BAILEY, Colo. -- An estimated 5,000 motorcyclists rode in a caravan Saturday in honor of Emily Keyes, the teen who was shot at her high school by a gunman who held her hostage.

The motorcyclists, including Park County Sheriff Fred Wegener, rode 40 miles to Platte Canyon High School from the scene of the nation's worst school shooting in 1999 at Columbine High School in neighboring Jefferson County.

It was Wegener who made the call for SWAT officers to invade a classroom where authorities said Duane Morrison, 53, took Emily, 16, and other girls hostage and molested them Sept. 27. Morrison shot Emily in the head after SWAT officers stormed the classroom and then shot and killed himself. The other hostages survived.

On Saturday, bikers paid donations to be included in the benefit ride from Columbine to Bailey. The procession was so long that the first bikers, riding two abreast, pulled into Platte Canyon High School as the last bikers left Columbine.

Money collected from the ride will go to a fund to assist all the girls who were taken hostage.

Dan Patino, a local resident who came up with the idea for the ride shortly after the tragedy, said he was stunned with the turnout.

"This is not just about Bailey, and not just about Columbine. It's about every community," he said.

"There's not a lot to say," Emily's father, John-Michael Keyes, told the crowd. "This is amazing."

Local volunteers, working around-the-clock, helped Patino put the huge ride together in the course of a week.
