Dozens of schools that closed as a precaution during the daylong manhunt planned to reopen Thursday with heightened security measures. The details of Pais' travel from Florida to Colorado began to trickle out Wednesday along with some classmates' confusion at her involvement. The student at Miami Beach High School dressed in black and kept mostly to herself, said Adam Charni, a senior at the school. Charni said he was "baffled" to learn she was the person authorities in Colorado were searching for. Frank DeAngelis, Columbine's principal at the time of the shooting, said he was on campus Tuesday when the threat prompted officials to lock the high school's doors.
