OAKDALE, La. (AP) — An Oakdale man has been charged in the slaying of his grandfather.

Police Chief Scott LaBorde says 18-year-old Laken Johnson is being held without bond in the Allen Parish jail on a second-degree murder charge. It wasn't immediately known if he has an attorney.

Johnson is accused of fatally shooting his grandfather, 64-year-old Norman Ray Johnson, around 9 p.m. Monday at the elder Johnson's home. The defendant lived with his grandfather.

LaBorde says the suspect allegedly shot his grandfather once in the left side with a 12-gauge shotgun. The shotgun was recovered by police.

LaBorde says Johnson confessed to the slaying, but he didn't provide a motive. He says after the shooting, Johnson went to a friend's house and the friend notified police.
