CAMDEN COUNTY, N.J. (CBS) – Crews rushed to put out an overnight house fire in South Jersey on Sunday morning. The flames broke out at 9 Second Avenue in Haddon Heights just after 4 a.m.

The homeowner says he, his wife, his son and his son’s friend were all able to escape the fire without any injuries.

Police woke up a next-door neighbor.

That man tells CBS3 he could see the flames burning his neighbor’s roof.

“It was a huge fireball that went, I want to say, 10 or 15 feet above the roof,” said James Leone.

The homeowner says he thinks the fire started near the patio.

The cause is under investigation.
