"We are looking for a crime scene," says Capt. Leland Bolt from the San Bernardino County Sheriff's department.
Corwin, 19, who was about three weeks pregnant when she went missing, said good-bye to her husband, U.S. Marine Cpl. Jon Corwin, and left for Joshua Tree National Park at about 7 a.m. on June 28. She never returned.
On July 1, four search warrants were approved to search Erin's vehicle and home, and the vehicle and home of her neighbor, former U.S. Marine Christopher Lee, according to documents. The documents also stated there was probable cause that "a felony has been committed."
According to court documents filed at a Joshua Tree courthouse, Erin and Lee – who is also married – were having an affair and planned a special day together. They were going to celebrate Erin's pregnancy and he was "going to take her hunting," approximately two hours away at an undisclosed location.
Lee told officials, according to documents, that he went hunting in Joshua Tree National Park at about 7:30 a.m. June 28, but he was not with Erin. A search warrant was issued and Lee was arrested for possession of a destructive device, but was "not related to the disappearance."
Police continue searching for Erin. "Although suspicious circumstances have existed from the inception of this investigation there is still not enough evidence to rule out that Erin Corwin could be voluntarily missing," officials say.
