The search for the pregnant wife of a U.S. Marine continued Monday, more than a week after she was last seen leaving her Twentynine Palms home.
At least 50 search and rescue crew members looked Sunday for 19-year-old Erin Corwin near Joshua Tree National Park, where investigators believe she was headed, said Cpl. Randy Naquin of the San Bernardino County Sheriff's Department.
But the search turned up empty.
"There is no end in sight until they actually find her," Naquin said.
Corwin, who is three months pregnant, was last seen about 7 a.m. June 28, leaving her home and heading toward the park.
When she did not return, her husband reported her disappearance the following day. Homicide detectives are investigating the case.
Investigators found her car June 30 in Twentynine Palms, but it was unclear where she was headed, the sheriff's department said in a statement.
Her mother, Lore Heavilin, told KESQ-TV she had planned to make a trip from Tennessee to Twentynine Palms to visit her daughter for her July 15 birthday and go to San Diego Zoo and Sea World.
Her parents apparently met with the lead investigator looking into her disappearance but provided them with no new information, according to the Locate Erin Facebook page created after she was reported missing.
But the investigator assured her parents "the physical search of the area is from sun up to sundown every day," according the Facebook page.
Hundreds of people from throughout the U.S. have posted Facebook messages of prayers for Corwin's safe return.
Community members reportedly shared ribbons and purple glow sticks to spread the word about her disappearance.
