A judge has found a 27-year-old man guilty of murder in the shooting deaths of four people in Omaha last summer. 

Judge Peter Bataillon allowed Nikko Jenkins to plead no contest Wednesday to four counts of first-degree murder and eight weapons counts and then found him guilty on all counts. 

Jenkins is acting as his own attorney.  He is accused of killing four people in three separate attacks over 10 days after he was released from prison on July 30. 

Jenkins had previously pleaded not guilty, claiming he didn't receive proper mental health treatment while in prison. 

Judge Bataillon made sure Jenkins was aware that no contest pleas are treated as guilty pleas for the purposes of sentencing.

Jenkins could still face the death penalty. A three judge panel will decide the punishment.

Jenkins initially plead guilty to all of the charges Wedneday morning.  But after Douglas County Attorney Don Kleine outlined the crimes in detail, Jenkins claimed the state's evidence was incorrect, and that he didn't remember killing anyone.

He also claimed that voices told him to sacrifice the four victims.
