FARGO -- Authorities in the Fargo area are searching for the remains of a 45-year-old Vadnais Heights, Minnesota woman allegedly killed by a 51-year-old man.

Timothy Barr, of Lakeville, Minnesota, is charged with two counts of second degree murder without intent and criminal vehicular homicide. Police say Barr told two people he accidentally ran over Michelle Newell with his car.

The Cass County Sheriff's Office in Fargo is asking anyone with farm property to check for anything unusual.

Newell's family reported her missing on Sept. 8. Cass County deputies questioned Barr near Interstate 94 in North Dakota on Aug. 31 after someone called to say a man was lying in a ditch.

Barr allegedly told a police informant that he and a woman were going to South Dakota to sell methamphetamine.
