NY State Police said that a real estate executive used a shotgun to fatally shoot his wife and daughter in their Pound Ridge home before turning the gun on himself.

A housecleaner found the bodies of Steven Dym, 56; Loretta Dym, 50; and Caroline Dym, 18, "on the second-floor landing" of the home at 23 Fox Hill Road on Friday morning and called the police. Officers from both the state police and Pound Ridge police department responded by 11:10 a.m., and the state police determined that it appeared Steven Dym had committed a murder-suicide.

Lorretta Dym and Caroline Dym each died of single shotgun wound to the stomach while Steven Dym shot himself in the head.

Steven Dym was the CEO of Gabriel Management, a Queens-based real estate management company his father started, while Loretta Dym was a vice president at Club Quarters, which helps business travelers find full-service accommodations. Caroline Dym was a rising senior at a Connecticut private school, Sacred Heart Greenwich, where she was a member of the golf team. She had placed second, with a partner, in the CT Stem Fair.

Sacred Heart head of school Pamela Juan Hayes said on Saturday, "This morning, I met with members of our senior class to support them as they cope with the trauma of losing their cherished classmate and deal with their personal sorrow."

The Daily News spotted a friend of Caroline's placing flowers outside the house, with a note that read, "I miss you so much and I wish I had the chance to say goodbye. You truly were the happiest, kindest, funniest, and most caring girl I knew. Your smile was the most beautiful and I will always remember it. I am at a loss for words, Caro, but all I can say is that I love you forever and I’ll never forget you."

The friend told a News reporter, "She had a bubbly personality. She was really kind."

Police are continuing to investigate the incident for a possible cause. According to the Post, "The couple was not going through a divorce, and police said they have not received previous calls for domestic incidents involving the family. But the family’s home was up for sale, and those who recently spoke to Steven said something seemed off... Steven may have been struggling financially, according to a police source."

The home, which had 5 bedrooms, 4 1/2 baths and a pool on 2 acres, was on the market for $1.699 million and features elegant finishes. Online real estate sites said the house was no longer for sale, possibly due to an offer.

A realtor who met Steven Dym told the Post that "Dym acted 'very weird' when asked where the family was moving. 'Not only did he not know where he was going, but he didn’t even know if he was going.'"

However, the home was not always so sumptuous. A neighbor who lives next door spoke to the News, saying that Steven Dym actually grew up in the house: "Back then, the house was much smaller, like mine. Then he blew it up and he built this... The last 10 years their kids went off to private school, and my kids stayed in public school, so there was a disconnect after that."

The home is also where Steven Dym's mother, Paula, apparently attacked his father, Lawrence Dym, with a hatchet in 1992. Paula Dym was hospitalized for psychiatric evaluation while Lawrence Dym survived the incident.

Steven and Lorreta Dym's son, William, 20, is a sophomore at University of Southern California and was at school at the time of the attacks. He reportedly flew home after learning about the deaths.

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.
