SAN FRANCISCO – A former Stanford University swimmer whose six-month sentence for sexually assaulting an unconscious woman ignited widespread outrage will leave jail three months early.

Online inmate records show 20-year-old Brock Turner is expected to be released from the Santa Clara County jail on Sept. 2. He was booked June 2.

County jail inmates serve 50 percent of their sentences if they keep a clean disciplinary record. Calls to the county Department of Correction weren’t immediately returned Thursday.

Turner of Dayton, Ohio, was convicted of attacking the woman he met at a fraternity party in January 2015 and was sentenced last week to six months in jail and three years’ probation.

The sentence triggered criticism that a star athlete from a privileged background had gotten special treatment. Prosecutors had asked for six years in prison.

Vice President Joe Biden has written an open letter to the woman who was sexually assaulted after an emotional message she read to her attacker in court gained widespread attention.

Biden, who wrote the 1994 Violence Against Women Act and is involved in the White House’s “It’s On Us” campaign against campus sexual assault, sent the letter to BuzzFeed News on Thursday.

It draws attention to the six-month jail sentence for 20-year-old Brock Turner, which drew outrage.

The vice president wrote to the victim: “I do not know your name – but your words are forever seared on my soul.” He says her statement should be required reading, though they’re “words that I wish with all of my heart you never had to write.”
