POLICE, PROTESTERS COLLIDE AGAIN IN FERGUSON

- The National Guard arrived in Ferguson but kept its distance from the streets where protesters clashed again with police, as clouds of tear gas and smoke hung over the St. Louis suburb where Michael Brown was fatally shot by a police officer.

Protesters filled the streets after nightfall Monday, and officers trying to enforce tighter restrictions at times used bullhorns to order them to disperse. Police deployed noisemakers and armored vehicles to push demonstrators back. Officers fired tear gas and flash grenades.

Forensic pathologist Shawn Parcells, who assisted former New York City chief medical examiner Dr. Michael Baden during the private autopsy, said a bullet grazed Brown's right arm. He said the wound indicates Brown may have had his back to the shooter, or he could have been facing the shooter with his hands above his head or in a defensive position across his chest or face.

"We don't know," Parcells said. "We still have to look at the other (elements) of this investigation before we start piecing things together."

Baden said one of the bullets entered the top of Brown's skull, suggesting his head was bent forward when he suffered that fatal injury. The hired pathologists said Brown, who also was shot four times in the right arm, could have survived the other bullet wounds.

Baden also said there was no gunpowder residue on Brown's body, indicating he was not shot at close range. However, Baden said he did not have access to Brown's clothing, and that it was possible the residue could be on the clothing.

Crump also said that Brown had abrasions on his face from where he fell to the ground, but there was "otherwise no evidence of a struggle."
