Megyn Kelly is mourning the death of her sister, Suzanne Crossley, after she died unexpectedly in Upstate New York.

“Something really sad happened in my family over the weekend,” Kelly said Monday on “The Megyn Kelly Show” on SiriusXM.

“My sister died, she was 58, her name was Suzanne Crossley, and she died suddenly on Friday of a heart attack.”

Kelly said Crossley hadn’t been in good health over the past few years with “sort of one problem after another,” but the death was still “sudden and unexpected.”

She said she traveled to Delmar, N.Y., to be with her mother, her brother Paul and Crossley’s son after hearing the sad news Friday.

“It was really hard, it was extremely emotional,” Kelly added. “My poor mom, as all moms and dads out there know, this is not the order this is supposed to happen.”

Kelly, 51, said she was planning to head back to the Albany area for her sister’s funeral on Tuesday.

According to her obituary, Crossley was born in Nyack and grew up in Syracuse and Albany; the family lived in the Jamesville-DeWitt school district until moving to the Capital Region when Kelly was 9 years old and Crossley would have been 16.

Crossley attended SUNY Oneonta while Kelly graduated from Syracuse University and Albany Law School.

“Family was the center of Suzanne’s life and she was adored for her caring, witty and wise interactions with everyone she loved,” the obit said.

“She was extremely creative, enjoyed arts and crafts and any game with family. She played a fierce gin rummy and was eagle-eyed for those trying to palm the double five in Dominos. She loved to make fun of herself and taught her children how to laugh no matter what life throws at you.”

Survivors include Crossley’s three children, her mother, three siblings and a grandson. In lieu of flowers, tributes are encouraged by making a Christmas tree ornament with a child or grandchild, or donating to the charity of their choice.

Kelly, who previously hosted shows on Fox News and NBC, launched “The Megyn Kelly Show” as a podcast in 2020 and then moved the show to SiriusXM satellite radio last year.

She did not say how many episodes she might miss after Tuesday’s funeral.

“It’s just a reminder to hug the people you love, how short and tenuous life is, and how important it is to stay close to the people you love,” Kelly said Monday.

“We can’t all be perfect on that front, but we can make a little effort day by day just to shoot a text or return a call.”
