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."
It's the latest incident of violence involving gun use that has some calling for change. Outspoken Parkland parent Fred Guttenberg tweeted "To every Senator who believes protecting the filibuster is more important than protecting the American family, we will replace you."
Palm Beach County Commissioner Melissa McKinlay asked for thoughts and prayers for the victims. She took to Twitter to say "No politics today. Just prayers." But she did note "We've become too numb to gun violence" and "Tomorrow we must step up and engage in a very honest conversation about why this happened and what we can do specifically to prevent this violence." McKinlay closed her tweet with "Inaction is not an option."
Publix remained closed for the rest of the day with PBSO saying all personal items left behind by workers and shoppers are safely bagged and can be picked up on Friday.
The grandmother and grandson's names are not being released, at the request of family members.
