NORTH MIAMI, Fla. -- Police have arrested a man in connection with the death of a beauty store owner who was shot execution-style in the head.

Emmanuel Jean was charged Tuesday with the first-degree murder of Mohammed Ayoub.

Ayoub was executed May 30 outside the door of the $ & Beauty shop he had owned for about five years after he tried to protect his business from being robbed, police said. Ayoub, 60, was airlifted to Jackson Memorial Hospital, where he was pronounced dead.

Police said Jean, 19, was linked to Ayoub's death through forensic evidence and eyewitnesses.

Ayoub's shop did not have surveillance cameras, but a nearby Discount Auto Parts did. It was that video that helped police put together a composite sketch of the suspected shooter.

Police said Jean has an extensive criminal history. He is also charged with armed robbery and possession of a firearm by a delinquent.
