A call about a burned vehicle in Guthrie County led to the discovery of a body. Deputies answering the 911 call discovered the body inside the burned out car and called in state investigators.

The State Medical Examiner and DCI determined the body was that of Bobby Joe Knapp. Knapp was the subject of a search by the U.S. Marshals Service which issued warrant  on him Thursday for a parole violation. The DCI says the vehicle where his body was found had been reported stolen in Waukee.

Fire investigators are trying to determine how the vehicle caught fire, and the medical examiner is waiting on lab tests to rule on Knapp’s cause of death.
