St. Louis County police, who have been asked to take over the investigation by the Berkeley police department, released a surveillance tape from the scene that they say shows Martin pointing a gun at the officer before the officer fired his weapon:

Immediately after the shooting, protesters gathered at the scene and clashed with police:

And here is the latest from the St. Louis Post Dispatch:

A Berkeley police officer fired at least three shots at a suspect who pulled a gun on him, the St. Louis County Police chief said at a Wednesday morning news conference.

Police Chief Jon Belmar said the officer was doing a business check at a Mobil on the run station about 11:15 p.m. Tuesday when the shooting happened.

The officer saw two people on the parking lot in the 6800 block of North Hanley Road and began talking with them.

Belmar said one of the people approached the driver’s side of the vehicle.

One of the individuals “produced a pistol with his arm straight out, pointing it straight at the officer kind of from across the hood,” Belmar said.

At that point, the chief said, the officer got his service revolver “and fired what we think is three shots.”

The officer, who is 34 and white, is a 6-year veteran of the department, Belmar said.
