Authorities think the woman was driven to the area overnight, shot once in the head and left to die on the side of the road.
Police arrived at the scene just after 2 a.m. Wednesday. A dark remote stretch of La Tuna Canyon was lit only by the lights of patrol cars as authorities responded to reports of a body found.
Detectives with the LAPD's Foothill Division say it was a 911 call put in by a passing motorist that led them to the scene. Police say they do have enough evidence to conclude the murder took place on the side of the road, just about a half mile from the 210 Freeway onramp.
Authorities say they have no witnesses yet and no suspect information. They've only released a description of the victim, who was found without identification. She's described as a heavy-set white woman in her 30s, but little else is known in the case.
"Because of the lack of other information and obviously being in a secluded area like this where we can't find any video, we're in a situation where we have to strive to get every piece of evidence we can off the ground and the surrounding areas. So that's what we've been doing all night," said Detective Pat Barron, LAPD.
As the investigation continues, detectives say the victim's fingerprints will be used to make a positive identification sometime Wednesday.
