SCOTTS VALLEY -- A Scotts Valley man who went missing Wednesday night was found safe in Salt Lake City on Friday after a man he was traveling with notified authorities.
Matthew Abraham, a 20-year-old high school cross-country coach and former Cabrillo College student, suffered a head injury March 8 from a mountain bike fall that left him "not in his right mind," said his father, Bill Abraham.
It was not clear why he traveled to Utah, although he has family there, deputies said.
"He's just an amazing kid," said family friend Becky Foy. "I hope they can get him home as soon as possible."
A Santa Cruz County Search and Rescue Team searched for Abraham around Scotts Valley and other areas Thursday. Santa Cruz County sheriff's deputies also distributed his picture and description.
Friday morning, a long-distance bus driver told authorities that she saw Abraham on a bus she drove from San Francisco to Sparks, Nev., on Thursday.
"It was an odd tip to follow up on," said sheriff's Lt. Steve Carney, but they did and retrieved surveillance images from a gas station where the bus let off passengers in Sparks.
They worked with Sparks police Friday to get the images to Abraham's parents, who identified him in part by a rainbow-colored teddy bear that he had on his backpack strap. The bear was missing from their house.
Late Friday afternoon, a man who had traveled with Abraham from San Francisco realized that Abraham was missing. They were at a library in Salt Lake City when he called authorities, Carney said.
Abraham's family said they did not know the man, and it's unclear how long Abraham knew him, deputies said.
Abraham is expected to remain in the protective custody of Salt Lake City police, but they could only hold him for a short time because he is an adult, Carney said.
Bill Abraham's uncle lives in Salt Lake City and he or another family member planned to pick up Matthew.
Members of Abraham's family flew and drove to Utah on Friday night.
"It's all been really shocking for us," said Daniel Abraham, Matthew's older brother.
More than 25 Search and Rescue volunteers and four K-9s participated in the Scotts Valley search from Thursday morning to 1:30 a.m. Friday morning.
Abraham fell from a trestle about 50 feet on to sand at Henry Cowell Redwoods State Park. Abraham said he couldn't read or write since the fall -- which he couldn't remember -- so he posted a YouTube video Tuesday to thank his supporters.
"I'm having a lot of trouble with simple tasks, but supposedly it'll get easier and easier until I'm fully recovered," Abraham said in the video.
"But at the moment, it feels like someone has dug pliers into my skull, and they're trying to tear it open."
