BEACHWOOD - Police say a Beachwood man witnessing an argument between his sister and her husband grabbed a gun and shot his brother-in-law to death before turning the gun on himself.

The Ocean County Prosecutor's Office says 62-year-old Richard Quattrone was arguing with his 57-year-old wife, Fatemeh, shortly after 9 p.m. yesterday.

The woman's brother, 56-year-old Kamran Ahmadimarandi shot his brother- in-law twice before calling 911 to report a shooting. He then shot himself to death.

All three people lived in the same home on Compass Avenue. Authorities say autopsies are scheduled for later today.
