>> quijano: good evening. i'm elaine quijano. the f.b.i. and department of justice are investigating the death of jeffrey epstein. one day after his apparent jailhouse suicide, investigators and lawyers have more questions than answers about what happened inside that new york jail at dawn saturday. here's mola lenghi. >> reporter: the bureau of prisons said 66-year-old jeffrey epstein was found unresponsive in his cell early saturday. staff in lower manhattan at the metropolitan correctional center tried to revive him according to the associated press. attorney general william barr said epstein's death raises serious questions. just two weeks ago epstein was found semiconscious on the floor of his jail cell there. sources tell cbs news that following his apparent suicide attempt, epstein told authorities he feared powerful people might be trying to prevent him from cooperating with authorities. "the new york times" reported sunday epstein had been taken off suicide watch and was

supposed to have been checked by guards every 30 minutes, but that procedure was not being followed the night before he was found. sources at the jail tell cbs news they often rely on certain inmates to assist guards in monitoring other inmates due to a lack of manpower. arrested on july 6th, epstein pleaded not guilty to federal charges that he enticed, recruited, and molested dozens of young girls at his homes in new york and florida. marc fernich, one of epstein's attorneys, said there is plenty of blame to go around for this unthinkable tragedy. fernich blames overzealous prosecutors, pandering politicians, judges, jailers, and the attorney says reporters also have blood on their hands in epstein's death. a trial date had been set for june 2020. jennifer araoz alleged that epstein raped her in his new york mansion in the early 2000s when she was 15. "we have to live with the scars of his actions for the rest of our lives while he will never face the consequences." with epstein dead, the criminal

case against him ends, but prosecutors have left the door open to charge coconspirators who were involved in his alleged sex trafficking operation. >> my clients were shocked, distraught, having a hard time processing this. >> reporter: attorney lisa bloom represents several alleged victims of epstein. bloom says her clients still plan to get justice. >> now that he's gone, the criminal case dies with him, and we are going to file civil claims, civil litigation against jeffrey epstein's estate. >> reporter: cbs news has learned that victims are still coming forward and investigators continue to collect evidence, including from epstein's properties, like this opulent townhouse on manhattan's upper east side which will very likely be the target in the civil cases against epstein's estate, which elaine, despite his death will be allowed to move forward. >> quijano: mola lenghi, thank you. jeffrey epstein's death has raised troubling questions about how such a high-profile suspect could apparently take his own

life while in custody. but it's also raising some conspiracy theories, one retweeted by epstein's former friend, president trump. ben tracy has more. >> reporter: shortly after jeffrey epstein was found dead in his jail cell, president trump retweeted this video from a conservative commentator. >> for some odd reason, people that have information on the clintons end up dead, and they usually die from suicide. >> reporter: former president bill clinton was also once friendly with epstein, but there is no evidence at all to support the conspiracy theory the president is fueling. >> why did the president then retweet that clinton suggestion? >> i think the president just wants everything to be investigated. >> reporter: in a statement, a clinton spokesman said the suggestion that the clintons are involved is ridiculous and of course not true and donald trump knows it. >> this is more recklessness. what he is doing is dangerous. >> reporter: republican marco rubio agrees it's dangerous. he says there is evidence russian bots are now pushing

this new conspiracy theory on line to further divide americans. in a tweet, rubio said, "putin has weaponized our polarization." the russians have done this before." cbs news has confirmed a russian disinformation campaign helped push a bogus theory that hillary clinton's presidential campaign paid to have a democratic national committee staffer murdered. police believe 27-year-old seth rich was killed after an attempted robbery three years ago in washington. that russian-fueled conspiracy theory was also promoted by allies of president trump and fox news. president trump is here in new jersey on vacation. he is believed to have spent the day golfing. elaine? >> quijano: ben tracy, thank you. the democratic candidates were out in force today assuring voters they have a plan to curb gun violence, but despite last weekend's deadly mass shootings, new gun policy remains a very tough sell. ed o'keefe reports from des moines, iowa. >> we should have a national

licensing program in this country. >> i'm prepared by executive action to ban the importation of assault weapons into our country. >> we need far more bolder action to make our nation safe. >> reporter: democratic presidential candidates spent yet another day on the campaign trail focused on gun control policy about a week since mass shootings in texas and ohio. >> what we really need to do is also pass a ban on assault weapons, particularly the military-style weapons. >> reporter: democrats are pushing trump and majority leader mitch mcconnell to reconvene the republican- controlled senate to pass a bipartisan bill that passed earlier this year in the house. >> it would pass in any judgment, the president would sign it, and we would take a giant step forward. >> reporter: the president says he would support meaningful changes to the gun background check system, but louisiana republican congressman steve steve scalise, who survived an assassination attempt, doubts it would help. >> the shooters el paso and dayton passed background checks. we need the make sure f.b.i. and

the department of homeland security have the tools they need to root out, whether it's white supremacists, whether it's radicals from the left that are committing some of these crimes. >> reporter: here in the first- in-the-nation caucus state of iowa, voters agree the nation's gun laws need changing, but they want to hear other topics. >> the small legislation the democrats are asking for is not much. just background checks. >> you can talk about red flags and background checks. the bottom line is we have weapons of war in people's hands who don't need them. >> i don't like the mudslinging. that can turn me off. here we have iowa nice. >> quijano: so, ed, voters in iowa get far more detailed look at these presidential candidates. what else are they telling you they're interested in or concerned about? >> for one thing, elaine, they are overwhelmed. two dozen candidates remain in the race. you ask the everyday iowan to name a presidential candidate or two, they might be able to mention joe biden, bernie sanders, elizabeth warren, but that's it. and it's a sign that they perhaps are hoping that the

field st t as for the issues, here in iowa and across the country, there seems to be great support for expanding background checks and maybe looking at some other gun laws, but there is more concern, more interest in healthcare, the future of the economy, and climate change. it will be interesting to see if the candidates will keep the focus this coming week on gun o sothing else. elaine? >> quijano: ed o'keefe in iowa, ed, thank you. muslim worshipers and israeli police battled at a jerusalem holy site claimed by both muslims and jews. police used tear gas and stun grenades on the worshipers in the worst fighting at the site in months. palestinian medics report at least 14 people were wounded. in norway, a gunman was arrested for attempted murder at a mosque on saturday. the young suspect entered an oslo mosque armed with multiple weapons and opened fire but was overpowered by two men in their 60s.

>> hong kong has never had democracy, true democracy, so i think anyone in power is not willingly going to give it to you. you're going to have to take it from them. >> reporter: and that battle has been ramped up. the relentless hit and run-style protests are being met with a far more formidable police response. this woman was hit in the eye with a beanbag bullet, filled not with beans but lead pellets. debora patta, cbs news, hong kong. >> quijano: breaking news, curtis watson, the escaped convict who was the subject of a massive five-day manhunt, has been captured. watson broke out of a tennessee prison. police say he sexually assaulted and killed a prison executive before riding off on a tractor. jonathan vigliotti has the stunning details. >> reporter: convicted kidnapper and accused rapist and murderer curtis watson busted in the back

of a cop car and no longer a fugitive after five days on the run. just hours before his capture, watson was caught on surveillance camera dressed in camouflage rifling through a refrigerator on a property not far from the prison. the manhunt started august 7th when watson celebrated his 44th birthday by breaking out of the west tennessee state prison where he was serving a 15-year sentence for aggravated kidnapping. he had a previous conviction of aggravated child abuse. police say he disappeared after starting work detail mowing the prison lawn. he vanished on a tractor and wasn't reported missing for an hour. in that time, an affidavit filed the next day says he sexually assaulted and strangled to death prison administrator debra johnson. johnson was a 38-year veteran of the tennessee department of corrections. she leaves behind two sons and a daughter. >> he tore our family apart with this. it hurts.
