A wealthy executive killed his wife and teenage daughter in their estate-like home in Westchester County, then took his own life, state police say.
Authorities identified the dead as 56-year-old Steven Dym, 50-year-old Loretta Dym, and their 18-year-old daughter Caroline.
A housecleaner discovered the bodies Friday morning in the Dyms' 4,600-square-foot home on Fox Hill Road in Pound Ridge, according to police.
The cause of death was not released.
Steven Dym was CEO of a property management company. Loretta Dym was a vice president at Club Quarters Hotels, according to The Journal News.
Dym's mother attacked her husband Lawrence Dym with a hatchet handle in the same home in 1992, The Journal News reported.
The Dyms had donated money to Gov. Andrew Cuomo. He thanked the couple for supporting him in a 2003 book.
Neighbors told NBC 4 that the house was up for sale and that no one knew the family too well.
Peter Lusk Jr., who said he's lived in the neighborhood since 1998, was on a bike ride when he saw helicopters over the area.
"That's horrible," Lusk said. "It's weird to happen around here, you don't really hear about that."
Pound Ridge is on the eastern part of Westchester County. It's bordered by Bedford to the west and Stamford, Connecticut, to the south. It's a town of less than 30 square miles with sprawling, multimillion-dollar homes for sale.
