(AP) — Relatives of an Omaha man charged with four killings have entered not guilty pleas to charges related to an alleged 10-day

crime spree.

Those who appeared in court Monday included Erica Jenkins. She pleaded not guilty to charges including first-degree murder, two counts of criminal conspiracy and use of a weapon.

Jenkins is the sister of 27-year-old Nikko Jenkins, who is charged with killing Curtis Bradford, Jorge Cajiga-Ruiz, Juan Uribe-Pena and Andrea Kruger over 10 days last August.

Two other relatives and another person also pleaded not guilty to related charges.

Nikko Jenkins’ mother, Lori Jenkins, will appear in court Feb. 21 on charges she bought ammunition for her son and was an accessory in three killings.

Nikko Jenkins will appear for a competency hearing Wednesday.
