Reward in Search for Missing Oregon Boy Doubles

PORTLAND, Ore.  -- The mother of an Oregon boy missing for 53 days tearfully told her son not to give up hope, while investigators doubled the reward for information leading to his whereabouts.

The Multnomah County Sheriff's Department says "significant progress" is being made in the search for 7-year-old Kyron Horman but declines to offer details. The $25,000 reward has been increased to $50,000.

At a news conference Tuesday afternoon, Desiree Young broke down while addressing her son, sobbing: "We are all coming to get you to bring you home."

Kyron vanished June 4 after attending a science fair at Skyline Elementary School in northwest Portland. The case has taken many twists in the weeks since, many of them centered on stepmother Terri Horman.
