The gunfire that left two men dead in a Beachwood house Thursday night escalated out of a family quarrel, say Ocean County investigators.

Richard Quattrone, 62, and his brother-in-law Kamran Ahmadirmarandi, 56, both lived in the Compass Avenue home where the shooting occured, along with Quattrone's wife Fatimeh, 57.

Investigators, to this point, have determined that Ahmadimarandi was in the house during an argument between the husband and wife.

According to their findings, both men entered a bedroom where Ahmadimirandi pumped two rounds from a nine-millimeter handgun into Quattrone, called 911, then turned the gun on himself.

The 911 call apparently was the one to which local police responded at about 9:23 PM. They were met at the door by Quattrone's wife, and found both men lifeless in the bedroom with the gun near Ahmadimarandi's body.

Autopsies take place later today.
