3 slain in 12 hours

Three people were murdered in separate incidents during a 12-hour spate of violence in Queens over the weekend, police said.

The bloodshed first erupted at around 5:45 p.m. Saturday, when career criminal George Portillo, 31, got in a fight with an unknown gunman on 95th Street and 31st Avenue in East Corona. Portillo was shot in the chest and died at Elmhurst Hospital.

Police said his rap sheet included arrests for rape, assault, DWI and drugs.

Another slaying occurred at 1:16 a.m. yesterday in South Jamaica, when 20-year-old Cody Kahn was fatally shot in the chest. Cops did not know what sparked the killing.

Fewer than five hours later, police found two men shot in Hollis — a 28-year-old man slumped over the steering wheel of a Nissan Altima at 209th Place and 111th Road and a 31-year-old man on the sidewalk nearby. Both men were rushed to Jamaica Hospital, where the 28-year-old succumbed to his injuries.
