Officials: Husband, wife, kids killed before NJ mansion fire; brother in custody

COLTS NECK, N.J. (AP) -- Prosecutors say the four people found dead at the scene of a New Jersey mansion fire have been identified as a husband and wife and their two children, and each were victims of "homicidal violence" before the blaze was intentionally set.

Monmouth County Prosecutor Christopher Gramiccioni says Keith Caneiro was found shot outside the Colts Neck mansion. The others were found inside the burning home Tuesday.

He says he can't say if the other three were also shot. They were severely burned, making examination difficult.

The developments came hours after Caneiro's brother, Paul Caneiro, was charged with aggravated arson. He's accused of setting fire to his own Ocean Township home, about seven hours before the mansion fire was reported. No attorney information is available.

Gramiccioni says the Caneiros worked together at a technology business.
