FREEHOLD, N.J.—Suspicious of his brother over missing money from two companies they owned at the New Jersey shore, Keith Caneiro emailed two business associates last fall, saying he was going to cut off further payments to his brother, Paul.
The next day, Keith Caneiro, his wife and their two young children were found dead in their burning mansion in New Jersey horse country. Paul Caneiro was arrested on arson and other charges.
