>> pelley: disturbing new revelations today about how u.s. intelligence believes an ererican woman was abused by her isis captors. also tonight, a new era begins in relations with cuba, but old tensions linger. a white police officer testifies he feared for his life when he fatally shot an unarmed black man. ( gunshots ) and what steve hartman does when he's off the road. >> i mean, sometimes he's out there past dark. captioning sponsored by cbs this is the "cbs evening news" with scott pelley. >> pelley: this is our western edition. today, on what would have been kayla mueller's 27th birthday, we learn that u.s. intelligence has been told she was tortured and sexually

assaulted while in the captivity of isis, the islamic terror group whose atrocities include the beheading of three americans. mueller, a humanitarian aid worker from prescott, arizona, was captured two years ago in syria. isis claims that she was killed last february in an allied air strike. now, u.s. officials say women once held with mueller claim that she was sexually assaulted by the leader of isis himself. here's major garrett. >> reporter: kayla mueller's parents learned of the grim details in june from the f.b.i. u.s. officials said the self- proclaimed isis leader abu bakr al-baghdadi repeatedly raped mueller, an american humanitarian worker, while she was held captive by isis with at least two other sex slaves in a syrian compound. al-baghdadi visited the compound frequently and assaulted mueller during those visits, according to senior administration officials. isis claims a coalition air

strike on this compound killed mueller in february. the u.s. government said it was unlikely mueller was held there at the time. the government based its conclusions about the sexual assaults on interviews with two teenage girls who escaped isis captivity and heard directly from mueller about the abuse. corroboration also came, scott, from interrogations of the wife of a top isis figure. >> pelley: major garrett reporting from the white house tonight. major, thank you. in havana today, a symbolic milestone in relations between the united states and cuba. prcretary of state john kerry presided over the raising of the american flag at the newly reopened u.s. embassy. margaret brennan is in havana. >> ladies and gentlemen, our great seal. >> reporter: history was made before dawn when the united foates seal was hung at the embassy for the first time in 54 years. once daylight broke, three cold war-era marines, who shuttered the embassy in 1961, helped the next generation unfurl the flag.

( "star-spangled banner" playing ) james tracy, then a master gunnery sergeant, was one of those marines who helped take iswn the flag and promised one day to return. >> we're back. and we're here to stay this time, i think. so... and i'm coming back with the grandkids, going to show them where granddaddy worked one time. >> reporter: hundreds of cubans gathered to watch. this woman said she had long dreamed of the day when cuba and the u.s. would get along. but despite the optimism of the day, there is still a lot of work needed to repair the decades-long rift. cuba wants the u.s. to repeal y.s trade embargo, which is choking its already-weak economy. congress has been reluctant to do that. and president obama has called on the castro government to stop we crackdown on political dissidents who want real democracy. i asked secretary kerry about that. how can you promise them that

any of the changes here will do any of those bigger things? >> i can't promise them. what i can say to them is that we are now engaged in diplomacy and able to help to shed light on what is happening in cuba, help to understand ourselves better what is happening in cuba. we're here. >> reporter: and secretary kerry is meeting behind closed doors with some of those activists tonight. and, scott, that at least is a thorn in the side of the cuban government on what is otherwise a day of celebration. >> pelley: margaret brennan with the stars and stripes for the first time in more than 50 years. margaret, thanks very much. in china today, a 19-year-old firefighter was pulled alive from the smoldering ruins of that chemical warehouse. he had been trapped for 32 hours. ( explosion ) tremendous explosions two days

ago killed at least 56 people, including 21 firefighters. more than 700 were injured. excessive heat warnings are posted across the west tonight. it's hottest in the southwest-- 113 degrees in palm springs and phoenix today, 118 in death valley. triple digits are in the forecast for that area well into next week. it's political heat that hillary clinton is feeling this evening. she campaigned today in iowa and never mentioned the issue dogging her campaign, those sensitive e-mails on her personal server while she was secretary of state. that server is now in the hands of the f.b.i. john dickerson is our cbs news political director and anchor of "face the nation." john, that f.b.i. investigation is sure to push into 2016. how does she weather this period? >> reporter: the clinton team has a two-pronged approach. they're addressing the specific developments on the e-mail

story, but that's a swamp they don't want to get stuck in. instead, say advisors, they want hillary clinton to be seen talking about the issues they say voters say they really care about. th, this week secretary clinton ses talking about her plans to make college more affordable, and she's also picking fights. recently, clinton took on jeb bush over federal funding for thmen's health and marco rubio ther his position that abortion should be restricted in all cases. the hope is that those fights get news coverage and show democratic voters that clinton is willing to fight for the issues they care about. >> pelley: now, at the same time, vice president joe biden has been busy on vacation calling his supporters. what should we make of that? >> reporter: yeah, this has definitely been a working vacation for the vice president and his advisers. they're talking to supporters and political activists to find out how they would mount an operation that would take on hillary clinton, and whether there is a real appetite for a biden campaign. this has unleashed all kinds of rumors in conversations i've had in these early states.

there is some disappointment in some quarters with hillary clinton's campaign, but that's not the same thing as a burning desire to rally behind joe biden, which is what he would need, scott, to take on a campaign which would be no vacation. >> pelley: john dickerson. thanks very much, john. john's guests on sunday will include three presidential candidates, republicans lindsey graham and john kasich, and democrat martin o'malley. a north carolina police officer was back on the witness stand in charlotte today. the officer, who is white, is charged with voluntary manslaughter in the shooting of an unarmed black man. mark strassmann is at the courthouse. >> he was going to assault me. he was going to take my gun from me. >> reporter: randall kerrick said it was kill or be killed in september of 2013. a woman had called 911 to report a home invader banging on her front door. 24-year-old jonathan ferrell hght also have been just looking for help after a single- car accident.

d rrick and other officers responded and claimed ferrell was acting erratically. one fired his taser at ferrell. in this dashboard camera video, thu can see the taser's dot, and ferrell run past. >> the suspect began usgressively coming towards me. >> get on the ground! get on the ground! het on the ground! ( gunshots ) >> reporter: kerrick shot terrell ten times during their struggle. >> no matter what i did, he wouldn't stop. >> i thought i was going to die. >> reporter: ferrell was unarmed and had no criminal record. charlotte-mecklenburg police suspended kerrick without pay. >> that's your handwriting, right? is yes, ma'am, it is. >> reporter: prosecutor theresa postell grilled him. >> ma'am, this was taken just a little bit after i was in a fight for my life. rem sorry if there's a few inconsistencies. >> reporter: georgia ferrell is the dead man's mother.

three days after his death, she utlked to us about officer kerrick. d but i do forgive him. >> reporter: you do? >> i so forgive him, but i do want justice. >> reporter: georgia ferrell told us that her son always hispected police. his sister is a cop. scott, if convicted, kerrick could face 11 years in prison. >> pelley: mark strassmann for us this evening. mark, thank you. long before the "black lives matter" movement, the pioneering hip-hop group n.w.a. was raising its voice against police brutality. 25 years later, the group is the subject of what will likely be this weekend's most-talked-about duvie, and vladimir duthiers has 'rat story. >> you're listening to compton's very own ice cube, easy-e and dr. dre. i got to tell you, you are witnessing history. >> ♪ straight outta compton. >> reporter: they were n.w.a., five guys from inner city los angeles who in 1988 released a eaoundbreaking album, "straight outta compton."

otey come in contact with sediment from the spill. in florida, there is a resurgence in h.i.v. cases, especially among adolescents and young adults. after three decades of medical advances against the potentially vadly virus, why is it on the rise again? vicente arenas is looking into this. >> reporter: 26-year-old jahn cabeza of miami discovered he was h.i.v.-positive two years ago. he remembers stopping at a mobile testing lab and having his world turned upside down. >> i thought, this is the end for me. i used to cry in the bathroom and wake up with my eyes swollen nocause i was crying all night. >> reporter: cabeza's diagnosis is part of an alarming trend. 5,377 floridians were diagnosed with h.i.v. in 2013, according to the florida department of health. that's more than any other state in the nation. dr. michael wohlfeiler is the chief of medicine for the aids health care foundation.

he says 13- to 24-year-old males make up the fastest growing group of new infections. t they were not alive when we went through what i call the holocaust era of aids where everybody was dying from this disease. a young person comes in for his or her first visit with me, the attitude at the beginning of the visit is very nonchalant, like "this is not a big deal." c the end of the visit, often r:e attitude has changed. >> reporter: increasingly, infection rates are also being seen in those aged 50 and older. >> part of the reason that we're seeing new infections in an older group of men who have sex with men is what i would actually term kind of a gay midlife crisis, where they were h.i.v.-negative for years and years, getting tested regularly, and then they went through a period as they were facing middle age of becoming more sexually active. >> reporter: health officials

also say up to 60% of teens and young adults infected don't know they're h.i.v.-positive and are unknowingly spreading the disease. the aids foundation is now trying to create a more aggressive media campaign to remind people that the benefits of safe sex far outweigh the arsks of the disease. vicente arenas, cbs news, miami. >> pelley: the duke and duchess tell the paparazzi "stay away from our kids." and a newborn gets a name that brings a president to tears. when the "cbs evening news" continues. millions of people are estimated to suffer from opioid-induced constipation, oic, caused by the opioids they use to manage chronic pain. oic is a different type of constipation. opioids block pain signals, but they can also block activity in the bowel. i'm really struggling to find relief... ready to paint a different picture? yes!
