Brock Turner, the former Stanford University swimmer who was sentenced to six months in jail for sexually assaulting an unconscious woman behind a dumpster outside a fraternity party in January 2015, will most likely be released on September 2, authorities tell PEOPLE.

A September 2 release would mean Turner will have spent three months in jail. Prosecutors had asked Turner be sentenced to six years in prison.

“We run the jails and it is our job for the care and custody of the inmates and we are advised from the court when to release any inmate and as of September 2 we are ordered to release Brock Turner,” Sgt. James Jensen of the Santa Clara County Sheriff’s office tells PEOPLE.

However, Jensen says, “We as the sheriff’s office can lengthen his sentence if there are some behavioral issues up to six months.”

Turner, who has been in jail since June 2, is in protective custody, says Jensen.

“He is housed in an area where there are 48 different cells and approximately 90 inmates,” he says.

Jensen says 90 percent of inmates who are either convicted or charged with a sexual assault are put in protective custody.

“We have them in protective custody because we believe there could be an issue with other inmates that are in general population so we keep protective custody inmates together,” he says.

Turner’s six-month sentence drew widespread criticism and gained national attention after the survivor shared an emotional letter directed at Turner, which she read in court after his sentencing.

Turner was convicted of three felony counts of sexual assault. He has admitted to the sexual contact but maintained it was consensual.

A spokesperson from the Santa Clara County District Attorney’s Office tells PEOPLE: ‘We hope the worldwide discussion of this crime sentence and the victim’s powerful letter has helped raise awareness about campus sexual assault.’

In a newly released statement to the judge, Turner cited alcohol and drinking culture as reasons for his actions, and mentions the loss of his athletic scholarship and Olympic dreams.
