Crime Watch Daily investigates the case of an Army recruiter, his teenage lover and his dead wife.

Cati Blauvelt, 22, was found brutally stabbed to death in the cellar of an old abandoned house deep in the woods in Simpsonville, South Carolina on October 25.

Now her estranged husband John Blauvelt has disappeared into thin air. Police say he took 17-year-old Hannah Thompson with him.

Blauvelt, 28, is an Army veteran who worked as a recruiter at local high schools.

Cops begin their investigation of the murder of Cati Blauvelt with a visit to the house of John Blauvelt. They find John with 17-year-old Hannah Thompson, a young woman whose parents complained about underage partying at Blauvelt's house. Blauvelt is served a search warrant, and Hannah was with him. They were both asked questions about Cati's murder, according to investigators.

After talking with John and Hannah, police continue their investigation for over two weeks before taking the next big step. They charge John Blauvelt in the murder of his wife.

But cops now believe John saw his arrest coming. He disappears, and he takes Hannah Thompson with him.

Just this week, a huge development: Hannah's parents tell Crime Watch Daily that Hannah Thompson made contact with them, and she is safe. The chief of the Simpsonville Police Department said she was found in Oregon, but wouldn't provide any other details.

Police say John Blauvelt was driving a 2000-model red GMC Yukon SUV when he left home. Authorities have information that it has potentially been painted either black or primer-gray with spray-paint.

The U.S. Marshals Service has turned this search into a nationwide manhunt.

John Blauvelt remains missing and should be considered armed and dangerous. The U.S. Marshals are offering a $2,500 reward for information that leads to his capture. He was last seen in a 2000 GMC Yukon with South Carolina license plate #JKY829.

Investigators say they've received information Blauvelt's been seen in California, Arizona and New Mexico, and the vehicle has been spotted by license-plate readers along the U.S.-Mexico border.
