MARINA, Calif. - A California woman’s body was in a busy parking lot for more than three months before someone noticed something was amiss and reported the vehicle to investigators.

22-year-old Lauren Moss, of Marina, California, was found dead inside of her parked Volkswagen Jetta just last week. The car was found parked outside a Walmart store in Salinas, California.

Moss was last seen alive on Nov. 13, the same day that she left a drug rehab center. Someone reported the woman missing to police at the time, and Seaside PD had an open missing person case.

Moss’ body was discovered by Walmart employees on Feb. 3.

Police said the woman’s vehicle had dark-tinted windows, and a sunshade was covering the dashboard making it difficult for anyone to see inside the car.

While her cause of death has yet to be determined by the coroner, police officers believe Moss’ death was possibly a suicide. A drug needle was located in the vehicle by authorities.

A Walmart spokesperson said they don’t have personnel patrolling overnight, but 24-hour surveillance cameras are installed at the site. When police looked through the security footage, they found the footage was only stored as far back as Dec. 2015. The footage from December showed the Jetta parked in the same spot.
