Foxnews.com -- (2/22/2018) The sheriff's deputy who was on patrol at Marjory Stoneman Douglas High School in Parkland, Florida, on Feb. 14 resigned Thursday after video surveillance showed he never entered the school, even though he "clearly" knew there was a shooting taking place, officials said.
Deputy Scott Peterson, of the Broward County Sheriff’s Office, was stationed on the school’s campus when Nikolas Cruz opened fire with an AR-15 rifle, leaving 17 people dead and others wounded.
Sheriff Scott Israel during a press conference Thursday said video showed Peterson arriving at the west side of the building where the shooting took place. Peterson, Israel said, took up a position but "never went in."
Peterson was armed and in uniform during the shooting, but never entered the building despite "clearly" knowing a shooting was happening, Israel said.
The sheriff said he believes Peterson remained outside of the building for four minutes, while the shooting in total lasted six minutes. Israel said the officer never fired his weapon.
Israel said he's "devastated. Sick to my stomach. There are no words."
When asked about what law enforcement agencies entered the building first, and at what time, Israel said that it "doesn't matter who went in first" or "what order you went in."
"What matters is that when we, in law enforcement, arrive at an active shooter, we go in and address the target," the sheriff said. "And that’s what should’ve been done."
Peterson, according to Israel, should've "went in. Address the killer. Kill the killer."
The sheriff said that he suspended Peterson without pay pending an internal investigation, but the officer resigned and retired.
In 2014, Peterson was named School Resource Officer of the Year in Parkland, WSVN reported. The district stated "Deputy Peterson has proven to be reliable in handling issues with tact and judgment.”
Two other deputies from the Broward County Sheriff's Office have been placed on restrictive duty as officials investigate "whether or not they could have done more, should’ve done more."
The officers were identified by WSVN as Edward Eason and Guntis Treijis.
Their restricted assignments come as the bureau found it responded to 23 calls regarding Cruz or his brother since 2008. In two of the instances, Col. Jack Dale said, protocol might not have been followed.
Israel said an investigation remains ongoing.
