The Los Angeles detention center where Nick Reiner finds himself facing two first-degree murder charges is renowned for its celebrity occupants and challenging conditions.

Twin Towers Correctional Facility, known for its focus on mental health, has been a temporary home to a number of high-profile figures, including Paris Hilton and Harvey Weinstein, as confirmed by Page Six.

Back in 2007, Hilton served a brief period at this facility as part of a 45-day sentence for breaching probation linked to alcohol-related reckless driving offenses that occurred the previous year, according to various reports from that time.

In July 2021, Weinstein was relocated from New York’s Wende Correctional Facility to Twin Towers to confront new charges related to sexual misconduct.

Another notable inmate was Conrad Murray, Michael Jackson’s physician, who faced a four-year sentence for involuntary manslaughter in connection with the pop icon’s 2009 passing. Murray spent a short stint at Twin Towers before being moved to other institutions.

Other famous faces who had brief stints at Twin Towers include actor Robert Downey Jr., “Jackass” star Steve-O, convicted murderer Robert Durst, rapper The Game and other stars.

But the jail’s star-studded history doesn’t mean the facility has lux accommodations, as Twin Towers has been accused of harsh conditions.

Beverly Hills Defense Attorney Adam Michael Sacks exclusively told Page Six, “You don’t want to be there, it’s disgusting. Every client I went to visit begged for bail.”

As for the food, Sacks described it as “slop.”

“The food is disgusting,” he added. “It makes cafeteria food look good.”

New York Post elaborated on the harsh conditions inside the facility through inspection reports and court filings.

The Post reported county commissioners have claimed cells have feces on walls, urine on floors and concrete walls covered in graffiti.

Sheriff’s deputies have shut off water to cells — including drinking water — when toilets are intentionally flooded, inspection findings claim.

California Attorney General Rob Bonta filed a lawsuit against the Los Angeles County, Sheriff’s Department and Correctional Health Services regarding the alleged “inhumane” conditions in September.

The lawsuit claims Twin Towers is filled with mold and rust, while rats plague housing units and black worms infest shower stalls.

The Los Angeles Sheriff’s Department told The Post that $309 million went into upgrades — including hiring more staff, fixing infrastructure and other improvements despite the claims.

Twin Towers Correctional Facility did not immediately respond to Page Six’s request for comment.

Rob, 78, and Michele, 70, were found stabbed to death in their Brentwood home in Los Angeles in the afternoon of Dec. 14.

According to the death certificate released on Tuesday, Rob and Michele died within “minutes” from “multiple sharp force injuries” with a “knife, by another.”

Sources initially told The Post that Nick was considered a person of interest in the fatal stabbings.

Nick fled the scene and was arrested in connection to the murders later that evening.

The “Being Charlie” co-writer was officially charged with two counts of first degree murder in his parents’ deaths.

He is reportedly being held on suicide watch, law enforcement sources told TMZ, and is due back in court for his arraignment on Jan. 7, 2026.
