Watch this. This press conf was 3 hours after shooting. Pay attention to tall bald guy in suit and tie. Sheriff says suspect was down with gun shot wound when officers got there. Reporter asks well then who shot the police officer? starts at 12:40. Few minutes later tall bald suit guy gets nervous, wipes his forehead and nods at someone to his right.
Also witness said he had beard and glasses and black hat and was dark skinned. her name is Teylor Whittens (last name sp?)
