...Gideon is one of the "Lost Boys," a group of more than 400 teenagers — some as young as 13 — who authorities in Utah and Arizona say have fled or been driven out of the polygamous enclaves of Hildale, Utah, and Colorado City over the last four years.

His stated offenses: wearing short-sleeved shirts, listening to CDs and having a girlfriend. Other boys say they were booted out for going to movies, watching television and staying out past curfew.

Some say they were sometimes given as little as two hours' notice before being driven to St. George or nearby Hurricane, Utah, and left like unwanted pets along the road.

Authorities say the teens aren't really being expelled for what they watch or wear, but rather to reduce competition for women in places where men can have dozens of wives.

"It's a mathematical thing. If you are marrying all these girls to one man, what do you do with all the boys?" said Utah Atty. Gen. Mark Shurtleff, who has had boys in his office crying to see their mothers. "People have said to me: 'Why don't you prosecute the parents?' But the kids don't want their parents prosecuted; they want us to get the No. 1 bad guy — Warren Jeffs. He is chiefly responsible for kicking out these boys."

The 49-year-old Jeffs is the prophet, or leader, of the Fundamentalist Church of Jesus Christ of Latter-day Saints. The FLDS, as it is known, controls Hildale and Colorado City.

The sect, which broke from the Mormon Church more than a century ago, has between 10,000 and 15,000 members. It believes in "plural marriage," that a man must have at least three wives to reach the highest levels of heaven. The Mormon Church forbids polygamy and excommunicates those who practice it.
