SEMINOLE, Oklahoma -- Detectives wrap up a murder investigation  in Seminole County. Now the District Attorney is filing charges on two suspects in the death of Veronica Carlson.

In a probable cause affidavit, one of the two suspects admit to and describe the details of Veronica Carlson's murder. Now the district attorney, is filing charges on Roger Gober and his fiancee Marylee Smotherman.

Gober and Smotherman are both charged with first degree murder and desecration of a human corpse.

Gober told investigators his fiancee Marylee Smotherman stabbed his ex-girlfriend Veronica Carlson three times before telling Gober to cut Carlson's throat and bury the body.

Investigators found Carlson's body in a shallow grave in Seminole County on October 25, almost two weeks after Carlson's roommate reported her missing.

The court papers also show a third person was the scene of the crime, picked up the knife and tossed it under the car. Prosecutors have not filed any charges on the third person.

Gober and Smotherman go before a judge for arraignment on Friday.
