A Baton Rouge man was convicted Saturday in the September 2010 shooting death of a 37-year-old man at an apartment complex on Boulevard de Province off Old Hammond Highway.

An East Baton Rouge Parish jury found Dominique Lamar Rivers, 25, guilty of second-degree murder in the slaying of Derrick Lucas Sr. inside Lucas’ unit at the Myrtle Place Apartments.

Rivers, who also lived at the complex on Sept. 2, 2010, at the time of the shooting, faces a mandatory sentence of life in prison. State District Judge Chip Moore will sentence Rivers on May 30.

Lucas was shot three times in the head. East Baton Rouge Parish District Attorney Hillar Moore III said previously that Lucas was executed.

Prosecutor Steve Danielson argued to the jury that Rivers was burglarizing Lucas’ apartment when Lucas, a cement truck driver, came home early from work and surprised Rivers.

Rivers’ attorneys, Margaret Lagattuta and Scott Collier, argued that Rivers was accused of a crime he did not commit.

Gregory Henry, who also lived at the apartment complex, testified he was sitting in his car in the parking lot when Lucas drove up, got out of his truck and walked to his apartment, leaving his truck running.

Henry said Lucas opened his apartment door, fell to the floor, and Rivers came running out. Henry said a dazed and bleeding Lucas walked to a neighbor’s apartment and banged on the door, but no one answered. At that point, Henry said, Rivers returned, forced Lucas back into his apartment, and three shots rang out.

Henry testified he “immediately” picked Rivers out of a six-person photographic lineup later that day at the police station.

Rivers’ attorneys argued Henry’s trial testimony was wildly inconsistent and did not agree with a taped statement he gave police the day of the shooting.
