DES MOINES, Iowa (AP) — The Iowa Supreme Court has agreed to review the case of a man who was convicted of first-degree murder in the shooting of an Iowa high school football coach. Twenty-six-year-old Mark Becker argued he was legally insane when he killed Aplington-Parkersburg coach Ed Thomas in June 2009. A jury rejected his insanity defense and found him guilty of first-degree murder in 2010. Becker was sentenced to life in prison.

In September, the Iowa Court of Appeals upheld Becker’s conviction, rejecting arguments that jurors were given improper instructions about his insanity defense. Becker appealed to the Iowa Supreme Court. The court, in an order released Tuesday, agreed to review his case.
