>> axelrod: good evening. i'm jim axelrod, and this is a western edition of the broadcast. he was public enemy number one, a modern-day al capone in the eyes of law enforcement in chicago. we're talking about a brutal mexican drug lord named joaquin guzman, known as "el chapo," or shorty. tonight, he is in a prison in mexico city. captured in a joint u.s. and mexican operation. the feds says guzman ran an international heroin and cocaine empire worth $1 billion. employing thousands of gang members in chicago to deal drugs. as carter evans tells us, his arrest ends a 13-year-long manhunt. >> reporter: shackled and surrounded, mexican authorities paraded the world's most notorious drug lord before news cameras. joaquin "el chapo" guzman was captured in a dramatic covert operation, led by the mexican navy early this morning, in the resort town of mazatlan. we arrested him without firing a

single shot, says mexico's attorney general. guzman is known as "el chapo" or shorty because of his small stature, but there is nothing small about the global reach of his multibillion-dollar sinaloa drug cartel. >> this is absolutely enormous. it took my breath away, literally i did not know how to react, i was that shocked about it. >> reporter: duncan wood is an expert on u.s. mexico relations with the wilson center. >> it's a game changer, i would say, in the fight against organized crime in mexico. >> reporter: guzman had been on the run for more than a decade ever since he escaped from a maximum security prison in mexico in 2001. in that time, he expanded the sinaloa cartel into a global empire of violent drug traffickers that led right to the streets of nearly every major city in the u.s. >> we don't know exactly what the impact is going to be on the organization itself because there are, obviously, lieutenants in place that are ready to take over. >> reporter: when authorities stormed his hideout on saturday, a law enforcement source tells cbs news the cartel kingpin was caught by surprise, naked in bed with an ak-47 by his side.

in the u.s., guzman faced multiple federal drug trafficking indictments. his cartel is believed to be responsible for 70% of the illegal drugs that entered the u.s. through mexico. last year, the city of chicago branded guzman as public enemy number one. the last criminal who held that title was al capone. carter evans, cbs news, los angeles. >> axelrod: as carter just noted, guzman is under indictment in several american cities. the head of the d.e.a. in chicago says he'll push for the trial there. dean reynolds joins us now from chicago. dean, why do they want him so badly in chicago? >> reporter: because it appears, jim, that chicago was chapo guzman's favorite town. it was the place that he located his headquarters for the transshipments of the drugs to chicago, and then to 1,000 communities nationwide and in canada. this is also the place where his organization may well have had the most violent impact, and this is where two of his

lieutenants in this area were arrested in the last few years and may well have turned state evidence against him. so this would argue for chicago being the place to prosecute him. >> axelrod: dean, chicago has had so much gang-on-gang crime. if guzman is taken out of commission, what kind of effect will that have on the crime rate there? >> reporter: there are very little expectations this will have a major impact on the crime wave in the city. the police, of course, have reduced the crime substantially, but these organizations, these cartels, are like whack-a-moles, where one guy gets taken away and another guy pops up. on the street, the organization's blueprint is in place. the foot soldiers are there, so we don't expect a major change in chicago as it relates to the gang-on-gang violence. >> axelrod: dean reynolds in chicago. dean, thank you very much. in a remarkable day of upheaval

in ukraine, the parliament voted to remove president viktor yanukovich from office. yanukovich had already fled kiev for the eastern part of the country, where he has more support. also today, former prime minister yulia tymoshenko was freed after more than two years in prison, and tonight she spoke to the thousands of protesters who now control the streets of kiev. holly williams takes us through this day filled with twists and turns. >> reporter: the protesters looked ready for battle this morning, equipped with improvised weapons and home made body armor. they gathered to pray on kiev's independence square, which they've occupied since november. some wept for the scores of people who have lost their lives in this bloody power struggle. but then the demonstrators discovered there was no one left to fight. the lines of riot police had melted away in the night. they took over the grounds of the luxurious presidential palace, which had been

abandoned. it all happened so quickly that protesters like pablo gladkiydidn't know what to think. where has the president gone? >> i don't know. >> reporter: do you think he's left the country? >> i... i will be happy. >> reporter: the protesters are in control of the center of kiev. we haven't seen police anywhere today, and they've even encircled this building, the presidential administration. an aide to ukraine's president, viktor yanukovich, said he'd left kiev and gone home to his power base in the eastern city of kharkiv. back in independence square, they could sense victory. for three months, they've demanded that president leave office. they accuse yanukovich of being

corrupt and increasingly dictatorial. in ukraine's parliament, they were celebrating, too, after voting to sack the president and hold new elections in may. but when yanukovich himself finally appeared on television, he said he was still in charge and compared the protesters to nazis. both the interior ministry, which controls the police, as well as senior military figures, have come out in support of the protesters. so, at this point, jim, viktor yanukovich doesn't have many cards left to play. >> axelrod: holly williams reporting for us tonight from independence square in kiev. thank you, holly. the russian foreign minister has told secretary of state kerry that the peace deal in ukraine has been "seriously degraded" by the opposition. our state department correspondent margaret brennan joins us now from washington. margaret, the u.s. is in a delicate position without a lot of leverage, so how does the administration proceed? >> reporter: well, the u.s. already thought this peace deal was very, very fragile, and they're seeing events on the ground move faster than they expected. right now, nobody is clearly in charge of a country that is on the brink of financial implosion. so, the u.s. and europeans are

working behind the scenes to try to help get the opposition leaders, who are all jostling for influence to form a new government that can get some much-needed lopes from the i.m.f. they hope it will bring them closer to europe. but russia still has a lot of influence here regardless of who is in charge because they have a tremendous amount of trade across their shared border, and a lot of ukrainians who live in that area are still sympathetic to moscow. so the u.s. is concerned a power vacuum could lead to a split, even a civil war, and they want ukraine to stay unified. so, right now, the administration is publicly calling on everyone to try to de-escalate tensions. >> axelrod: margaret brennan in our washington bureau tonight, margaret, thank you. now to indianapolis, where the national football league is holding the annual scouting combine. that's where the nation's top college players get looked over by teams deciding on who to draft. one player is getting a different kind of scrutiny than ever seen before at the combine. terrell brown reports on michael sam, who would be the first openly gay player in the n.f.l. >> reporter: at the combine in

indianapolis, college players are showing off their skills for a shot at a career in the n.f.l., but there's one player yet to take the field who is getting much more attention than all the others. >> good afternoon. my name is michael sam. >> reporter: surrounded by hundreds of reporters, michael sam gave his first press conference since announcing he was gay. >> i just wish you guys will see me as michael sam the football player instead of michael sam the gay football player. >> reporter: the former university of missouri defensive end sported a rainbow "stand with sam" on his combine gear and was asked whether he thought being gay would hurt his chances of getting into n.f.l. >> i am not a g.m., i do not have control over my job status, all i can control is me preparing myself to get the best scores out there. >> reporter: but if he does get drafted, sam said he isn't worried about how he will be treated. >> i've been in locker rooms where all kinds of slurs were said, you know, and i don't think anybody means it. i think a little naive and uneducated, but you know, as

time goes on, everyone will adapt. >> reporter: last week on "face the nation," n.f.l. wide receiver d'onte stallworth said the league should be ready to accept michael sam. >> it's no longer a question for the n.f.l., if the n.f.l. is ready for a gay player. the n.f.l. has to be ready, and the onus is on everyone to make sure that he is in a safe workplace. >> reporter: sam is projected as a mid-round pick in the may draft. he starts his n.f.l. combine drills tomorrow. terrell brown, cbs news, new york. >> axelrod: at the vatican, pope francis welcomed 19 new cardinals today at a ceremony known as a consistory. as alan pizzey tells us, an event shaping the future of the church, began with a nod to its recent past. >> reporter: the whole spectacle of the consistory took second place to a single moment, pope francis greeting his predecessor pope emeritus benedict xvi. it was the first time a reigning, a past and potential

future pope were in st. peter's basilica together. the cardinal's principal job is to elect a new pope from among their number. as he bestowed 19 prelates with the red silk biretta that marks them as princes of the church. pope francis recited a ritual injunction, act with courage. ♪ traditionally, the college of cardinals has been packed with people from the developed world. this time, there were four latin americans, two asians and two africans. new cardinals are appointed to replace those who turn 80 and become ineligible to elect a new pope. if francis remains in office for another five years, he will have named as many as half of those who will choose his successor. he'll need that time to make serious changes in the view of the john thavis, author of the bestselling insider book "the vatican diaries." >> i go around the world and everyone is singing hosanases about pope franis and i come to rome and what you hear from the roam an curry, is a slightly

less enthusiastic tone. >> reporter: pope francis' message to the new cardinals was perhaps aimed at the curia, the church hierarchy. "whenever a worldly mentality predominates," he said, "the result is rivalry, jealousy, factions." ♪ such feelings are clearly not something from which francis suffers. alan pizzey, cbs news, rome. >> axelrod: later, the conflicting accounts that blocked a medal of honor for this iraq war hero when the "cbs evening news" continues. atrial , an irregular heartbeat not caused by a heart valve problem. that puts jim at a greater risk of stroke. for years, jim's medicine tied him to a monthly trip to the clinic to get his blood tested. but now, with once-a-day xarelto jim's on the move. jim's doctor recommended xarelto. like warfarin, xarelto is proven effective to reduce afib-related stroke risk. but xarelto is the first and only once-a-day prescription blood thinner

>> reporter: in 2004, sergeant rafeal peralta's squad was clearing a house during the battle of fallujah. when insurgents opened fire, the 25-year-old was standing next to sergeant nick jones, who spoke with cbs news in 2010. >> they were just spraying and praying, trying to hit anything that came through the door, and it happened to be us standing there. >> reporter: peralta went down, turns out he was hit by friendly fire, then an insurgent tossed a grenade into the room. >> before it even came to a stop, i just saw his arm move up and he grabbed it, just scooped it underneath his body. >> reporter: peralta was killed, and it is that version of events that led to him being awarded the navy cross. but an unsuccessful request to reopen a medal of honor nomination has unearthed conflicting accounts of what happened. davey allen, another marine who served with peralta, said he recently decided to tell the truth, confirming for cbs news what he told the "washington post," that the grenade detonated near but not underneath peralta.

"it has always bugged me. i knew it's not the truth, but who wants to be the one to tell the family your son was not a hero?" george sabga is an attorney for peralta's family. >> the evidence doesn't show that. now that's what davis believes he saw. i can't dispute what he saw or believes he saw, but what i can say is the evidence shows otherwise. >> reporter: the citation for the navy cross reads, "without hesitation and with complete disregard for his own personal safety, sergeant peralta reached out and pulled the grenade to his body, absorbing the brunt of the blast and shield fellow marines only feet away." he has been denied the medal of honor, but he remains a hero to the man who says he was there when peralta died. >> he went toe to toe with the enemy and saved our lives. >> reporter: and the mother who kneels by his grave. jeff pegues, cbs news, washington.

in minnesota, which, in some parts of the state, has been cut in half in the last five years. as don dahler shows us, solving the riddle of disappearing moose starts by finding some to examine. >> reporter: the serenity of the superior national forest in northeastern minnesota is shattered by the roar of a low- flying helicopter. inside, pilot blake malo and marksman trent brown zero in on their target, a female moose and her calf. like a cowboy working a herd, malo banks the chopper to push the animals into the clear. >> there's a whole process where you try to work the animal to a certain area, kind of like cutting a horse. you kind of work the helicopter the same way to get it to an opening. >> reporter: once in the opening, malo swoops in low and brown takes his shot. this one brings the 1,000-pound

gun. habitat loss, deaths from parasite-borne diseases and wolf attacks are all part of the equation. malo and brown are considered among the best at what is a very dangerous but necessary job. >> you know, i think we take a lot of pride in just the way we handle the operations from our end, and trying to keep it safe for, you know, the animals. >> hold on! >> reporter: and trying to keep them a part of the minnesota landscape for as long as possible. don dahler, cbs news, in northern minnesota. >> axelrod: and that is the cbs evening news for tonight. later on cbs, "48 hours." for now, i'm jim axelrod in new york. and for all of us here at cbs news, thanks for joining us and good night. captioning sponsored by cbs captioned by media access group at wgbh access.wgbh.org
