UPDATE: Wife Killed Husband, Then Turned Gun on Herself in New $1.6 Million Home: Prosecutors

A man and a woman were found dead inside a newly built home in a New Jersey luxury development where mansions are on the market for over $1 million, law enforcement sources say.

Sources tell News 4 police are investigating the deaths at 4 Paddington Lane in Holmdel as a possible murder-suicide. The Monmouth County prosecutor says there's no threat to the public.

A family member told police they heard a gunshot in the house Thursday morning but for some reason police weren't called for a couple of hours, according to sources.

The home is a brand-new Toll Brothers development next to the old Bell Labs complex in the middle of Holmdel. Few of the other homes appeared to be occupied.

Two neighbors who do live in the development say a family of five lived in the home where the bodies were found: a husband and wife and their three children. They say they never saw or heard any fighting or indication anything was wrong.

Multiple law enforcement agencies were on the scene investigating Thursday; officers were seen interviewing contractors and workers in the area.

The family had moved into the $1.6 million house after closing on the home on July 21, sources say.Records show the family put down roughly $1 million as a down payment, and about $1.15 million was borrowed.
