Four search warrants have been issued in the disappearance of a Marine's pregnant wife who has been missing for more than two weeks in California.
Meanwhile, a man who lives near the location where the missing woman's car was found told a local television station that he saw her rendezvous with a man in a red car the morning she disappeared.
Erin Corwin, who turned 20 on Tuesday and is three months pregnant, was last seen at 7 a.m. on Saturday, June 28, leaving her home on the base and heading for Joshua Tree National Park, her husband, Marine Cpl. Jonathan Corwin, told investigators.
Corwin reported his wife missing the next day. Police located her 2013 Toyota Corolla in the Twentynine Palms Marine Base on June 30, but have declined to say whether any potential evidence had been removed from the vehicle.
Authorities have obtained four search warrants in the case, two to search two vehicles, one of which is Corwin's car, and two apartments in Twentynine Palms.
The warrants, which all contained identical language allowing investigators to search for clues such as hair and fibers, DNA and electronic records, were signed by a judge on July 1, CBS8.com reported.
Michael Beasley, who lives near the location where Erin Corwin's abandoned car was found, told CBS8.com that the woman met a man at a nearby intersection and appeared to voluntarily enter his car before the two drove away.
“They were just sitting and chatting. If she wanted to get out of the car and say, ‘I don't want to be in this car,' she could have,” Beasley told the station. “When I came back a half hour later, just the (blue) car was sitting there. Next thing, I hear the weekend goes by and Monday morning the sheriffs are there looking for this girl because she ain't home yet."
Beasley described the man as shorter than 5-foot-9 and had short hair.
According to local media reports, Jonathan Corwin told investigators his wife -- a volunteer who worked with mistreated horses -- wanted to scout out the park in advance of a planned family visit. The Corwins are originally from Oak Ridge, Tenn., and Erin Corwin's mother had planned to visit her for her birthday in the coming weeks. Mother and daughter had already purchased tickets to visit SeaWorld, authorities said, and Erin Corwin had no known medical or psychological issues.
Corwin is described as 5 feet, 2 inches tall and 120 pounds, with brown hair and blue eyes.
