SAN DIEGO -- Police are deciding whether to search a second landfill in their investigation into the April disappearance of a 2-year-old boy.

The San Diego Police Department is weighing the costs and benefits of combing through trash and sewage sludge at the Otay landfill in Chula Vista for evidence that could help resolve the disappearance of Jahi Turner, Capt. Mike McCulloch said Monday.

Boy Has Been Missing For Two Months

In May, police and volunteers from the Navy and Marine Corps searched through 5,000 tons of trash at San Diego's Miramar landfill at a cost of $100,000. Authorities have not disclosed whether they found any useful evidence in the search.

Trash collected from the neighborhood where Jahi lived and from around the park where he was reported missing April 25 was sent to both Miramar and the Otay landfill. But police didn't search the Chula Vista dump because the presence of sewage sludge made it potentially dangerous for officers and volunteers, McCulloch said.

At the privately owned Otay landfill, searchers would have to comb through about 4,000 tons of trash and 400 tons of treated sludge from a wastewater treatment facility.

The city may hire a private contractor to search the Otay landfill, but the effort could cost about $1 million because of the presence of sewage, McCulloch said. The first search was also less expensive because police used donated equipment and volunteers.

"We're looking for any evidence," McCulloch said. "In the worst case scenario, maybe Jahi Turner's remains or any evidence that would lead to a suspect."

Jahi was reported missing from a playground in Balboa Park by his stepfather, Teiray Jones, who told police he left the boy alone to buy a soda from a nearby machine. The child's mother, an 18-year-old Navy sailor, was aboard the USS Rushmore at the time.

Investigators have declined to discuss the progress of the investigation or whether they have developed any suspects.
