Spain: Technical setbacks slow search for boy in deep hole Spanish rescuers on the fourth day of a frantic race to reach a 2-year-old boy trapped in a borehole clung to hope of finding the toddler alive despite massive setbacks in getting to the bottom of the deep and narrow cavity

MADRID -- Spanish rescuers on the fourth day of a frantic race to reach a 2-year-old boy trapped in a borehole clung to hope of finding the toddler alive despite massive setbacks in getting to the bottom of the deep and narrow cavity.

The operation to rescue Julen Rosello from the shaft has gripped Spain since he fell into it Sunday during a family meal in the countryside northeast of Malaga.

Adults can't fit in the 110-meter (360-foot) deep, 25 centimeter-diameter (10-inch) hole and machinery hit an obstruction of hardened soil and a stone about two-thirds of the way down. Rescue teams have been unable to break through without endangering the child.

Maria Gamez, the Spanish government's representative in the Malaga province, vowed the search would continue until the boy is saved.

"We are not going to stop even one minute," Gamez said. "Nobody in the rescue team is putting in doubt that we will bring him out, and we all remain confident that he will be alive."

No vocal contact has been made with Julen. The only sign of him search-and-rescue teams have found so far is hair that matched his DNA. Officials think he might have slid under the obstruction that's blocking the way down.

The leading engineer in the search, Angel Garcia, said Thursday that creating an alternative access point involved days of digging work that normally would take months and technical surveying of terrains.

Garcia, head of the provincial civil engineers' association, told reporters at the site in Totalan, that workers will dig two parallel vertical tunnels. That plan came up after a horizontal hole bored in the past 24 hours from a hillside hit heavy stone.

The digging won't begin until at least early Friday so a platform for heavy machinery can be put in place, Garcia said. The engineer warned the work was "extremely difficult" and could be hampered by rain that is forecast for coming days.
