Two contractors who don't live in Ferguson confirm other witnesses stories that Brown had hands up...

These two contractors claim they were 50 feet away from Officer Wilson when Michael Brown was shot. They confirm the 4 other local witnesses who claim Brown was gunned down like a dog. One has his face blurred in the video. One is clearly Caucasian.

(CNN) -- Two men, shocked at what they saw, describe an unarmed teenager with his hands up in the air as he's gunned down by a police officer.

They were contractors doing construction work in Ferguson, Missouri, on the day Michael Brown was killed.

And the men, who asked not to be identified after CNN contacted them, said they were about 50 feet away from Officer Darren Wilson when he opened fire.

An exclusive cell phone video captures their reactions during the moments just after the shooting.

"He had his f**n hands up," one of the men says in the video.

The man told CNN he heard one gunshot, then another shot about 30 seconds later.

"The cop didn't say get on the ground. He just kept shooting," the man said.

That same witness described the gruesome scene, saying he saw Brown's "brains come out of his head," again stating, "his hands were up."
