The officer turned to get confirmation but by the time he turned back to address the suspect, Ramos had already entered the west hallway unabated.
"In this instance, the UPD officer would have heard gunshots and/or reports of gunshots and observed an individual approaching the school building armed with a rifle.
A reasonable officer would conclude in this case, based upon the totality of the circumstances, that use of deadly force was warranted," said the assessment, from Texas State University's Advanced Law Enforcement Rapid Response Training.Thirty-two seconds after Ramos entered the school, he entered classroom 111.
"Immediately, children's screams could be heard along with numerous gunshots in the classrooms.
The rate of fire was initially very rapid then slowed, lasting only a few seconds," the assessment said.Five seconds later, the suspect exited the classroom, stepped into the hallway and then reentered 111.
"The suspect then re-enters what appears to be classroom 111 and continues to fire what is estimated to be over 100 rounds by 11:36:04, according to audio analysis.
Ramos was not neutralized until 12:50 p.m., ending in his shooting death, according to the report. »
