Parents of victims of the Parkland mass shooting are angry and demanding answers after a bombshell report revealed details about a “disturbing assault” at the school.

Four years to the day before the February mass shooting at Marjory Stoneman Douglas High School, the son of Broward County Sheriff Scott Israel was reportedly involved in an incident that was allegedly “covered up” by Officer Scot Peterson, the school resource officer who did not enter the building to confront Nikolas Cruz as he killed students and teachers in the tragic shooting, WPLG reported.

Two 17-year-old students at the school allegedly bullied a 14-year-old freshman boy in the incident, WPLG Local 10 investigative reporter Bob Norman reported Thursday. The victim was allegedly held down by one of the 17-year-olds while the other kicked him, grabbed his genitals and shoved the boy’s baseball bat against his buttocks “simulating rape” through his clothes.

Royer Borges, the father of a survivor of the Parkland shooting, is now calling for the 2014 case to be investigated since the sheriff’s son and another boy only received a three-day suspension in what the police report, written by Peterson, described as a “simple battery” rather than sexual assault which would have led to a greater penalty.

“Allowing the deputy to reduce a sexual assault to simple battery was disgusting and should have never been permitted. Maybe if deputy Peterson would have been made to answer for this he may have been replaced by a more competent deputy but it was not done and the two individuals were charged with a simple battery,” Borges said in a statement issued through his Fort Lauderdale attorney’s office, according to Patch.com.

Peterson’s report indicated that the victim’s parents did not request “any law enforcement action regarding the above incident,” and that the “school district disciplinary matrix requires no law enforcement action required regarding the above incident,”

“Now I ask you: If this wouldn’t have been the sheriff’s son, would a sexual assault have been reduced to a simple battery? Was deputy Peterson allowed to retire with his pension because he protected Sheriff Israel’s son from having a felony arrest,” Borges asked. “These are the questions that I and I’m sure many people from this county want answered.”

Borges, whose son is still confined to a wheelchair because of injuries from the mass shooting, wants Florida Gov. Rick Scott to investigate the matter. The family filed the first lawsuit against Cruz in April and has other lawsuits as well. They also planned to file a separate lawsuit against the Broward County school system and sheriff’s office, according to Patch.com.
