Instead, Wurtzel, who also had been convicted of sexual battery in a previous case, found a better option: For $100 a night, he was permitted by the court to avoid county jail entirely. He did his time in Seal Beach’s small city jail, with amenities that included flat-screen TVs, a computer room and new beds. He served six months, at a cost of $18,250, according to jail records.

Markin learned about Wurtzel’s upgraded jail stay only recently, from a reporter. “I feel like, ‘Why did I go through this?’” she said.

In what is commonly called “pay-to-stay” or “private jail,” a constellation of small city jails — at least 26 of them in Los Angeles and Orange counties — open their doors to defendants who can afford the option. But what started out as an antidote to overcrowding has evolved into a two-tiered justice system that allows people convicted of serious crimes to buy their way into safer and more comfortable jail stays.

An analysis by the Marshall Project and the Los Angeles Times of the more than 3,500 people who served time in Southern California’s pay-to-stay programs from 2011 through 2015 found more than 160 participants who had been convicted of serious crimes including assault, robbery, domestic violence, battery, sexual assault, sexual abuse of children and possession of child pornography.
