Pete Davidson's family pays tribute to firefighter dad killed on 9/11

Pete Davidson's sister has posted a tribute to her late dad Scott, 21 years after he was killed in the 9/11 attacks in New York.

Scott Davidson died on 9/11 at age 33. He was one of the New York firefighters and had been dispatched to the World Trade Centre after a second hijacked plane hit the south tower.

Pete Davidson was seven and his younger sister Casey was three-years-old when their father died trying to save the lives of his fellow New Yorkers.

Casey, 25, paid tribute to her hero dad with a social media post of the elder Davidson clad in his New York City Fire Department uniform.

"This year more than ever I wish you could be here," the caption read. "We miss you, we celebrate you and we remember you every day. Proud to be your Caseygirl."

Pete, who currently is taking a break from social media, has therefore not posted anything to social media.

On the morning of September 11, 2001, Scott Davidson was one of six firefighters who raced across the Brooklyn Bridge to assist those trapped after the second plane hit the twin towers.

The six firefighters were last seen running up the stairs of the Marriott World Trade Centre

Hotel to save terrified guests, the New York Post reports.

The hotel was destroyed when the towers collapsed.

According to the National Fallen Firefighters Foundation, the Staten Island father’s lifelong dream was to be a firefighter, as per the New York Post.

His obituary on the foundation's website reads that his 'acts of heroism [were] not surprising'.

The loss had a huge impact on the Davidson family.

In 2019, the comedian told The New York Times that it was an 'overwhelming' tragedy.

Pete's film, The King Of Staten Island, also details his loss and his journey dealing with the death of his father. 

"It’s [as] transparent as I could be,” Pete told E! News about the film.

"We really wanted to follow this family and tragedy and how it affected them. And we wanted to show how you could overcome tragedy through life experiences."

The SNL star revealed making The King Of Staten Island helped him work through issues that remained following his father's death.

"I think when you’re able to share a story like this at this magnitude and with so many people, it really allowed me to be as open and honest as I could be, and it helped me deal with a lot of my personal demons," he told E! News.

"This was something, one of the goals for this film was to allow me to put my past behind me, and I think we were able to do that."
