One week after the bodies of a family of four were discovered after their New Jersey mansion became engulfed in flames, the slain father’s brother has been charged in their killings, PEOPLE confirms.
Paul Caneiro, 51, is accused killing his business partner brother, his wife and their two children before their Colts Neck mansion was set on fire on Nov. 20.
The charges — four counts of murder — were filed early Thursday, court records obtained by PEOPLE show.
Caneiro has not yet entered pleas to the charges, and information concerning his defense lawyer was unavailable.
He has been in police custody since last week, when he was detained on a single count of aggravated arson after he allegedly set fire to his own residence in Ocean Township with his wife and kids inside.
