With the draining of Meyers Lake -- where the girls' bikes were found last Friday afternoon -- taking longer than anticipated, the FBI today launched a dive team from Los Angeles to help. The team is expected to arrive Thursday.
On Tuesday, Abben confirmed that bloodhounds brought in by federal investigators picked up the girls' scent near the nature trail where their bikes were found.
In addition to the lake search, authorities directed the local waste pick-up company to separate trash from Evansdale from trash from other areas when it is dumped at the landfill.
"That is what our drivers were asked to do: Any trash from Evansdale be put in a segregated area of the Black Hawk County landfill," Debbie Acklin, a spokeswoman for Black Hawk County Waste Disposal, told ABC News. "When they get to the landfill, they're to say where the load is from and told where to put it."
