LOS ANGELES (KTLA) — Dick’s Sporting Goods is making some changes to their stores in the wake of last week’s tragedy at Sandy Hook Elementary School.

The retailer is pulling certain kinds of semi-automatic rifles off its shelves nationwide.

Dick’s says it will also be removing all guns from its stores nearest to Newtown, Connecticut.

The decision came out of respect for the victims and their families “during this time of national mourning,” the store said in a statement on Tuesday.

“We continue to extend our deepest sympathies to those affected by this terrible tragedy,” the statement said.

It was unclear how long the store will keep the suspension in place for the guns, known as ‘modern sporting rifles.’

It’s also not known whether this is the first time the store has taken such a step after a shooting that made national headlines.

The move comes after reports that investigators were trying to determine whether the Newtown gunman tried to buy a gun from a Dick’s in Danbury, about 12 miles away.

“At this time, reports that the suspect visited one of our stores last week have not been confirmed by law enforcement,” the sporting goods store said in a statement.

“Based on our records, we can confirm that no firearms were sold to the suspect identified in this case.”

Meantime, Walmart, the world’s largest retailer, has pulled the Bushmaster Patrolman’s Carbine M4A3 rifle from its web store, The Nation reports.

The gun, a military-style assault rifle that uses .223 caliber ammunition, is in the same family of guns as the one reportedly used by the Newtown shooter.

Walmart did not immediately respond on Monday to requests for comment on why it pulled the gun.

Walmart, the world’s largest retailer, sells more firearms and ammunition than any national competitor, according to several news outlets.

The chain stopped selling guns in one-third of its stores in 2006, citing low demand, but it has expanded its weapons sales in recent years.

A Walmart spokesperson told the Huffington Post that it expanded guns from 1,300 to 1,750 stores in 2011.
