‘Let’s seek to heal,’ Obama says as Ferguson braces for another night

The Ferguson, Missouri, police officer who killed Michael Brown says the teenager rushed at him full speed in the moments before the shooting, according to an account phoned in to a radio station and confirmed by a source with detailed knowledge of the investigation.

Meanwhile, a spokesman for the St. Louis County prosecuting attorney said Monday that evidence in the shooting death could be presented to a grand jury as early as Wednesday.

According to the account on St. Louis radio station KFTK, phoned in by a woman who identified herself as “Josie,” the altercation on August 9 began after Officer Darren Wilson rolled down his window to tell Brown and a friend to stop walking in the street.

When Wilson tried to get out of his cruiser, Brown first tried to push the officer back into the car, then punched him in the face and grabbed for his gun before breaking free after the gun went off once, the caller said.

Wilson pursued Brown and his friend, ordering them to freeze, according to the account. When they turned around, Brown began taunting Wilson, saying he would not arrest them, then ran at the officer at full speed, the caller said.

Wilson then began shooting. The final shot was to Brown’s forehead, and the teenager fell two or three feet in front of Wilson, said the caller, who identified herself as the officer’s friend.

A source with detailed knowledge of the investigation later told CNN the caller’s account is “accurate,” in that it matches what Wilson has told investigators.

If true, the account represents the first telling of events from the perspective of Wilson, whose shooting of Brown has touched off violent nightly protests in the suburban St. Louis city, and prompted Gov. Jay Nixon to call out the National Guard.

A grand jury will hear testimony from witnesses and decide on whether to return an indictment in the case, Ed McGee, spokesman for the St. Louis County prosecuting attorney, said Monday, stressing there is “no time line on this case.”

In addition to that proceeding, the Justice Department has opened a civil rights investigation into Brown’s death. Attorney General Eric Holder will travel to Ferguson this week, to meet with investigators there.

“I realize there is tremendous interest in the facts of the incident that led to Michael Brown’s death, but I ask for the public’s patience as we conduct this investigation,” the attorney general said in a statement.

“The selective release of sensitive information that we have seen in this case so far is troubling to me. No matter how others pursue their own separate inquiries, the Justice Department is resolved to preserve the integrity of its investigation.”

Speaking to reporters Monday, President Barack Obama called for calm in Ferguson, saying that violence undermines, rather than advances justice.
