An East Baton Rouge Parish grand jury Wednesday indicted a Baton Rouge man on a count of second-degree murder in a 2010 fatal armed robbery.

Thadius Brothers, 28, was charged with shooting 33-year-old David Lee Mitchell during an August 2010 robbery.

The indictment comes nearly four years after another grand jury did not find enough evidence to bring charges against Brothers in Mitchell’s slaying.

A month after Mitchell’s death, prosecutors say Brothers shot and killed a man who had identified him as the killer to investigators.

Brothers is accused of breaking into the home of a sleeping Robert Winfield, 37, and shooting him in the forehead, investigators have said. Brothers is set to go on trial in that case later this month.

Under Louisiana law, a second-degree murder conviction carries a mandatory penalty of life in prison.
