Colorado teachers flooded into the state Capitol to press for better protections for students and school staff after a 17-year-old Denver student shot two administrators, fled to the mountains and killed himself.

Outraged Denver students and parents are demanding better school security and pushing for tighter firearm controls Thursday, a day after a 17-year-old student shot and wounded two administrators at a city high school beset with violence.

A sheriff said that a body was found Wednesday night during a search in the Colorado woods near where they had found an abandoned car that belonged to a 17-year-old student accused of shooting two administrators at his Denver high school earlier in the day.
