HUNTSVILLE, Ala. (WHNT) -- A third man has pleaded guilty to murder in the December 2012 shooting death of a budding Huntsville rapper.

Mardez Hobbs, 21, submitted the plea this morning before Madison County Circuit Judge Alan Mann. He admitted a role in the killing of Larry “LaChris” Cole on Dec. 4, 2012 at a Huntsville music studio on Poole Drive.

Two other men have previously entered guilty pleas in the case. Christopher Baker pleaded guilty in October and received a life sentence. Travius Washington, who was 17 at the time of the shooting, pleaded guilty to murder in November and received a 30-year sentence.

A fourth man, Dederick Derrick, is set to go on trial in March.

Police said the men plotted to rob Cole, thinking he had money or there was money in the music studio. Baker was the only one who knew Cole. Police said he talked to Cole about buying some marijuana and drove to the studio with the three other men.

Baker went in and smoked marijuana with Cole. At some point Washington was admitted to the studio, carrying a high-powered rifle.

Cole fought back, but was fatally wounded. Baker was also shot, apparently accidentally, in the incident.

Derrick and Hobbs didn’t enter the music studio.

Police said Cole didn't have any money, at most the robbers came away with a small amount of marijuana.
