A fired employee gunned down his ex-boss and wounded seven bystanders on the crowded sidewalks outside the Empire State Building in a Friday morning shooting spree, cops and witnesses said.

The cold-blooded killer, who was fired Thursday, wore a business suit and was carrying a briefcase when he pumped a pair of fatal bullets into his victim near the 33rd St. entrance to the skyscraper, a witness told the Daily News.

The well-dressed shooter, after casually strolling away from the murder scene, was gunned down within minutes in a Fifth Ave. confrontation with the cops.

“There was blood on the sidewalk,” said witness Rebecca Fox. “It was like a scene out of CSI, but it was real. I was literally shaking.”

Seven other people were wounded, none too seriously, before the shooting stopped just after 9 a.m.
