LOGAN COUNTY, Oklahoma - The Logan County Sheriff's Office has canceled an Amber Alert for two young boys who were feared missing. They have been located.

Earlier Tuesday afternoon, deputies said Dillon Nelson, 4, and Evan Nelson, 7, were taken by their mother, Jessica Evans. They were last seen at 1:30 p.m. in the 13000 block of N.W. 1st Street in Oklahoma City.

Deputies said Evans has openly made threats to kill her children, saying she would drive into Lake Overholser before she let their father have visitation rights.

Police say Jessica Evans is a drug addict who has threatened to kill her children rather than surrender custody. She is 29, 5'8" tall with blue eyes and red hair.

Evans was last seen driving a 2005 red Chrysler Pacifica. It has an Oklahoma license plate number of 703-GOQ.
