The aerial search for Travis Decker slows as nearly three weeks pass since the discovery of three young girls’ bodies.

After more than two weeks searching the Central Washington state wilderness, authorities have yet to find and capture Travis Decker, the Wenatchee man wanted for the kidnapping and murder of his three young daughters.

"We're going to keep the pressure on," the Chelan County Sheriff told USA TODAY June 12 as he prepared to board a helicopter to help in the search.
