On the morning of Jeffrey Epstein’s death there was shouting and shrieking from his jail cell, according to a source familiar with the situation who spoke to CBS News.

Corrections officers attempted to the convicted child sex offender while saying “breathe, Epstein, breathe.”

Congress is the latest to start investigating Epstein’s apparent suicide over the weekend, with new reports raising questions about the federal jail where he was being held. One of Epstein’s guards at the Metropolitan Correctional Center on the night he died was reportedly not a regular corrections officer.

CBS report: On Monday, Attorney General William Barr criticized the detention center where the disgraced financier was held. “We will get to the bottom of what happened and there will be accountability,” Barr said. “I was appalled and frankly angry to learn of the MCC’s failure to adequately secure this prisoner.”

Government investigators raided the alleged sex trafficker’s private island in the Virgin Islands Monday.

With Epstein gone, potential co-conspirators involved in his alleged sex-trafficking network are shifting into focus. British socialite Ghislaine Maxwell is one of four women accused of recruiting underage girls for sex. She’s denied those claims in the past and has not been charged with a crime. Maxwell is said to be Epstein’s ex-girlfriend turned business associate. Her current location is unknown.

“She was more of a partner in his obsession, really,” said Miami Herald reporter Julie Brown, who spent more than two years looking into Epstein’s controversial 2008 plea deal. “And there are allegations that she was involved in having sex with some of these girls as well.”

Court documents from 2011 reveal Epstein controlled several apartments in a building just blocks from his $77 million New York townhouse and allegedly housed “underage girls from all over the world.”

Barr also issued a stern warning for anyone who may be evading justice: “Let me assure you that this case will continue on against anyone who was complicit with Epstein. Any co-conspirators should not rest easy. The victims deserve justice and they will get it.”

Epstein’s estranged brother Mark was called and he identified Epstein’s body. The New York City Medical Examiner’s office has performed an autopsy, but the results are still pending.

In an interview with our West Palm Beach affiliate WPEC, a former Florida corrections worker said Epstein was “treated like a celebrity” during his 13-month stint in a county jail after he pleaded guilty in 2008 to charges of soliciting a minor for prostitution. She claims his cell was regularly left unlocked and she saw him move freely through the dormitory area – sometimes completely naked – without repercussions.
