Two gunmen working as a team fatally shot five people and critically wounded two others at a backyard cookout, with one attacker using a high-velocity rifle to shoot all the victims in the head as they were driven his direction, a prosecutor said Thursday.

"The murders were planned. They were calculated," District Attorney Stephen Zappala said.

The gunmen appeared to have targeted one or two of the victims, said Zappala, who said they hadn't ruled out drugs as a motive.
