It may not be related, but Sacramento County sheriff's detectives want to find a vehicle of interest in a man's murder at a Home Depot parking lot earlier this last week.

Hassan Alawsi, 46, was shot and killed around 7:30 p.m. Sunday in the store lot at 4641 Florin Road in south Sacramento.

The motive remains unknown.

Sheriff's investigators are looking for a 2005 or 2006 teal green Buick Le Sabre sedan that was seen on security camera images in the parking lot approximately 10 minutes before the shooting, and then leaving the south-end parking lot exit to eastbound Florin Road after the shooting.
