Colby Martin, of White Pigeon, was initially charged with manslaughter after he allegedly struck Melody Rohrer with his car on September 20 and moved her body about 26 miles southwest, Van Buren County Sheriff's Office said at the time.
Prosecutors upgraded his charges to open murder during a hearing at Van Buren County District Court on Wednesday, after investigators revealed that Martin searched necrophilia-related pornography immediately after Rohrer’s death, ABC 13 reported.
