Michael Arnold, 46, was shot and killed on October 19, 2008, while walking in San Diego’s Mountain View neighborhood. He was on the 3800 block of Teak Street when a dark sedan carrying three males in their late teens or early twenties slowed near him; one occupant opened fire. Arnold was taken to a trauma center and died later that afternoon. The motive remains unknown and police have asked the public for information in the investigation.

Anyone who was in the Mountain View area of Teak Street that afternoon or who has information about the dark sedan or the three occupants is asked to come forward.
