“I just heard three loud pops and next thing I knew they were chasing everyone out of the store," Downs said.
Palm Beach Sheriff's Office officials said deputies responded to the shooting and found the man, woman and child dead.
Officials said the woman was the child's grandmother. The child would have turned two years old later this month, officials said.
Their family invoked Marsy's Law, and law enforcement will not be releasing the names of the woman and the child.
Authorities identified Timothy J. Wall, 55, as the gunman. There is no known motive or relationship between Wall and the victims, the Palm Beach Sheriff's Office said.
Witnesses said they heard three gunshots and then started running for the store's exits.
"Everyone started coming out yelling 'Active shooter! Shots fired! Get out! Get out!' and I saw about 50 customers and staff leave I would say in about 10 or 15 seconds," witness Ron Glassman said.
