Turner registered as expected in Greene County outside Dayton after being released last week from a jail in California, CNN quoted Greene County Sheriff Gene Fischer as saying.
Turner is required to register as a sex offender for life, and had been expected to return to his family's home in Greene County after his release on Friday.
The 2015 assault drew country-wide attention three months ago, when Turner was sentenced and the victim's wrenching impact statement went viral. The brevity of Turner's sentence -- six months, with eligibility to be released after three -- sparked outrage against the judge and controversy over how the justice system treats sexual assault survivors.
Authorities say Turner, now 21, sexually assaulted a woman after both attended a fraternity party near Stanford in January 2015.
Turner was found guilty early this year of three felony counts: assault with intent to commit rape of an intoxicated or unconscious person, penetration of an intoxicated person and penetration of an unconscious person, CNN reported.
In the victim impact letter she read in court before Turner's sentencing, the woman described blacking out at the fraternity party and waking up in a hospital with pine needles in her hair, dried blood and bandages on the backs of her hands and elbows, her underwear missing.
She described finally learning what happened to her through news reports: how she was found unconscious behind a dumpster between two fraternity houses, her dress pulled over her shoulders, her bra pulled down, naked from the waist down. Two passers-by stopped when they saw Turner grinding against her unconscious body; he ran and they chased after him, pinning him to the ground until police showed up.
