Police hunt for 2 gunmen behind cookout ambush that killed 6

(AP) — Police on Friday sought to identify the two men who ambushed a backyard cookout and methodically shot and killed six people, including a pregnant woman and her fetus.

The gunmen appeared to have targeted one or two of the victims in the Wednesday night attack, and drugs haven't been ruled out as a motive, said District Attorney Stephen Zappala.

Neighbors brought balloons, stuffed animals and prayers to the home Friday at a growing makeshift memorial.

Four women, one of them eight months pregnant, and one man were killed when a gunman fired a .40-caliber pistol at the partygoers, who were playing cards and having a late-night cookout.

A medical examiner ruled the death of the fetus a homicide, bringing the fatalities in the attack to six.
