An Oakhurst woman was found unconscious on the side of the road near Bass Lake Saturday night. The Jeep she was driving still has not been located.

Now, Madera County Sheriff's Detectives are hoping the public can help them figure out what happened.

Detectives say 42-year-old Shanin Path was found lying on the side of Road 222, north of Road 274, shortly after 8:30 p.m. She was rushed to a hospital with severe injuries to her head.

According to the sheriff's office, Path was last seen driving her blue 2004 Jeep Wrangler in Ahwahnee at around 7 p.m. She was supposed to meet with friends for dinner in Oakhurst, but never showed up.

Detectives say Path's Jeep is similar to the one pictured above. The Jeep's California license plate is 5HOU133.
