SEATTLE — The murder trial has begun in Seattle for a man accused of killing a neighbor in Shoreline in 1975 when they were both 16.

A prosecutor told King County jurors Tuesday that the stabbing of Diana Peterson went unsolved for so long because police focused on the wrong man.

Prosecutors say 50-year-old James Groth stabbed Peterson in the back on Valentine’s night and left her body in her yard where it was found the next morning by her father.

The defense lawyer says the other man, who was the girl’s boyfriend, is still a suspect in the case.
