MORRIS TOWNSHIP, N.J. (PIX11) – A New Jersey couple — both in their 80s — were likely killed when their home was destroyed by a fire in the middle of the night.

The fire happened at a home in Morris Township on Normandy Heights Road just before 3 a.m. Friday, according to the Morris County Prosecutor’s Office.

The fire was first reported to authorities by pilots who spotted massive flames while flying overhead, officials said.

The home was engulfed in flames when fire crews arrived, hindering firefighters in their search for the residents.

Robert Ricciardi, 87, and Gemma Ricciardi, 85, were likely killed in the fire, but their bodies haven’t been found as investigators searched through the rubble, officials said.

The Ricciardis were well known in the area, neighbors told PIX11 News. Robert Ricciardi founded the paint business Ricciardi Brothers, which has more than 40 stores across multiple states.

The Ricciardis’ nearly 10,000-square-foot home was built 128 years ago in 1894, according to city officials.

The cause of the fire was under investigation.
