DUNKARD, Pa. -- The FBI yesterday printed 8 1/2-by-11 fliers, in full color and high resolution, listing everything it knew about Gabrielle Miranda Bechen, missing four days now. She stands 4-foot-9. She weighs 77 pounds. On Tuesday morning, she dressed herself in a black shirt and tan shorts and hopped on a low-powered ATV with fire stickers atop each tire.

Then, for reasons still unknown, she disappeared.

The days since -- including another 120-person search yesterday through the thick woods near Gabrielle's remote Greene County home -- have yielded few helpful clues. Day 3 of searching ended without evidence of Gabrielle's ATV, without suggestions of her whereabouts and with a lingering fear that she may not be in the woods at all.

Faced with the demoralizing status quo, those involved clung to the few new developments -- the fliers, for example, fresh off the printer, a handful of which Marsha Presock grabbed just after 1 p.m.

Ms. Presock, a close relative of the Bechen family, trekked up the dirt road and told a group of somber friends and family about her plans. She'd post the fliers everywhere, she said. On trees. In Greensboro. In Bobtown. Later, Ms. Presock promised, she'd deliver burgers and hot dogs to Gabrielle's parents, Blanche and Christopher.

Until big news interrupted, searchers and friends passed time by concentrating on details.

In the morning, organizers formed 19 separate search teams, each between two and 10 people, equipping them with compasses and small area maps. They focused on two areas: the densely wooded mile closest to the Bechen trailer home -- located at the end of Presock Road -- and any connecting paths on which she could have ridden her ATV. "A two-pronged approach," said Steve Weiss, the search organizer from the Appalachian Search and Rescue Conference.

Mr. Weiss encountered a few problems, though. He'd never led a search this large. In most areas of the wilderness, trees grew so thick that searchers were forced to move slowly. He knew the statistics -- that most missing 12-year-olds on foot stayed within a mile of their disappearance point -- but the ATV complicated matters. Some speculated that Gabrielle could have traveled up to 30 miles on her quad, even with one gallon of gas in its tank. Others said the quad, within the dense forest, would have struggled to move whatsoever.

"It would be quite a struggle, if at all possible," to move on the ATV, state Trooper Joseph Christy said.

The family living at the top of Presock Road -- roughly 1,000 yards from the Bechen house -- said Gabrielle would frequently ride her ATV up the dirt street, only to get stuck on small divots.

"She really liked to ride ATVs," said Michael Gibbs, 13. Then the soon-to-be-seventh grader paused. "Well," he said, "I guess everybody knows that by now."

More troubling were the uncertainties and dead ends. A day earlier, Gabrielle's parents hinted she may have left with a backpack; then they found it inside their home. Though Gabrielle had a cell phone, it was not activated -- thus preventing police from tracking it. The family's computer, seized by police, produced no clues. Similarly, officials have found no clues of family trouble that may have prompted the disappearance.

Trooper Christy played down FBI involvement, saying simply that federal officials could deliver resources local officials could not. "They do this all the time," Trooper Christy said. "So as far as setting up computer stations, bringing in additional phone lines, if you need Internet capability, setting up routers, they have these items available to them. Fancy fliers. We can do black and white, but they can do color."

The FBI also helped set up a hot line (1-800-CALL-FBI), available for tips. So far, Trooper Christy said, Gabrielle's disappearance could be traced to one of three possibilities: Either she crashed her ATV, ran away or was abducted.

Though days of empty searching has brought attention to the latter two options, Mr. Weiss promised volunteers would scour the forest for at least one more day. Local support had yet to taper, he said, but searches for Sunday and beyond were still in question. If evidence hinted at an abduction, Trooper Christy said, the FBI would already be up to speed -- another advantage of its involvement.

Meanwhile, searchers were clinging to the possibility that Gabrielle is in the wilderness, usually an attraction for deer and turkey hunters. Yesterday, almost 100 vehicles lined the grassy field near the Bechen house. Volunteers, upon leaving, waited for the next directions about today's search.

"The ends of searches are often the hardest," Mr. Weiss said. "We're now running up against the possibility she was hurt. We're running up against the possibility of dehydration. We go on the hopes that we can find her alive."
