OMAHA, Neb. (AP) — A judge has found the mother of an Omaha man convicted of killing four people guilty of being an accessory.

On Friday Judge Peter Bataillon (buh-TAL’-yuhn) found 48-year-old Lori Jenkins guilty on two counts. He’d heard the case without a jury.

Her son, Nikko Jenkins, is awaiting a June death penalty hearing. He was convicted of first-degree murder for shooting to death Juan Uribe-Pena, Jorge Cajiga-Ruiz, Curtis Bradford and Andrea Kruger in the 10 days after his release from prison in July 2013.

Prosecutors say Lori Jenkins concealed evidence about the purchase of ammunition her son used and helped dispose of clothing that had gunshot residue on it. She was acquitted of a third count.
