DETROIT  — A teenage boy has been sentenced to serve 25 to 50 years in prison for killing his 36-year-old mother in their Detroit home.

Joshua Smith was sentenced Friday in Wayne County Circuit Court.

The 14-year-old shot and killed his mom, Tamiko Robinson as she slept on Feb. 27. Police say the shooting followed an argument.

Smith was charged as an adult and pleaded guilty to second-degree murder in September.

In a statement to police, Smith said he was tired of being called names. His stepfather’s shotgun was used to kill Robinson.
