A couple who worked in NYC and their 18-year-old daughter were found dead in their Pound Ridge home on Friday morning. The NY State Police said that, based on a preliminary investigation, "Steven Dym, 56, took the life of his 50-year-old wife Loretta Dym, their daughter, Caroline Dym, age 18, before taking his own life."

Police responded at the home on 23 Fox Hill Road after a housecleaner found the bodies. The causes of death were not disclosed and the Westchester County medical examiner's office will conduct the autopsies.

Pound Ridge is an affluent Westchester County suburb about 50 miles from Manhattan, bordering Connecticut to the east. The town's police chief David Ryan "said it’s the only murder in the 19 years he’s been with the department," according to WCBS 2.

Steven Dym led a real estate management firm, Gabriel Management, based in Queens, while Loretta Dym was an executive with Club Quarters, which finds full service accommodations for business travelers. Their daughter Caroline was a student at Sacred Heart Greenwich, where she was a "standout" on the golf team. A son, William Dym, 20, is a sophomore at University of Southern California; he was reportedly traveling back to New York after learning about the deaths.

The Post noted that the couple "were donors during Andrew Cuomo’s failed gubernatorial run in 2002 — and he thanked the couple for their support in his 2003 book 'Crossroads: The Future of American Politics,'" earning mentions as "'extended family' listed in the book. The pair donated a combined $4,150 to that campaign, records show. They did not contribute to any of his later endeavors."

Cuomo spokesman Rich Azzopardi said, "The acknowledgements in the book were to thank many past supporters from the 2002 campaign. The governor has not seen or heard of this person in 15 years."

Neighbors told WABC 7 that "the Dyms had been in the midst of marital problems."

Peter Lusk Jr. told WCBS 2, "It's like the quietest place in the world. It's tragic. It's sad."

Another neighbor, Kerry Labritz, said to the news channel that the Dyms were a "[q]uiet, nice family. Everybody pretty much in this area is quiet, keeps to themselves," and added, "They had a for sale sign up and one of my friends was a realtor, so people were going over and looking at the house and stuff, and I think they were actually selling the house."

The 4,661 square foot home on Fox Hill Road was on the market for $1.699 million, with 5 bedrooms, 4 1/2 bathrooms and a pool on two acres. One real estate website said its status is "contingent" or "The seller has accepted an offer but it's contingent on something else happening, like the buyer selling their home."

The Journal News reports, "It was not the first violent episode at the house. On Nov. 11, 1992, Steven Dym’s mother, Paula, attacked her husband Lawrence with the handle of a hatchet, striking him in the head as he slept. Lawrence Dym survived and his wife, who was under stress at the time for a medical condition, was hospitalized for psychiatric evaluation."

Police Chief Ryan remarked on the tragedy, "You have a young family, and two young children, and there’s a surviving child. Imagine the heartbreak for that young boy."

If someone you know exhibits warning signs of suicide: do not leave the person alone; remove any firearms, alcohol, drugs or sharp objects that could be used in a suicide attempt; and call the U.S. National Suicide Prevention Lifeline at 800-273-TALK (8255) or take the person to an emergency room or seek help from a medical or mental health professional.
