A 21-year-old Baton Rouge man was indicted Wednesday in the fatal July 31 shooting of a man during what police deemed a drug deal that turned deadly.

Ameer Laymon, 1435 Chippenham Drive, was charged by an East Baton Rouge Parish grand jury with second-degree murder in the killing of Gregory Short, 23, also of Baton Rouge.

Laymon is accused of arranging and being present for the marijuana transaction that led to the slaying of Short on Carolyn Sue Drive, arrest documents show.

Laymon faces a mandatory sentence of life in prison if convicted of second-degree murder.

The case has been assigned to state District Judge Trudy White.
