The search continues for Isaiah Eli Marsh, 30, a Nevada County man missing since about April 14.
On Friday, friends and family searched the North San Juan and Yuba County areas. Search and Rescue volunteers were out combing the Bullard's Bar area on Thursday, said brother Narayan Marsh.
"Some of his friends got together, and got a helicopter out " they flew the whole area from Bullard's Bar to North San Juan," Narayan Marsh said Friday. "They didn't see anything."
A signal from Isaiah Marsh's cell phone was last picked up by a tower at Bullard's Bar, so searchers were concentrating on that area, his brother said.
As of 9:30 p.m. Friday, Marsh had not been found, Nevada County Undersheriff Richard Kimball said. Searchers were continuing to follow leads through the night Friday and planned to work all weekend on the case, he added.
"Something's really wrong," Narayan Marsh said. "We're all really worried."
Marsh's friends became concerned on Saturday after he failed to return telephone calls, said friend Sara Wilkins.
"It's not like him to take off," Wilkins said. "He always takes his phone charger with him, and both his cell phones have been off since (April 14)."
"He is known to be very reliable ... He communicates often with friends about his plans and is not a spontaneous person," wrote friend Kali Littlewing in an e-mail. "He has missed important appointments and events he had wanted to go to. His home looks like he never intended to go away for a trip ... His toothbrush, daily planner and important medication for his shoulder were still at home."
Marsh is described as a white man, 5-feet-10-inches tall, weighing about 220 pounds, with blond hair and blue eyes. Also missing is his truck, a black 2003 Ford F350 dually with California license plate 8J41251.
"We've exhausted what few leads we had," said Nevada County sheriff's Lt. John Kropp. "We're hoping to have the California Highway Patrol helicopter do an air search Monday or Tuesday, depending on their availability."
Anyone with information regarding his whereabouts is encouraged to call the Major Crimes Unit at 265-1263.
