The body of Erin Corwin, a pregnant 19-year-old Oak Ridge native who had been missing in southern California since late June, was found 140 feet down a mine shaft on Saturday, authorities said Monday.

Corwin’s body, found with the help of video equipment at about 4:30 p.m. Saturday, was identified at 9:30 p.m. Sunday using dental records, the San Bernardino County Sheriff’s Department said.

A half-hour later, at 10 p.m. Sunday, Christopher Brandon Lee was arrested in Anchorage, Alaska, for the murder of Corwin, the Sheriff’s Department said. An autopsy has determined the death was a homicide.

The Desert Sun of Palm Springs, California, said Lee is a 24-year-old ex-Marine who lived next to Erin and her husband, Marine Corporal Jonathan Corwin, who is also from Oak Ridge, at a desert base in Twentynine Palms, California. Detectives believe that Lee and Erin Corwin were having an affair, and that Lee may have been afraid that his wife Nichole would discover his infidelity, the newspaper said.

Corwin vanished June 28 after telling her husband that she was going to Joshua Tree National Park south of Twentynine Palms. [Read more…]
