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.

Steven Dym was CEO of Gabriel Management in Queens, a managing agent of apartment buildings. His father had been president of the company for years.

Loretta Dym was vice president for global strategic memberships for Club Quarters Hotels in Manhattan. She also graduated from the FBI’s Citizens Academy in 2009 and was on the board of governors at Rockrimmon Country Club in Stamford.

Caroline Dym was entering her senior year at Sacred Heart Greenwich, where she was a member of the golf team. The couple's other child, William, just started his sophomore year at the University of Southern California.

The family's 4,661-square-foot home, at the leafy cross-section of Fox Hill, Pheasant and Bob Hill roads, features five bedrooms, 4.5 bathrooms and a lavish backyard with a pool and pergola.
