DETROIT, ORE., JULY 11 -- Searchers today found a missing 15-year-old girl from Fairfax County attending a leadership camp for deaf youths, and 18 others who had gone looking for her turned up a bit later.

Jennifer Phillips, of Vienna, was found in good condition in the Olallie Lake area 50 miles northeast of Detroit about 11 a.m., almost 24 hours after she was last seen, Marion County sheriff's Lt. Raul Ramirez said.

Phillips had some blisters on her feet but otherwise was all right, officials said. She was taken to Santiam Hospital in Stayton, Ore., for a checkup and a reunion with her parents, who flew in from Virginia when they learned of her disappearance. The parents described her as a bookworm and not an outdoor type.

Ramirez said searchers learned that 18 other campers and counselors attending the national leadership conference at Camp Taloali went looking for the missing teenager Tuesday and had not returned to camp. But they were found shortly before noon, he said.

"Everybody's okay," Ramirez said. "They didn't know she was found, so they were still out trying to find her."

Phillips was reported missing about 4:30 p.m. Tuesday, about six hours after she left Camp Taloali, one of two camps in the nation for deaf children. This is the first year the camp has played host to a national conference that teaches deaf youths survival skills.

The 4-foot-9-inch girl was wearing a tie-dyed shirt and white shorts and sandals when last seen about 10:30 a.m. as the campers were split in four groups for a hike around Olallie Lake on the Skyline Trail.

Phillips was among 52 teenagers nationwide chosen for the youth leadership camp, sponsored by the Junior National Association of the Deaf, part of the National Association of the Deaf in Silver Spring.

Three helicopters and several search groups looked for the girl Tuesday night.

Ramirez said 35 members of the sheriff's office were involved in today's search, including a Jeep patrol, mounted posse and two sign-language interpreters.
