SHELLSBURG, Iowa (AP) — The death of a woman whose body was found near a stolen truck in eastern Iowa has been ruled a homicide.

The Iowa Division of Criminal Investigation said Wednesday that an autopsy on Sabrina Hustad shows her death was caused by multiple stab wounds and strangulation.

Hustad was found Sunday near a stolen truck in Benton County. Two men examining the truck noticed blood on a door handle and saw a blood trail. They followed the blood and found Hustad.

Hustad’s body was found near the residence of a man who is being housed at the county jail on charges of probation violation and second-degree theft. Authorities have not said whether the man is connected to the death.

The case remains under investigation. Additional information has not been released.
