A nationwide search is on for 20-year-old Marine Lance Corporal Maria Lauterbach, missing from Camp Lejeune in North Carolina since December 14, who is eight months pregnant and could give birth at any time.

Lauterbach, of Dayton, Ohio, was expected to testify about an incident she witnessed on base, according to her mother’s report to the police. She said she had begun to worry when her daughter stopped calling as she used to.

According to investigators and family members, Lauterbach disappeared on December 14 from the Camp Lejeune Base. Her mother reported her missing on December 19. Police investigators say that December 14 was the last day when the victim’s cell phone was used. The device was discovered on December 20 at the front gate of Camp Lejeune.

On the same December 14, a withdrawal from Lauterbach’s bank account was made the Marine Corp Times said. Moreover, ten days after her disappearance there was suspicious activity on her bank account, the authorities reported.

Lauterbach’s car, a Hyundai Sonata, was found Monday abandoned at a Jacksonville bus station, according to local media sources.

“There are several findings and pieces of evidence that have been discovered that cause law enforcement to be concerned with the circumstances surrounding Maria’s disappearance,” the sheriff’s department said according to the Associated Press.

Lauterbach’s friends have created a page on Facebook, called Help Us Find Maria, where people posted different comments and pictures, and which could be accessed by anyone who knows something about her.

"Call mom!!! You know the number," the page says. "All of us love you and we miss you. Please come home!" says a message on the page.

Lauterbach joined the Marine Corps on June 6, 2006 and was trained as a Personnel Clerk.

Sheriff Ed Brown offers a personal reward of $500 to anyone who tracks the girl.
