The Palm Beach County Sheriff's Office is trying to piece together what led up to a double murder-suicide at a local Publix.
Detectives say a woman and her grandson, just shy of his second birthday, were shot to death by 55-year old Timothy J. Wall of Royal Palm Beach at the supermarket near the intersection of Royal Palm Beach and Okeechobee Boulevards before noon on Thursday.
The motive is unknown and Sheriff's Spokeswoman Teri Barbera says they're unsure about the relationship between Wall and the two victims.
Publix issued a statement reading in part, "Our thoughts are with those who are impacted by this tragedy. We are cooperating with the local law enforcement."
