NEW YORK — New York City police are investigating the gruesome discovery of a woman after she found her friends dead with their throats slit in their Brooklyn home.

On Sunday afternoon, the woman went to visit Jacqueline Delyons, 66, and her father, Roosevelt Simmons, 91, at their place in Cypress Hills.

She found them lying on the kitchen floor with slash wounds and immediately called 911, police said.

The victim’s boyfriend was arrested

According to police sources, Delyons’ boyfriend was in the home when the woman arrived. She asked him what happened after seeing the bodies and he allegedly replied: “You know what happened.”

Police detained Lewis Kerry, 46, for questioning before arresting him on Monday.

“Shocking to me. He doesn’t seem like the kind of person who would do something like that,” said Hubert Walcott, a neighbor.

“I never heard the guy curse, nothing like that. The guy was a good guy, but I don’t know what happened,” said Darryl Moorer, a family friend.

Kerry was charged with first-degree murder and third-degree criminal possession of a weapon, police said.

The community mourns the death of father and daughter

Meanwhile, family and friends were mourning the deaths of Delyons and Simmons, whom they called “Bubba.”

“Right now, we’re still trying to figure it all out,” said Ramon Berghout, Delyons’ former partner. “Jackie was the mother of my son… Beautiful person.”

“She’s a very friendly person, Jackie,” said Walcott.

“I’ve been on the block for over 45 years. Bubba and Jackie are good people,” Moorer said. “Bubba used to come to our barber shop all the time, get regular haircuts.”

Delyons and Simmons have lived in the neighborhood for decades, neighbors said, adding that they never had concerns about suspicious activity at the home.
