Summary based on the NamUs case record (MP4372) and 4 other sources
Luke Robinson, a 25-year-old man, was last seen on July 1, 1990, in West Hollywood, California. He stood around 6'0" to 6'2" and weighed approximately 140 pounds at the time of his disappearance. Luke had brown hair and brown or hazel eyes, and he was known to have a strawberry birthmark under his left arm. Additionally, he was missing two front teeth, which had been replaced with false teeth.

At the time of his disappearance, Luke was struggling with mental health issues, including bipolar disorder, and possibly schizophrenia. His condition may have been exacerbated by drug use. He was possibly wearing Gothic-style clothing on the day he was last seen, but few other details about his last known movements are available.

Robinson disappeared under suspicious circumstances, and foul play has not been ruled out. Despite investigations, there have been no significant leads, and Luke remains missing. Authorities, including the Los Angeles County Sheriff's Department, continue to urge anyone with information to come forward in hopes of resolving the case.
