A tech CEO, his wife and their two children were all found dead at their $1.5 million New Jersey mansion that burned down in a suspected arson Tuesday.

The victims were identified as Keith Caneiro, 50, wife Jennifer Caneiro, 45, and their two young children, according to NJ.com.

More than 20 fire departments responded to the blaze, which was reported on Willow Brook Road in tony Colts Neck at 12:38 p.m., officials said.

Keith was found dead in front of the house with a gunshot wound, sources told NJ.com. The wound did not appear to be self-inflicted, according to the report.

Monmouth County Prosecutor Christopher Gramiccioni would not comment on the report, or even say the dad had a gunshot wound. But he insisted, “We have no reason to believe that anyone in the community is in any danger at this time.”

The three bodies pulled from the burning home were charred, he noted.

“There was one body that was found out front of the home. The other three were recovered from the inside of the home,” Gramiccioni said.

“Unfortunately they were burned severely as a result of the fire they were exposed to. So that’s making things somewhat challenging as far as the medical examination that needs to ensue.”

Caneiro is the founder and CEO of Holmdel, NJ-based tech company Square One, according to his LinkedIn page.

His brother, Paul Caneiro, is the company’s vice president.

A fire was also reported at Paul’s Ocean Township, New Jersey, home around 5 a.m. — just hours before the Colts Neck conflagration.

No one was injured in that blaze, but gas cans were found in the rear of the home, according to local reports.

Gramiccioni said officials are investigating whether the fires are connected.

“That remains to be seen but that is an angle we continue to pursue,” he said.

A woman who answered the phone at Square One’s offices Tuesday afternoon said neither man was available and declined to comment further.

The 5,700-square-foot, five-bedroom manse was built in 2003 and was worth an estimated $1.5 million, according to Zillow.

Home prices average $750,000 in the wealthy suburb 50 miles south of New York City.

Bruce Springsteen maintains an estate in Colts Neck, and former “Daily Show” host Jon Stewart runs an animal sanctuary there.
