(Des Moines, IA) — The final defendant in the fatal 2022 drive-by shooting at Des Moines East High School has been sentenced to life in prison with the possibility of parole.

Nyang Mai Chamdual pleaded guilty to first-degree murder in the shooting that killed 15-year-old Jose Lopez and injured Kemery Ortega and Jessica Lopez Torrez. On March 7, 2022, three vehicles drove past and fired shots at the teens as they stood outside East High School. According to the Polk County Attorney’s Office, Chamdual fired shots from the back of a truck using a revolver.

Chamdual was 14 years old at the time of the shooting and has been held at the Boys State Training School in Eldora. Because of his age at the time of the crime, he is eligible for parole despite receiving a life sentence.

In addition to his life sentence, Chamdual must also pay $150,000 in restitution to the estate of Jose Lopez.

He is one of 10 individuals who were charged in connection with the shooting.
