Police say Johnson was driving to his parents’ home April 9, 1977, when three men blocked the roadway with their car on San Carlos Way. The three men walked up to Johnson, who was still in his car, investigators say.
Johnson was shot in the upper body after a brief struggle, police say. He was then robbed and the three men fled in their red or brown Ford Pinto.
They were never caught.
Because Johnson died from complications stemming from the shooting, his death is considered a homicide.
