Jonathan Lewis Ginsburg, 32, was last seen at his Albany, California, home on October 7, 1987. Born with mild cerebral palsy and deaf, he communicated with a mix of sign language and speech and wore hearing aids. Authorities list him as an endangered missing person.

Ginsburg had struggled with depression and was reportedly very despondent after a recent failed relationship, so investigators have suspected he may have taken his own life, though his body has never been found and the disappearance remains unsolved. He stood 5 feet 8 inches and weighed about 135 pounds, with brown hair and brown eyes.

Ginsburg studied forestry at Kings River Community College, hoped to be a firefighter but was prevented by his disabilities, and worked at an eye-care product lab in Oakland. He was also an artist honored by the Creative Center in Visalia, which named a gallery for disabled adults after him. Does anyone who knew Jonathan or his routines have information that could help clarify what happened?
