New Michael Brown witnesses: Cop 'just kept shooting'

FERGUSON, Mo., Sept. 11 (UPI) -- Two witnesses of the police shooting of Michael Brown came forward Wednesday saying they saw Officer Darren Wilson shoot Brown despite his hands being up.

The witnesses were contractors working 50 feet away from where Brown was killed. Both men spoke to CNN under the condition of anonymity. They said they saw Wilson approach Brown, who had his hands held in the air, when he began shooting. The witnesses said there was one shot and then another 30 seconds later.

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

They did admit that they didn't see the beginning of the confrontation, but did see Wilson chase Brown and fire a shot when his back was turned.

Protesters in Ferguson and around the country have demanded Wilson be charged with murder after shooting the unarmed teenager. The shooting has raised the issue of racial profiling and harassment by police.
