It was Monday, August 8, 2005 when 64-year-old Nita Mayo traveled over Sonora Pass. Last seen at the Strawberry General Store near Pinecrest, California, the nurse didn’t return to her job at Mt. Grant General Hospital, in Hawthorne, Nevada, the following day.
Alarmed, her co-workers contacted the Mineral County, Nevada, Sheriff’s Office and reported her uncharacteristic absence. Both Tuolumne and Mono County, California, Sheriff’s Offices were also notified.
Nita’s car would be seen by a Caltrans employee at Donnell Vista that Monday night and again Tuesday morning. But he didn’t think much about the car, as backpackers also use the point for overnight parking.
On Wednesday evening a Tuolumne County sheriff’s sergeant realized Nita’s 1997 Mercury Sable station wagon was still at the vista. Inside her locked car were souvenirs from the store, her purse, wallet, glasses and car keys. Only her camera and prescription sunglasses were missing.
Search dogs were brought in, but no scent of Nita was picked up. Further searches of the area also failed to locate any evidence of her.
In September 2005 Tuolumne County Sheriff’s investigators named Jewel Rice of Colorado Springs, Colorado as person of interest in Nita’s disappearance. She’s believed to have been in the Strawberry and Donnell Vista areas around the same time, asking for help after her vehicle broke down.
Jewel left Sonora without her car on August 12 and current whereabouts remain unknown.
Nita’s not the only person to be reported missing from Donnell Vista on California’s State Route 108. Forty-six-year-old Patricia Tolhurst vanished from the vista in 2014.
On April 20, Patricia mailed a letter to friends letting them know that she would be hiking in the area of Donnell Vista. She also sent two audiotapes to a friend telling him her life story.
Two days later, her white Toyota 4-Runner, with its sun-roof still open would be found abandoned with her keys, purse and identification inside. Search and rescue teams found no nearby clues leading to the mother of two.
Then sometime before October 3, 2016, 68-year-old Breck Phelps vanished along with his fishing gear
and cellphone, from Donnell Vista. His car, a red 2007 Nissan Versa, was found a quarter-mile away near a trail leading to the Stanislaus River.
After four-days of searching by teams that included the California Rescue Dog Association, Monterey Bay Search Dogs and the National Guard, no sign of Breck, a corrections officer at the Sierra Conservation Center, near Jamestown, California, was found.
Finally, 20-year-old Humboldt State University student and future forest ranger, Michael Madden went missing from his campsite at Sand Bar Flat, 25-miles south-east of Donnell Vista around August 10, 1996 with his dog, Matilda. Four days later, Matilda would wobble into camp, worn-out and severely dehydrated.
Two days later, friends went looking for Michael only to find a freshly build fire and Joseph Tine using Michael’s registered campsite. He was carrying an automatic pistol and asked the friends if they were looking for “Mikey.”
Over the next six-hours Tine is said to have repeatedly cocked this pistol as the group waited for Michael to return. Tine was given a polygraph nine months after Michael vanished, however the results have never been released and he’s never been charged.
Investigators say that they believe Michael met with foul play. Included in this theory is a possible run-in with Cary Stayner, who was convicted in 2002 of murders of the Carole Sund, her teenage daughter Juli Sund, also from Humboldt County, California and their teenage traveling companion Silvina Pelosso as well as Yosemite Institute naturalist Joie Armstrong.
