(AP) — A Wednesday hearing is set on a motion by the defendant to plead guilty to killing four people in Omaha last summer.

Douglas County District Judge Peter Bataillon (buh-TAL’-yuhn) scheduled the hearing and is expected to tell 27-year-old Nikko Jenkins that he is giving up several rights by changing his earlier pleas.

Jenkins filed the motion Friday. He’d previously pleaded not guilty to four murder and eight weapons charges. Earlier last week Jenkins tried to plead no contest to the charges, but Bataillon said he wouldn’t accept the pleas because of the severity of the cases. In February Bataillon ruled that Jenkins was mentally competent to stand trial.

Police say the four victims were shot in the three weeks after Jenkins’ release from prison on July 30, 2013.
