The missing hiker left her car in the parking lot of the Mountain Home Inn in Mill Valley. Authorities say a body believed to be hers was found just a half mile away.
Investigators say Sanner of Mill Valley was an experienced hiker on Mt. Tam.
Search and rescue teams found a body matching her description Thursday afternoon in a drainage creek about 120 yards up Panoramic Highway near the Matt Davis Trail. Investigators say she had been hiking with a male friend on Wednesday, but left him to go to her car as it was it getting dark.
"She may have possibly fallen, maybe 40-50 feet down into the drainage which sadly is covered with large rocks and boulders and so forth," said Marin Co. Sheriff's Lt. Doug Pittman.
The coroner will determine the cause of death and perhaps whether foul play was involved, but investigators say at this point there appears to be no evidence of anything suspicious. They also say there appears to be no connection to the case of another missing hiker found Saturday.
Search and rescue teams found the body of 33-year-old Magdalena Glinkowski of Menlo Park about a half mile from where they made Thursday's discovery.
"Right now, we haven't identified anything criminal in either one of these cases that would associate one with the other," said Pittman.
But not everyone's convinced. People who regularly ride and hike on Mt. Tam can't help but wonder.
"I've been riding up here for years and to have two people missing in less than a week is very strange," said Steve Stenberg, a mountain biker.
"Well if they find one more than I'll definitely think it's weird. Yeah, yeah," said Doug Moore, a hiker.
Investigators hope to have more answers soon, but until then, they say making a link would be pure speculation.
