Security will be tight Thursday morning as classes resume for the first time since the deadly shooting at Platte Canyon High School.

Yesterday students were allowed to retrieve items left behind when 53-year-old Duane Morrison walked into the Bailey, Colorado school with a gun last week and took six girls hostage. School has been closed since the standoff, which left the gunman and 16-year-old hostage Emily Keyes dead.

Counselors will be on hand for students troubled by the return to the school, and the classroom where the bloodshed occurred will remain closed throughout the school year.

School Superintendent Jim Walpole says there were plenty of hugs and smiles yesterday as students returned briefly to the hallways. Everything, he says, went smoothly.
