A couple and their adult son were found fatally shot in their burning home, but police weren't looking for any suspects, authorities said Thursday.

Acting Bergen County Prosecutor Gurbir Grewal said the fire was intentionally set, and there are no suspects to pursue.

"The matter is limited to a domestic event," Grewal said.

Police received a 911 call about the house fire in Fair Lawn late Wednesday, Grewal said.

Authorities arrived and found a firearm and the bodies of 76-year-old Richard Tempe, his 73-year-old wife, Barbara, and their 53-year-old son, Richard Jr., inside the home.

Authorities were awaiting autopsy results.

Pam Coles, who grew up next door to the Tempes, told The Record newspaper that they were good people. She said they had an almost open-door policy. If her family ever needed anything, they would knock on the Tempes' door, and the Tempes would help, Coles said.

"They were a wonderful family," she said. "I'm so surprised."

Valerie Cook, who lived across the street from the Tempes for decades, said they were the first to welcome them to the area after a 1978 blizzard. They had just moved to the neighborhood a month before.

She told the newspaper the Tempes were friendly and active in the neighborhood.

"I have to tell you I am very, very upset," she said. "There was no indication that something was amiss."
