MISSION VIEJO, Calif. (KABC) -- A woman's body was found behind a bank in Mission Viejo on Thursday afternoon, prompting an investigation in which authorities have deemed her death suspicious.A 911 caller reported the grim discovery at about 3:15 p.m. in the brush behind a U.S. Bank branch in the 25000 block of Muirlands Boulevard, according to the Orange County Sheriff's Department. A civilian found the slightly decomposed body covered in a blanket at the location, just off the 5 Freeway near La Paz Road.The deceased woman was not immediately identified, and it was unclear if she died at the scene.A groundskeeper said the body was not there before Nov. 5, the last time crews tended the landscape outside the bank.Judy Paskey, who co-owns a nearby salon, was astonished when she learned of the incident."The weather's been hot and I can't imagine," she said. "I mean, we walk up here every day to dump our trash. If there was a body there I would think you would have smelled it."An autopsy is pending to determine the cause of death.
