Alabama investigators say District Attorney Greg Griggers was wounded in an "ambush style" shooting in downtown Demopolis Thursday. The shooter, former Alabama state trooper Steve Smith Jr., was shot and killed by police.

Authorities said Griggers was taken to the hospital for treatment and has since been released.

According to the Alabama Law Enforcement Agency, Smith was fired from his trooper job in 1996 and was not eligible to be re-hired.
