Terror in the Columbine Cafeteria

CCTV captured the shooters' chilling movements during the massacre.

Security cameras inside Columbine High School recorded Eric Harris and Dylan Klebold as they carried out their 1999 massacre. The silent, grainy footage from the cafeteria shows the shooters planting bombs (which failed to detonate) and later firing at students, providing a haunting and crucial record of the tragedy.
