Chicago Tribune "As gunman Nikolas Cruz skulked through Stoneman Douglas High School on Feb. 14, a person’s chances of surviving depended largely on where they encountered him.
"One student who came across him on the first floor got away as Cruz loaded his weapon, according to a chilling animation released Tuesday. And all students on the second floor survived. But students and staff on the first and third floors were at Cruz’s mercy, the animation shows.
"The rudimentary video, made by investigators from the Broward Sheriff’s Office, provides the first official account of Cruz’s movements during approximately six minutes and 45 seconds he spent inside the school building. It was played at Tuesday’s first meeting of the state-appointed commission investigating “system failures” related to the Parkland school mass shooting.
"The animation shows Cruz — as a black dot with a line representing the AR-15 rifle he carried — methodically stalking through the building and shooting his victims — students are shown as green dots and school staff as blue dots. As bullets strike each person, the color of the dot that represents them changes to purple for the dead and yellow for the injured." . . .
Timeline of the shooter's actions
"Gunman Nikolas Cruz prowled the halls of Marjory Stoneman Douglas High School for six horrible minutes – a flash of terror where life and death became a matter of chance. Interviews, police reports, audio recordings and other records provide 2:19 p.m.
"It is a half hour before roughly 3,500 students and staff are set to stream out of their high school in Parkland. Love and thoughts of dates with sweethearts fill their heads this Valentine’s Day as the clock slowly ticked toward dismissal.
