Andrew Pollack, the father of murdered Marjory Stoneman Douglas High School student Meadow Pollack, told Neil Cavuto he is suing a Broward County Sheriff's Deputy for wrongful death in the aftermath of the February 14 mass shooting.

Cavuto said he also reached out to Peterson's attorney for comment prior to Pollack's interview.

Pollack said he is working with Gov. Rick Scott (R-Fla.) and others on a "commission" in the aftermath of the shooting, and that it is "brutal" to review evidence from the day his daughter was killed.

He said he is taking all of these actions because of his "immeasurable love" for Meadow, adding that her memory is "empowering" him to fight for her.

Pollack refused to refer to the shooter by name, instead calling him "18-1958" -- his criminal case identification number.

"This deputy (Peterson) was driven to that door [of the school] on a golf cart and at that time, 18-1958... was on the first floor," he said.

Pollack said the evidence shows Peterson "retreated" behind a wall and "allow[ed] 18-1958 to go up to the third floor where he shoots my daughter four times."

Pollack said his daughter was killed while trying in vain to protect another student named Kara. 

"18-1958 stalks down the hallway and shoots my daughter another five times [as she is] praying someone's going to help her," Pollack said. "That's why I'm doing this. I want to expose the incompetence... of what this deputy did."

Pollack said reports that the deputy's lawyer claimed Peterson heard the shots coming from outside the school is an "outright lie."

"They have him on the radio saying the shots are coming from [inside]," Pollack said. "How can he live with himself?"

Pollack said the suit includes several mental health authorities as well as James and Kimberly Snead, the couple who took in the shooter after his mother died, and the late mother's estate.

He said the case is "not about money" and that his ex-wife and surviving children can have any awarded funds.
