BSO releases reports on its response to Parkland shooting.

At least three Broward Sheriff’s Office deputies arrived at Marjory Stoneman Douglas High School in time to hear gunshots but did not immediately enter the building where the shooting took place, according to reports they filed after the shooting. The officers said in their reports they were unsure where the gunfire was coming from.

“I then heard four-five very loud gunshots coming from what sounded like it was outside in the general area of the football field (east end) between me and where the other units were located to the east of me,” wrote Deputy Michael Kratz. “I took cover behind my marked unit and scanned for a gunman but was unable to locate one.”

The Broward Sheriff’s Office on Friday released firsthand reports filed by nine deputies who responded to the Feb. 14 shooting where 17 people were killed and another 17 were wounded.

Half of the 30 pages that were released in response to media requests were completely redacted. The Sheriff’s Office said the blacked-out pages included protected names of victims or witnesses. The documents are a fraction of the agency reports related to the incident.

The records show that an additional deputy who showed up early on the scene did not hear gunshots but crouched behind a police car until he saw

other officers approaching and followed them.

“I took a cover position behind my patrol car in order to quickly assess the situation and see if I could determine where on the school grounds this was happening,” wrote Deputy William Hanks.

Jermaine Johnson, a deputy coming from Tamarac, did not cite any uncertainty.

He drove to the scene, put on a bulletproof vest, grabbed his rifle, and “ran toward the east door of ” the 1200 building, where the shooting took place, according to his report.

He entered along with another deputy and several Coral Springs officers. They then searched for the shooter and helped move victims out of the building before the Sheriff’s Office SWAT team arrived.

The Sheriff’s Office, which serves the city of Parkland where the school is, has been criticized for its handling of the shooting response.

Scot Peterson, the school’s resource officer who was first on the scene, did not go into the building to confront the gunman because he was unsure of where the shooter was. He resigned.

A Sheriff’s Office timeline shows other deputies initially tried to enter the wrong building.

Coral Springs officers were the first inside the 1200 building, according to the timeline. The initial 911 calls, which described people shot in classrooms, went to Coral Springs emergency dispatch.

The Florida Department of Law Enforcement, at the direction of Gov. Rick Scott, is investigating the law enforcement response to the shooting.

Sheriff Scott Israel, reached by the South Florida Sun Sentinel on Friday, declined to discuss the narratives written by his deputies, saying he’s awaiting FDLE’s report before commenting publicly.

Israel told the Sun Sentinel on Feb. 23 that his agency was investigating claims from Coral Springs officers that some deputies did not go into the building.

On Friday, Israel’s press spokeswoman said that internal review is ongoing, but she could not say which deputies were under investigation or how many.

The shooting began at 2:21 p.m., according to the Sheriff’s Office timeline. It does not show an officer entering the building until 11 minutes later.

More than 70 Republican state lawmakers have asked the governor to suspend Israel, who is a Democrat.
