Nearly three weeks after the bodies of three young girls were discovered at a remote campground west of Leavenworth, the once-intense search for their father and suspected killer, Travis Decker, appears to have slowed its fervent pace.

Chelan County Sheriff Mike Morrison said police officials hope Decker soon runs out of supplies, surfaces and makes some kind of bold move that gets him caught.

Law enforcement will be embracing "a change in tactics" while searching for the Wenatchee father accused of kidnapping and murdering his three daughters earlier this month.
