WICHITA, Kan. (AP) — The Kansas Supreme Court has upheld a murder conviction for a Wichita man who took part in the shooting death of a 13-year-old boy.

The court on Friday rejected an appeal from Eli Betancourt, who was convicted of premeditated first-degree murder in the June 2010 death of Miguel Andrade. The boy was shot several times when he opened his front door after hearing sounds outside.

Prosecutors say Betancourt and three other men fired on the wrong house as they sought vengeance for an attack on a relative of Betancourt’s. He is serving a Hard 25 life sentence.

Betancourt’s attorney had argued that the Sedgwick County court made several errors during the trial, including admitting his police statement as evidence, and that there was not sufficient evidence to convict him.
