    PLEASANT GROVE -- An hour after his rescue Wednesday from the trunk of his family's car -- where he was trapped for more than 20 hours -- 5-year-old Zachary Furner was ready to run and hide again.
    As family, friends and some of the hundreds of volunteers who helped search for the autistic boy celebrated in the front yard of his home, Zachary smiled in his mother's arms, holding a videotape of "Jurassic Park," his favorite movie. But when Dawn Furner set the barefoot boy down, he ran toward a neighbor's back yard.
    "He just doesn't like big crowds," father Loren Furner said as his wife and Zachary's grandfather chased the fleeing boy. "He'll run away."
    Zachary, who doesn't speak and likes to hide in confined places, had disappeared several times before, but always was quickly found -- usually in an orchard about a half block from the home he shares with three brothers, ages 7, 2 and 5 months.
    On Tuesday night, however, his family called police when they could not find him after he disappeared from their back yard around 5 p.m.
    During an initial search of the home, "we specifically asked if [the Furners] searched the trunk," said Pleasant Grove Lt. Clark Nielsen. In an apparent miscommunication, police believed the trunk had been searched.
    Loren Furner said he had heard the inside front and back of the maroon Pontiac Grand Am were examined, but the trunk apparently was never opened.
    Police searched the house at least three more times. Investigators also called in off-duty officers, search and rescue teams, K-9 units, city employees and volunteers to search the neighborhood and nearby fields. Police estimated more than 800 volunteers scoured a 3-square-mile area of fields, orchards and canals.
    While the search continued, the family's car was driven at least four times -- twice by each parent. It was parked in a heated garage Tuesday night, then on the street Wednesday after Dawn Furner drove it to the police station. Over the two days, hundreds of people walked by the car.
    But at 1:40 p.m., Laura Deichman, a Payson woman helping with the search, heard a child quietly crying as she walked by the family house.
    Dawn Furner came out to open the trunk and was stunned to find Zachary, who retreated deeper inside when the crowd gave a loud cheer.
    "It's just amazing I could make a difference," Deichman said.
    Volunteer Jerry Duclos, who had searched a nearby junkyard filled with cars earlier in the day, helped pull Zachary out.
    "He was soaked with sweat," Duclos said. "His face was red."
    Dawn Furner ran Zachary into the house and gave him a glass of water. Paramedics determined Furner didn't need to be taken to the hospital but recommended his parents take him to the family doctor.
    "I can't believe he's been in the trunk for 20 hours," Dawn Furner said. "I never heard a sound. I even turned the radio off so I could say a prayer."
    The parents believe Zachary must have gone into their garage from the back yard, pulled a lever inside the car to open the trunk, then walked around the rear of the car to climb inside.
    Shortly before Deichman's discovery, the Furners had begun playing Zachary's favorite Disney songs out a window, hoping it would lure him home. It was that music, Loren Furner believes, that prompted the boy to begin crying so Deichman could hear him.
    A relieved Dawn Furner joked, "I decided to lock him into his bedroom for the rest of his life."
