CINCINNATI (AP) — Officers' actions were justified in the fatal shooting of a man holding an air rifle inside an Ohio Wal-Mart store, a grand jury determined Wednesday — using surveillance video the slain man's family said shows the shooting was completely unjustified.

The grand jury opted not to issue any indictments in the Aug. 5 death of 22-year-old John Crawford III inside a Wal-Mart, Special Prosecutor Mark Piepmeier said.

A person who called the 911 emergency dispatch number reported Crawford was waving what appeared to be a rifle in the store. Police said he was killed after failing to obey commands to put down what turned out to be an air rifle taken from a shelf.

Since the shooting, Crawford's family had demanded public release of the surveillance footage, a request denied until Wednesday by the state attorney general, who said releasing it earlier could taint the investigation and potential jury pool.

Video presented at a news conference by Piepmeier shows Crawford walking the aisles, apparently on his cellphone, and picking up an air rifle that had been left, unboxed, on a shelf.

Crawford carries the air rifle around the store — sometimes over his shoulder, sometimes pointed at the ground — before police arrive and shoot him twice.

Exactly what happens in Crawford's final moments is difficult to make out: Crawford is at the far end of an aisle in view of one camera, the officers' feet are in view of another. Neither feed has audio and one officer's flinching foot is used as the basis for determining when shots were fired.

Crawford's family, which has called for a federal investigation, said it was "incomprehensible" that police were not indicted.

The U.S. Department of Justice said it will review the facts and circumstances surrounding the shooting. Crawford's family has sought a federal investigation to see if race was a factor. Crawford was black and the officers are white.

The Crawford family accused Piepmeier and Ohio Attorney General Mike DeWine of not attempting to get an indictment. They also said the store surveillance tape proves that Crawford's death was not justified.

Prosecutor Stacey DeGraffenreid, who assisted Piepmeier, said Crawford was shot twice by one officer, once in the elbow and once in the side under the rib area slightly from the front to the back. DeGraffenreid says no other shots were fired after Crawford fell to the floor and dropped the air rifle.

"This was a real tragedy," DeGraffenreid said in a telephone interview. But she said that based on what information the officers had when they entered the Wal-Mart, they were doing what they were trained to do.

U.S. Attorney Carter Stewart released a statement saying the department's Civil Rights Division, the FBI, and his office will conduct an independent review of the case.

The city of Beavercreek said it was asking the FBI to conduct a review. DeWine said after the grand jury's decision was announced that he thought it is an appropriate time for the Justice Department to look into whether any federal laws were violated.

DeWine said state authorities have been in frequent contact with federal officials and will turn over requested investigative files to them.

Wal-Mart customer Angela Williams, 37, also died after suffering a medical problem during the store's evacuation.
