Brock Turner and his parents went to the Greene County sheriff's office in Ohio on Tuesday so the former Stanford University swimmer could register as a sex offender—something he'll have to repeat four times per year for the rest of his life, NBC News reports. His registration can be seen here. According to the Los Angeles Times, Turner was convicted in March of assault with the intent to commit rape of an unconscious person, sexual penetration of an unconscious person, and sexual penetration of an intoxicated person after sexually assaulting a woman behind a dumpster on campus. He was released on Friday on good behavior after serving only three months in jail. Turner's mom shielded him from the press and he didn't comment while registering Tuesday.
