He said Coral Springs dispatch received the initial 911 call and that their officers arrived at the school before his deputies.
A student at the Parkland, Fla., high school where 17 people were killed in a mass shooting last week defended the local officer who did not enter shooting scene.
The Coral Springs Police Department is the neighboring police department, and located about three minutes away from the school.
The sheriff said that he suspended Peterson without pay pending an inside examination, however the officer surrendered and resigned.
He said deputies who responded to two previous incidents before the shooting were being investigated to see whether the deputies could have done more and whether any policies were violated.
At a conference of conservative activists on Thursday near Washington, vice president Mike Pence said the administration would make school safety “our top national priority” after the shooting at the school in Parkland, Florida.
The Florida deputy who waited outside as a gunman targeted staff and students at Marjory Stoneman Douglas High School, killing 17, was twice nominated as the School Resource Deputy of the Year and won the award in 2014, personnel records obtained by CNN show.
But despite being armed, in uniform and at the school, Peterson, 54, never went inside throughout the shooting.
The video shows that Peterson remained outside the building for upward of four minutes during the shooting, which lasted about six minutes, Israel said. He then took up a position but “never went in”, officials said.
“Our main goal at this point, absent of helping these families heal and keeping our schools safe, is making sure this killer receives the justice he deserves”, Israel previously said.
The Broward County Sheriff’s Office received “thirdhand information” in February 2016 that Cruz “planned to shoot up the school” and posted Instagram pictures of guns, The Times reported.
The Broward County Sheriff’s Office did not respond to BuzzFeed News’ questions about the additional calls, or how it determined to include the 23 calls that were disclosed to the public, but not the others. It is also facing backlash for apparently mishandling some of the 18 tip-off calls related to the suspected shooter.
Two other deputies have been placed on restricted duty while BSO’s Internal Affairs investigates how they handled the two shooter warnings.
Coral Springs Police Chief Tony Pustizzi said the confusion stemmed from human error and a “communication failure”, not malfunctioning equipment.
We understand everything wasn’t done perfectly, and if it happened in Los Angeles or Chicago or any other city, every person wouldn’t have performed perfectly.
When officers arrived on the scene of the shooting, he said, they wanted to gain access to the security footage to learn what happened and where the perpetrator could be. He is being held in a Broward County jail.
