WASHINGTON, Mo. (AP) – Authorities say they’ve located the pickup truck of a northwestern Missouri man they say has been on the run with his missing son.

Washington, Missouri, police Detective Sgt. Steve Sitzes tells the Washington Missourian (http://bit.ly/2gJuYxx ) that 32-year-old Anthony D. Davis’ truck was found Tuesday in a trailer park in Washington, in eastern Missouri.

Davis and his 7-year-old son, Seth Davis, still have not been located and have been the focus of a statewide search since the two went missing earlier this month. Anthony Davis was to return the boy to his mother Dec. 4 but never showed up.

The Missouri State Highway Patrol says Anthony Davis suffers from a mental health issue and is believed to be off of his medications.
