CNN is now reporting that according to the FBI Washington field office, the Navy Yard shooter was not armed with AR-15.

That kills the narrative of several gun control activists and media outlets that highlighted the rifle as a "killing machine," because it was used by individuals carrying out shooting sprees.

"Spokesperson says 1 shotgun and 2 pistols recovered," tweeted CNN's Pamela Brown on Tuesday morning, confirming that the the shooter did not have an AR-15.

After early reports indicated Monday that the shooter did have an AR-15, Sen. Dianne Feinstein, D-Calif., quickly issued a statement.

"There are reports the killer was armed with an AR-15, a shotgun and a semiautomatic pistol when he stormed an American military installation in the nation's capital and took at least 12 innocent lives," she said. "This is one more event to add to the litany of massacres that occur when a deranged person or grievance killer is able to obtain multiple weapons-including a military-style assault rifle-and kill many people in a short amount of time."

The New York Daily News featured the AR-15 on their front page this morning with the blaring headline "Same Gun Different Slay."

CNN's Piers Morgan noted Monday on air and on Twitter that the AR-15 had been used in the shooting, linking to a Buzzfeed story the rifle.

"The AR-15 has been used seven times in past 20 months in U.S. mass shootings," he wrote on Twitter,ibing the rifle as a "killing machine."

"Almost every mass shooting involves an AR-15 assault rifle," Staff Sgt. Alonzo Lunsford told Morgan Monday night during his show, "It's the preferred mass shooter's weapon of choice."
