A Suffolk Superior Court jury today found Emmanuel Pina and Sandro Tavares guilty of first-degree murder for the shooting deaths of a man with whom they'd had an argument and an innocent cook gunned down by an errant bullet at the now closed Ka-Carlos Bar and Grill in 2009, the Suffolk County District Attorney's office reports.

The verdict means mandatory sentence of life without possibility of parole. The two were also found guilty of shooting a third man, who survived.

According to prosecutors and police, Pina and Tavares opened fire outside the restaurant on Jovany Eason early on Aug. 2, 2009. One of the bullets came through a window and hit Manuel Monteiro, a cook at the restaurant who was working two jobs to put his daughters through college - and who tried to defuse an argument among the men earlier that night.

Ka-Carlos closed permanently after the murders.
