POMPANO BEACH, Fla. -

"I heard the commotion," said Toniqua Thomas.

Thomas and dozens of other people were nearby when they said the shooting began.

"They was gambling over there," Thomas told Local 10's Baron James. "One person owes the other person money, and wouldn't give him the money. He was trying to run away."

As bullets chased him, the victim ran next door to the parking lot of the Georgia Grocery Store where deputies said he collapsed and died.

BSO K9 units and SWAT showed up to search for the shooter.

A BSO spokeswoman said they know who the killer is, and so do the victim's family and friends who showed up at the scene. One friend said the victim had just come home Monday from working out of town to make money to support his family.

"That's my dog from Liberty Park," Derek Williams said. "He was a working man, was just out here making an honest living. He got a little kid."

BSO had not released the victim's name Monday night, and have not given description of the suspected shooter.

Anyone with information should call Crime Stoppers at 954-493-TIPS.
