now they have to drill another 5,000 feet where they'll intersect the faulty well and pump it with mud, water and cement to stop the leak. it's made pakucko so sick, he had to move out. frustrating for you? >> beyond frustrating. it's a new way of life now. we can't live in our home. how much worse does it get? >> reporter: the leak is expected to be fixed by march,

but, jeff, as a precaution, elementary students that go to two nearby schools will be relocated until that happens. >> all right, mireya, thank you very much. lots of people love their dogs, but one couple had an unusual and very expensive way to show it. that story is just ahead.

in pittsburgh today, a bridge that stood for 94 years came crashing down in seconds. it took 1,400 pounds of

explosives to turn the greenfield bridge into rubble. it will be replaced by a new bridge in the next two years. a british couple loved their dog so much they paid $100,000 to have it cloned after it died. using the dna south korean lab created two identical boxer puppies. the first one was born the day after christmas. the second is expected any day now. former outfielder dave henderson has died. he spent 14 years in the majors and is best remembered for his dramatic home run in the 1986 american league championship series. that one swing electrified the boston red sox and helped propel them to the world series. henderson died in seattle of a heart attack three months after having a kidney transplant. dave henderson was 57 years old. meadowlark lemon was a basketball legend who made everything, even half-court shots, look easy. we'll remember him next.

finally tonight, meadowlark lemon famously said it was his destiny to make people happy. that he did through 24 years and by his count 16,000 performances with the harlem globetrotters. lemon died yesterday in arizona. don dahler looks back. [harlem globetrotters theme music playing] >> reporter: during his heydey in the '70s, there was arguably no more well-known and beloved athlete in the world. he starred in commercials. >> i'm a whiz at this whopper biz. >> reporter: and on saturday morning tv.

>> that's why i am your leader. i think of those things. >> reporter: but it was on the court that the man referred to by some as "the clown prince of basketball" reigned supreme. meadowlark lemon made it look so easy, the hook shots, the no- look passes, the comic routines. the great wilt chamberlain called meadowlark "the most sensational, awesome, incredible basketball player he'd ever seen." after watching a newsreel of the globetrotters when he was 11, lemon decided that, not the nba, would be his future. during his 2003 induction into the basketball hall of fame, the wilmington, north carolina, native described the moment. >> i made my own hoop out of a coat hanger and onion sack. for my basketball i had a carnation milk can. i'd grab that and sing along and learn how to shoot a hook shot. >> reporter: the globetrotters played to larger crowds than most nba teams. they're credited with helping desegregate the sport. after leaving the globetrotters

in 1979, lemon eventually became a minister, but every day he would head to the gym to play the game he loved, the game that loved him back. >> i've had a wonderful time and the best is yet to come. >> reporter: meadowlark lemon was 83. don dahler, cbs news, new york. that is the "cbs overnight news" for this tuesday. for some of you, the news continues. for others, check back with us later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm jeff glor. -- captions by vitac -- www.vitac.com

this is the "cbs overnight news." >> welcome to the "overnight news." i'm don dahler. the iraqi military is claiming a partial victory in its battle against the islamic state. iraqi troops backed by u.s. air power managed to fight their way into the center of ramadi, a provincial capital just an hour's drive from baghdad. the city has been under isis control since may and has been under siege by iraqi forces for months. about a third of the city is still in enemy hands and the iraqis are dealing with snipers, booby traps and minefields. debora patta has the story. >> reporter: the iraqis claimed victory after pushing isis out of a key government complex, but

they are still facing pockets of resistance. iraqi troops are taking over ramadi street by street, but progress has been hampered because the area is rigged with explosives. the offensive began six days ago, and it has been a tough fight. [ gunfire ] fierce gun battles raged as iraqi soldiers pushed their way into the heart of the city. their target -- seizing back the main government compound. this is a far cry from when the iraqis suffered a humiliating defeat in ramadi. they were shown fleeing the city after isis captured it in may. it demonstrates a force capable of defeating isis on the ground, says former cia deputy director michael morrell. >> this is the first time the iraqi government has retaken territory from isis. so it's significant in terms of the iraqi government getting its act together. >> reporter: recapturing ramadi

will not only be a psychological boost for the iraqi military, the city is also in a key geographical location. ramadi lies about 60 miles west of baghdad on a strategic road that leads into syria. the government's next major target will be the northern city of mosul, the most densely populated area under isis control. ramadi really is a test case of getting back mosul. gaining control in mosul would essentially deprive isis a major sense of funding and influence. on the campaign trail, it's shaping up to be a two-horse race between hillary clinton and donald trump. a new -- trump continues to have problems with women voters. 61% have an unfavorable opinion of the gop front-runner. the battle between trump and clinton is getting personal.

major garrett reports. >> reporter: donald trump has. been seen in public for days but remains a campaign presence, continuing his feud with hillary and bill clinton while drawing economic fire from bernie sanders. >> i'm winning. i'm beating everybody. in my opinion, beating hillary is easier than beating these people. >> reporter: by that, trump means other republicans. he still hasn't one won contest, but trump is already plotting a general election run against hillary clinton. >> i'll tell you what, if you have another four years of like a hillary, that kind of mentality and thinking, we're not going to have a country left. >> reporter: after enduring criticism of sex im, trump threatened to revisit clinton sex scandals. on twitter, he alleged "he's demonstrated a pen chant for sexism, adding without a whif of irony, so inappropriate.

trump says bill's past is fair game. >> it is fair game because his presidency was considered to be very troubled, to put it mildly, because of all the things she's talking to me about. >> reporter: clinton hasn't responded to trump's broad sides. but bernie sanders accused trump of toying with frustrated voters, offering anger, vulgarity and bad policy. >> i think what trump has done successfully i would say is take that anger, take that anxiety about terrorism and say to a lot of people in this country look, the reason for our problems is because of mexicans and he says they're all criminals and rapists. >> reporter: sanders also said that donald trump is favoring lowering people's wages. on twitter, trump called that a lie. bernie sanders also said that trump favors increasing tax cuts for wealthy. trump's tax plan would provide

an average tax cut of $1.3 million a year, and a cut of $2700 to middle income learners. star quarterback peyton manning is promising a lawsuit against the al jazeera network, after it ran an investigative story alleging he used performance enhancing drugs. jericka duncan has more on the allegations and manning's angry response. >> reporter: the allegations come from a former intern at a clinic manning attended for rehab in 2011. the source has since recanted his entire story. but the five-time mvp isn't taking any chances, going on the offense and even hiring a former white house spokesman to handle the potential fall youtd. -- fallout. >> absolutely not. >> reporter: peyton manning fought back sunday, denying allegations he used human growth hormones while recovering from a neck injury in 2011. >> i busted my butt to get healthy. and this guy is insinuating i

broke nfl rules to get healthy. it's a freaking joke. >> reporter: that guy is charlie sly. he claimed to be an employer of an anti-aging clinic in indianapolis that manning attended after undergoing four surgeries, including a neck fusion that caused him to miss the entire 2011 season. >> a bunch of baseball players were taking it, too. >> reporter: in an investigation by al jazeera into the world of performance enhancing drugs and professional sports. sly claims manning and other top athletes used banned substances. >> all the time we would be sending ashley manning drugs, like a growth hormone, all the time everywhere and it would never be under peyton's name. >> reporter: the institute has denied these allegations and sly has since backtracked. >> the statements on any recordst that al jazeera plans

to air are false and incorrect. >> reporter: his account of his employment are also being questioned. he was an intern there for three months in 2013, two years after manning was a patient. manning's current and former teams are rushing to his defense. in a statement, the denver broncos say they support him 100%, while his former team, the indianapolis colts, called the claims utterly ridiculous, saying manning never took any short cuts and it would be absurd to think would have taken performance enhancing drugs. over 18 years, manning has built an incredibly valuable reputation. >> peyton manning become the nfl's all-time leader. >> reporter: shattering records and winning a super bowl ring. accusations like this could tarnish that image. >> his reputation, it means everything to him. this is the sort of thing that could put his career, just put

some questions about all the things he accomplished. the "cbs overnight news" will be right back. ah, lilly. she pretty much lives in her favorite princess dress. and she's not exactly tidy. even if she gets a stain she'll wear it for a week straight. so i use tide to get out those week old stains and downy to get it fresh and soft. and since i'm the one who has to do the laundry, i do what any expert dad would do. i let her play sheriff. i got 20 minutes to life. you are free to go.

for years, james whitey bulger was the most notorious mobster in boston. then with the fbi on his trail, he and his long-time girlfriend just disappeared. they eluded the law for 14 years by hiding in plain sight in santa monica, california. they were pretending to be a husband and wife couple. steve kroft spoke to their neighbors and the agents who caught them for "60 minutes." >> reporter: if you're forced into retirement with a desire to be left completely alone, there is no better place than santa monica, california. this suburb of l.a. is shared by transients, tourists, celebrities and lots of senior

citizens. attracted to the climate, and an abundance of inexpensive, rent controlled apartments. places like this on third street, which is where charlie and carol gasco, a childless couple from chicago, lived for 14 years, without attracting much attention from long-time neighbors or landlords. josh bond is the building manager. what were they like? >> they were like the nice, retired old couple that lived in the apartment next to me. >> reporter: good tenants? >> excellent. never complained, always paid rent on time. >> they had nothing. and they never went out. they never had food delivered. she never dressed nicely. >> you thought they were snoor >> yes, without a doubt? >> reporter: the one thing that everybody remembers is they loved animals. barbara remembers that carol always fed a stray cat after its

owner had died. >> she would, you know, pet it and be sweet to it. and then they would put a plate of food like out here. >> reporter: what about charlie? >> you know, he always had a hat on and dark glasses. i have to say, it was mysterious to me why a lovely woman like that was hanging out with that guy. that old, grumpy man. i never could figure that one out. until i heard they had $800,000 in the wall. and then i went oh, okay. >> reporter: money wasn't the only thing found in the apartment on june 22, 2011. when the fbi stopped by and ended what it called the most extensive manhunt in the bureau's history. >> weapons all over the apartment, shotguns, mini rugers, rifles. >> reporter: what started out as

a routine day for special agent gariola, would turn into one of the most interesting days of his career. after getting a call to stake out a building in santa monica, he notified his backup team with the lapd. >> i had four guys working that day. i said we got a tip on whitey bulger, i'll see you there in about an hour. invariably, texts were returned, who's whitey bulger? i had to gently remind him who he was. >> reporter: that he was number one on the fbi's most wanted list. >> big east coast figure, but the west coast, not so much. >> reporter: but then few mobsters have ever been as infamous in the city as whitey bulger was in boston. and his reputation was for more than just being grumpy. besides extortion and flooding the city with cocaine, he

routinely performed or ordered executions. some at close range, some with a hail of bullets. and at least one by strangulation, after which it's said he took a nap. the special agent who ran the whitey bulger task force had heard it all. >> bulger was charged with 19 counts of murder. he was charged with other crimes. he was a scourge to the society in south boston. >> reporter: he was also a scourge to the fbi and a great source of embarrassment to the fbi task force. years earlier, he had infiltrated the boston office of the fbi, and bought off agents who protected him and supplied him with information, including the tip that allowed bulger to flee just before he was indicted. >> we had to catch this guy, and it was just a matter of bringing this guy back to boston.

>> reporter: they joined the task force in 2009. the joke was, bulger was on the fbi's least wanted list. there hadn't been a credible lead in more than a decade, and their efforts in bulger's old neighborhood in south boston were met with mistrust and ridicule. >> some people told us you respect looking for that guy. people made the assumption that we had him stashed somewhere. >> despite that mindset we're not going to help you, the fbi still got it done. >> reporter: it took 16 years. >> it took 16 years. this was not a typical fugitive. >> reporter: the fbi said bulger planned his getaway years in advance, with a fake identity for a thomas baxter. during his first two years on the lam, bulger was in touch with friends and family, shuttling between new york, chicago, and the resort town of grand isle, louisiana, where he rented a home until his identity was compromised. after that, it seemed as if he

had disappeared from the case of the earth, except for the alleged sightings all over the world. how many of these tips do you think might have been true? >> there are thousands and thousands of tips and i don't think any of them were true. >> reporter: one of the obstacles is there were no good photographs of bulger or his long-time live-in girlfriend, catherine gregg. the fbi noted that they shared a love of animals, especially dogs and cats, and asked veterinarians to be on the lookout. there were reports that gregg once had breast implants in boston, so the task force reached out to physicians. eventually they got a call from a dr. donally, who located her files in storage. >> i was trying to leave the office early to catch one of my kid's ball games. i said listen, i'm going to swing by in the morning and pick those up. they said, do you want the

photos, too? i said do you have photos? i said, we'll be there in 15 minutes. >> the breast implant lead produced a treasure trove of catherine gregg photographs to help crack the case. the fbi decided to switch strategies, going after the girlfriend in order to catch the gangster. >> this is an announcement by the fbi. >> reporter: the fbi created this public service announcement. >> 60-year-old greig is the girlfriend of 81-year-old bulger. >> reporter: it ran in 14 markets aimed at women. >> call the tipline. >> reporter: and it didn't take long. the very next morning, the bulger task force got three messages from someone that used to live in santa monica, and was 100% certain that charlie and carol gasgo, apartment 303, were the people they were looking for. the descriptions and the age difference matched, and u.s. marshal neil sullivan, who handled the lead, said there was

another piece of tantalizing information. >> the tipster described that they were caring for this cat and their love for this cat. so that was just one piece of the puzzle and the tip that just added up to saying, if this isn't them, it's something we better check on immediately, because it sure sounds like them. >> reporter: the search of the fbi's computer database raised another red flag. not for what it found but for what it didn't. >> basically, like they were ghosts. no driver's license, no california i.d. like they didn't exist. >> reporter: that's the apartment? >> that corner on the third floor. >> reporter: on the right hand side? >> yep. >> reporter: by early afternoon, the fbi had set up a number of surveillance posts and had already met with the apartment manager to talk about the tenants. >> he closed the door, threw down a folder, opened it up and said are these the people that live in apartment 303? >> reporter: did you say anything? >> my reaction was holy

[ bleep ]. i still didn't really know who he was. >> reporter: but it didn't take long to figure it out. while the fbi was mulling his options, bond logged on to the wikipedia page. >> i'm like wow, this guy is serious. murder, extortion. then i get to the bottom and there's this thing from one of his old people saying, the last time i saw him he said when he goes out, he's going to have guns and be ready to take people with him. i thought maybe i shouldn't be involved in this. >> reporter: bond told the fbi he wasn't going to knock on the door because there was a note posted expressly asking people not to bother them. carol told neighbors charlie was showing signs of dmementidement. >> it had the game gasco across it. >> reporter: he had the manager call to say their locker room

was broken into. carol said her husband would be right down. >> guns out, fbi, don't move. fbi, get your hands up, hands went up right away. and then at that moment we told him to get on his knees and he gave us, yeah, he gave us i ain't getting down on my "f"-ing knees. didn't want to get his knees dirty, wearing white pants. >> reporter: even at 81, this was a man used to being in control. >> i asked him to identify himself. that didn't go overwhelm. he didn't me to "f"-ing identify myself. i said are you whitey bulger? he said yes. >> you can see the full report on our website, cbsnews.com. the "overnight news" will be right back.

more than half a million of them actually. soldiers from ft. hood anxiously heading off to war and some with the deepest relief imaginable coming home. >> she meant a lot to a lot of us and had a wonderful, wonderful impact on everybody that she met. >> reporter: last month when word got out that elizabeth was losing her long battle with breast cancer, the troops made it their mission to return the hugs, and to thank the 83-year-old air force veteran for her service. former president george w. bush sent her a letter. >> thank you for all you have done. >> reporter: last tuesday, elizabeth was honored with a big award for her devotion to the troops. two days later, on christmas eve, she passed away. >> she was a smiling face, you know, in a time where people

the hoverboard was one of the most popular gifts this holiday season, despite stories of them catching fire and being banned from airplanes. but it turns out one of the most dangerous things a kid can do with a hoverboard is left their parents ride it. ben tracy reports. >> this is a piece of cake. >> reporter: it's the gift that keeps on giving, especially for kids enjoying seeing their parents hop on their hoverboards and finding themselves cruising for a bruising. in social media videos, helmets and knee pads are nowhere in sight. so when many parents go down, it does not end well. this teenager tweeted, my

spraped his arm riding my hoverboard. merry christmas. and hoverboards is for kids. my daughter got it. i ended up in the er. most adults are finding the thrills are not worth it. baseball free agent dan uggla tried to roll with his kids, but had a hard time getting into the swing of things. that's just one reason the #hoverboardfails has gone viral. just before christmas, the u.s. consumer product safety reported the number of injuries associated with hoverboards spiked 35%. that is expected to rise dramatically in the post holiday tally, and worries some safety experts. >> you have a product that doesn't have to meet any safety requirements. >> reporter: nathan furnace sells the boards in los angeles. he thinks the problem is overconfident adults who don't realize the boards are

self-balancing scooters. >> they think i got this, and they're trying to balance themselves up. stop, chill out. just stand straight up. >> reporter: he showed me the proper way to board the board. >> try to stand straight up. >> reporter: i thought i got the hang of it quickly, until i didn't. have you seen a lot of adults wipe out on these things? >> i have to be honest, yes. my mom, in fact, was one of the adults that wiped out on them. >> reporter: and that may be the lesson of this holiday season. something that seems like child's play is probably best left to actual children. for "cbs this morning," ben tracy, on the pavement of a los angeles parking lot. and that's the "overnight news" for this tuesday. for some of you, the news continues. for others, check back with us a little later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm don dahler.

it's tuesday, december 29ing, 2015. this is the "cbs morning news." a massive storm system, including snow and ice, heads east. but more flooding is forecast for the mid-west and the severe weather that's causing major travel delays. cleveland officials are calling for calm after a grand jury voted not to indict the police officer who shot and killed 12-year-old tamir rice. and the affluenza defense. the texas teenager who skipped out while serving probation for killing four people in a drunken
