OMAHA, Neb. (AP) — A judge has ruled that a man convicted of killing four people in Omaha last summer should undergo a psychiatric evaluation in prison, rather than being taken to a state psychiatric hospital.

Douglas County District Judge Peter Bataillon issued the ruling Friday after prosecutors argued that moving Nikko Jenkins from the Lincoln prison where he’s being held to a psychiatric hospital would pose a security risk.

A defense psychiatrist says Jenkins’ mental state had deteriorated since he was convicted in April of four counts of first-degree murder.

Jenkins is awaiting sentencing for the August 2013 deaths of Curtis Bradford, Jorge Cajiga-Ruiz, Juan Uribe-Pena and Andrea Kruger.
