A New Jersey insurance executive killed his wife and their 24-year-old daughter before taking his own life inside the family’s Montgomery Township mansion, authorities have determined.

David Grodnick, 61, his wife, Lora Grodnick, 62, and their daughter, Sloane Grodnick, were discovered dead inside the Wild Azalea Lane property on Oct. 2. All three had suffered gunshot wounds to the head, according to the Somerset County Prosecutor’s Office.

Investigators have classified the deaths of Lora and Sloane as homicides and David’s death as a suicide.

Police first went to the family’s home at approximately 2:59 p.m. on Oct. 1 after receiving a request to check on the residents.

Officers were unable to locate anyone during that initial visit, prompting authorities to begin investigating the family’s whereabouts.

Police returned the following day and entered the property shortly before 6 p.m. Inside, they discovered Lora and Sloane in separate bedrooms. David was found elsewhere in the residence with a gun still in his hand, prosecutors said.

Medical personnel pronounced all three dead at the scene. Authorities have not disclosed exactly how long they had been dead before they were found.

The property has been valued at approximately $1.75 million.

Authorities Say There Is No Threat to the Public

The Somerset County Prosecutor’s Office said its investigation indicates that the deaths were an isolated incident and that there is no continuing danger to the public.

The investigation remains ongoing, and authorities have not publicly identified a motive for the killings.

David worked as a senior vice president and underwriting counsel for Land Services USA, a Philadelphia-based insurance agency involved in commercial real estate transactions across the country.

He studied business administration at the University of Miami and earned a bachelor’s degree in English from McDaniel College, where he also played lacrosse.

Sloane had attended The Hun School in Princeton before graduating from the Savannah College of Art and Design.

At the time of her death, the 24-year-old was pursuing a master’s degree at the Rhode Island School of Design.

The family had previously lived in Princeton before moving to Montgomery Township. They were also members of Bedens Brook Country Club in Skillman and TPC Jasna Polana in Princeton.

Authorities have not announced what may have led to the tragedy, leaving the circumstances surrounding the deaths under continued investigation.
