A San Francisco psychiatrist who pleaded guilty to possession of child pornography was stripped of his medical license this week.
A federal judge last year sentenced Billy Lockhart to three years in prison, which he began serving in November, according to court records. Lockhart was a resident of UC San Francisco’s Department of Psychiatry when he was arrested in May 2017 as part of a San Francisco Police Department probe into online child pornography trading.
Investigators found hundreds of videos and graphic images of child pornography on various devices that belonged to Lockhart during a search of his home. Authorities said he uploaded and traded the pornography online, at times while he was at work.
“Many of the images contained pre-pubescent minors who had not attained the age of 12 years and some images depicted sexual abuse or exploitation of an infant or toddler,” the state medical board wrote in a decision published Wednesday. “Also, some of the images portrayed masochistic or sadistic or violent conduct.”
