During the Feb. 14 attack, the unarmed Medina said he saw Cruz exit an Uber and enter the campus carrying a black bag, but did not confront him or lock down the school. At the time, Cruz had been expelled from the school and banned from being on campus.

Medina reportedly said that when he saw the mass shooting suspect seemingly “beelining” for the 1200 building — the location where the shooting, which killed 15 students and 2 adults, unfolded — he warned other campus security guards, but did nothing to stop him.

One of them, Taylor, then reportedly hid in a janitor’s closet as Cruz opened fire.
