An 18-year-old Baton Rouge man was indicted on a first-degree murder charge Thursday in the May 10 shooting death of a man on Tecumseh Street.

An indictment returned by an East Baton Rouge Parish grand jury alleges Montell Murray, 5236 Adams St., “had the specific intent to kill or inflict great bodily harm upon more than one person.’’

Police have said Keenan Myles, 21, 2845 Tecumseh St., was standing with five other people in front of a home in the 2900 block of Tecumseh at about 9 p.m. when he was shot.

Police said Murray confessed to the shooting.

First-degree murder is punishable by either death by lethal injection or life in prison.

“We are exploring all of our options,’’ state Attorney General’s Office spokeswoman Amanda Larkins said when asked if the death penalty would be sought in the case.

East Baton Rouge Parish District Attorney Hillar Moore III said his office recused itself from handling the case because of a conflict of interest.

The grand jury also indicted Kimberly Daigre, 24, 6666 Myrtlewood Drive, and Christopher Pender, 21, as accessories after the fact.

Daigre and Pender are accused of “harboring, concealing or aiding’’ Murray, the indictment states.

Murray also was indicted as a felon in possession of a firearm and on other weapons charges.

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