A Nashville teen pleaded guilty Thursday to the 2010 murder of his 14-year-old friend.
Donquise Alexander was also 14 when he shot and killed Vincent Lewis.
He pleaded guilty to second degree murder and will serve 30 years in prison.
The shooting occurred on the afternoon of July 8, 2010 outside an apartment building on Sixth Avenue North near Hume Street.
Metro police said Alexander, Lewis and two others had gathered to smoke marijuana.
Alexander left the group and came back with a rifle.
He demanded money and marijuana from Lewis, and after a struggle with the gun, Alexander shot Lewis several times, police said.
Lewis died on the scene and a maintenance man later found his body.
After a three week investigation, Alexander was identified as the shooter, and his mother turned him in to police.
His mother talked to Nashville's News 2 under the condition of anonymity on Thursday afternoon.
She said turning her son in to authorities was one of the most difficult decisions she has ever made.
“That was the hardest day of my life,” she explained, “That was the best thing to do. No running him, no hiding him. I'm a mother, so that's the thing I felt was best.”
Despite her son's guilty plea, and 30-year prison sentence, Alexander's mother maintains her son's innocence.
“In my heart I feel my son didn't do this,” she told Nashville's News 2.
She said she vows to fight to have the guilty plea overturned.
“Being out of options never crossed my mind. Even though he plead out we can still appeal that plea,” said Alexander's mother.
