Petaluma police are looking for clues to the identity of a knife-wielding man who attacked a stranger with a large blade on a west-side street corner late Thursday night.
The 20-year-old victim sustained only superficial wounds despite the surprise 11:50 p.m. slashing on Western Avenue at Upham Avenue, police said.
But it was utterly unclear what prompted the behavior of the perpetrator, who wore a sheath containing the large Bowie-style, fixed-blade knife with which he attacked his victim, authorities said.
The victim had just left a friend's house and was walking on Western Avenue when the hoodie-wearing stranger suddenly attacked him, pulling the knife from its sheath, police said.
The suspect then ran, allowing the victim to call a friend who picked him up and took him to Petaluma Valley Hospital for treatment.
