SAN BERNARDINO, Calif. (AP) -- The alleged lover of the pregnant missing wife of a U.S. Marine based in Southern California has been arrested in Alaska on suspicion of homicide nearly two months after the 20-year-old woman's disappearance from her Southern California home sparked a massive search, authorities said Monday.
Christopher Brandon Lee, 24, was arrested at 9 p.m. Sunday at a traffic stop on an extradition warrant out of California, where San Bernardino County authorities want him for homicide, said Jennifer Castro, a spokesman for the Anchorage Police Department.
San Bernardino County authorities declined to discuss the arrest before a news conference set for Monday afternoon.
Corwin was in the early stages of pregnancy when she disappeared from her home in Twentynine Palms, California on June 28. Her husband, Marine Cpl. Jonathan Corwin, reported her missing the next day.
The investigation grew to focus on Lee, who was the Corwin's neighbor, according to court papers first obtained last month by The Desert Sun newspaper.
Erin Corwin's friend told investigators that Corwin and Lee were having an affair and that the unborn child might be Lee's, the papers show.
Corwin told her husband when she left that day that she was going to scout out good hiking trails that she and her mother could explore when her mother visited a few days later. But the friend showed authorities text messages that said Corwin was planning to go on a special hunting trip with Lee the day she disappeared to celebrate.
"It is highly likely that Erin could have been harmed by an unknown firearm," investigators wrote in the documents. "Sometime after Erin left with Lee, her phone was deactivated (turned off). Detectives believe if Erin was injured and left at an undisclosed location, she would not (be) able to call for help."
Lee, a former Marine, told investigators he was not with Corwin that day and had been hunting in Joshua National Park. He told police that although the two had kissed, they had never had intercourse.
It wasn't immediately clear if Lee, who has yet to make a first court appearance or arrive in California, had retained an attorney.
Lee was arrested in July on suspicion of possessing a destructive device after a search warrant was served at his home in Yucca Valley.
Lee was taken into custody after the July 4 search and released on bail two days later.
He was honorably discharged after that after seven years in the Marine Corps and subsequently moved his family to Alaska.
Corwin and her husband are from Oak Ridge, Tennessee.
