(AP) — The Douglas County Sheriff’s Office says a man believed to have helped commit one of four linked Omaha killings last month has been arrested.

The Douglas County Sheriff’s office says Warren J. Levering was arrested Wednesday on the Winnebago Indian Reservation in northeast Nebraska. Authorities had issued an arrest warrant for the 51-year-old Levering a day earlier.

Levering is accused of being an accessory to a felony in the Aug. 21 death of 33-year-old Andrea Kruger, who was shot and killed in an intersection northwest of Omaha as she was headed home from work.

Prosecutors have charged 26-year-old Nikko Jenkins, who is Levering’s nephew, with four counts of murder in connection with Kruger’s death and three other killings.

Levering is in the custody of the Douglas County Sheriff’s Office.
