MOAB -- Paragliders joined a search Saturday for a Moab skydiving instructor missing more than a week.
Three men flew motorized paragliders along a ridgeline behind David Brown's home and plan to continue looking for him today if the weather permits, said family friend Micaelo Choo.
Searchers using dogs also looked for Brown, 37, who was last seen June 29
by his boss and a friend as he walked into his trailer. He stayed at the home of the skydiving school's owner.
"It's been a very difficult day," Brown's sister, Wendi Tekamp, said Saturday, "but we are grateful for the generosity of those who searched today for Dave."
It's uncharacteristic of Brown to vanish without a trace, she said.
Friends said he wasn't planning a trip and that he left behind all his belongings, including money. They also said his disappearance isn't related to skydiving.
Police said there were no signs of foul play, and they have few leads.
"I'll keep going until there's nothing else to follow," Moab Police Chief Mike Navarre said. "We don't have hardly any leads in this case, but once in a while, something pops up."
Brown, a native of Dartmouth, Nova Scotia, has been living in the United States for about a decade, Choo said. He moved to Moab two months ago and taught at Skydive Moab.
His friends initially thought he might be visiting his girlfriend in Las Vegas, but Tekamp said that Brown's girlfriend returned to Moab from Sweden on Thursday to help with the search.
The police have briefed the family and are baffled about where he has gone.
"It's anybody's guess," Choo said. "We're still hopeful of finding him alive."
