The 13-year-old boy accused of killing Alyssa Neitz has pleaded guilty to negligent homicide.

Neitz, 17, was shot and killed on February 23, 2018, in Ouachita Parish. Witnesses say the 13-year-old put a gun to her head, said it wasn't loaded, then pulled the trigger in an attempt to prove it.

In May, the family recently denied a request that would give the suspect five years of probation. At the time, the family said they were hoping for a tougher sentence so the boy can have time to grow in a different environment.

The teen is being held in the Green Oaks Detention Center. He has not yet been sentenced.
