A man charged with four counts of first-degree murder in the slayings of four Omaha people last summer is expected to plead guilty to the charges in court on Wednesday.

Douglas County District Judge Peter Bataillon scheduled the hearing after Nikko Jenkins filed a hand-written motion Friday saying he wants to plead guilty. Jenkins is acting as his own attorney in the criminal case.

Jenkins is accused of shooting to death four people in three separate attacks over 10 days after he was released from prison on July 30. 

Jenkins had previously pleaded not guilty to four murder and eight weapons charges, claiming he didn't receive proper mental health treatment while in prison.
