The victim was identified as 23-year-old Marie Flores of Perris.
Authorities say the gruesome discovery was made near Alabama Street, just south of Almond Avenue, at about 6:30 p.m. A woman said she was on her usual walk along the orange groves when she found the body.
"I poked around a little bit with a branch ... I even called out ma'am," said Sharon Polich of Redlands. "It wasn't moving or nothing, so that's why I called 911."
At the time, she says she didn't know if the woman was dead or alive.
Police are only saying that the body was dumped, but they're not entirely sure that the murder happened somewhere else. A piece of plastic covered the body, but it was unclear if authorities found the body that way, or if they placed the plastic over the body.
Anyone with information is urged to call the Redlands Police Department at (909) 798-7580.
