MIAMI – (CBSMiami.com) – A gambling dispute turned deadly in Miami when a 19-year-old man allegedly shot another man over $20, Miami police said.

The two men began to argue and other people who were near the area on the 1800 block of Northwest 2nd Avenue broke up the fight.

But witnesses told police that they saw Stevie Brown place a firearm in his pocket and ride off in his bicycle. Another witness told police that at about 3:51 p.m. on November 26th, Brown fired multiple shots striking the back of the head of the man with whom he had the dispute.

Police did not identify the name of the victim on the arrest form.

Brown was charged with first-degree murder. He appeared before a bond court judge Thursday.

A judge ordered him held no bond. Brown told police that he “didn’t kill anyone” and that he “wasn’t even there,” according to the Miami police arrest form.
