A 30-year-old registered sex offender and parolee with the numerals "666" the Mark of the Beast tattooed over his right eyebrow is in Riverside jail after he drove to a Sheriff's station in Lake Elsinore and told deputies that he had the body of a woman in the trunk of his car, authorities said.

Jason Richard Budrow, a resident of the Goodhope section of Riverside County, was arrested on suspicion of murder and booked at the Southwest Detention Center.

Budrow flagged down a sheriff's sergeant on Friday to tell him about the body. Since then, investigators have determined that Budrow knew the victim and had a "dating relationship" with her.

The woman's name was not released, pending notification of her next of kin.
