The woman suspected in the crime is in custody but the investigation for police continues.
Ruth Pozdol, 38, is in jail awaiting charges in the death of Clifford Van Haywald a man twice her age.
Waterford police arrested Pozdol after she was identified as the suspect who stole the red Chevrolet truck, owned by Van Haywald.
Police say she ran him over as she fled the parking lot of a Burger King in Waterford.
"She's in big trouble, no question," said Lt. Todd Hasselbach of Waterford police. "This is out of character for her to go from petty property crimes to violence. Violence, this is a new one for her."
Detroit recovered Van Haywald's truck Monday. It was found on Detroit's west side burned out.
His family is mourning the senselessness of his death.
"He kept us all together," said Amber Davis, his granddaughter.
Pozdohl, if convicted, is facing life in prison.
