Prosecutors feel confident they have the evidence to convict an Omaha man charged with killing four people in the weeks after he was released from prison this summer.

They now must prepare for his likely insanity defense and how that might affect prosecutors' attempt to seek the death penalty.

Douglas County Attorney Don Kleine said Wednesday that he would seek the death penalty for 27-year-old Nikko Jenkins, who was ordered Tuesday to stand trial on four counts of first-degree murder and a bevy of weapons counts. Jenkins is accused of shooting four people to death in three separate ambushes carried out in August.

Kleine presented incriminating evidence during Jenkins' preliminary hearing Tuesday, including police testimony that Jenkins' DNA was found on a 12-gauge deer slug recovered from one victim's vehicle.
