Denise died at her Connecticut home.

Over the years, Denise and Dennis were close friends. The station’s video remembrance indicated that Denise even gave a reading at Dennis’ wedding. He married Kara Sundlun, a television journalist who has worked as a reporter at the station. Kara has an interesting background. She was the love child of the former governor of Rhode Island before suing him to pay her college tuition as a teen, then forging a strong relationship with him. She’s spoken publicly about the saga.

Dennis shared a photo of Denise at a Christmas lights event just two days before she died. No one saw the looming tragedy coming. “Come on down and join us for Holiday Light Fantasia at Goodwin Park! I’m here with @karasundlun and @DeniseDAscenzo,” he wrote with that tweet. “It benefits @Channel3kCamp @WFSBnews and @NutmegStateFCU is a sponsor!”

Just two days later, the unthinkable.

“It was a sudden and unexpected death, and the grief we are all feeling is immeasurable,” House said on air, fighting back tears. “We are devastated for her husband and daughter, who were really her whole life.”

Dennis posted this picture with Denise only five days before she died.

The station’s written announcement was similar.

“We have some heartbreaking news to share tonight,” the station wrote. “Denise D’Ascenzo passed away today. It was sudden and unexpected. The grief we are all feeling is immeasurable. We are devastated for her husband and daughter who were her whole life.”

From there, he went to WREX-TV in Rockford, Ill., where he worked as a weekend anchor. One of his exclusive interviews was with Ronald Reagan. He was later a weekend sports anchor and news reporter at WWMT-TV in Grand Rapids, Michigan.”

It adds: “Dennis was born and raised in Norwood, Massachusetts, and graduated from Xaverian Brothers High School. He holds a bachelor’s degree in foreign affairs from Assumption College.” He was born and raised in Norwood, Massachusetts.

D’Ascenzo left behind one child, a daughter named Kathryn. Her husband is named Wayne Cooke. “Denise and her husband, Wayne have a daughter, Kathryn. In her free time, Denise enjoys family outings, swimming, and hiking with her dogs,” her bio says.

On Twitter, D’Ascenzo described herself as “Anchor at WFSB, wife, mother, unofficial station nurse and dog lover.”

Denise announced that she was pregnant with Kathryn on air, saying, “I have some personal news that I’m going to share with you. I’m going to have a baby.” The station played the sound of a baby crying during the announcement.
