Three people, including the gunman, were killed on Friday in a shootout in a New Jersey supermarket, the fourth such incident in the United States in over a month.
Authorities were called to the Pathmark on Route 9 in Old Bridge at about 4 am local time, NBC reported.
A heavy police presence was visible outside the supermarket in New Jersey this morning. SWAT teams had set up a command post in the parking lot of a nearby restaurant.
Friday's incident came just a week after the shooting at the Empire State Building when a "disgruntled" designer, who was sacked from an apparel company, gunned down a former co-worker and then randomly opened fire on the crowded sidewalks before he was shot dead by police.
On August 5, a gunman named Michael Wade Page had fired indiscriminately in a gurudwara in Wisconsin killing six members of the Sikh community and seriously wounding three others.

On July 20, a shooting massacre at a theatre in Aurora, Colorado -- where a gunman opened fire during a screening of the batman movie 'the Dark Knight [ Images ] Rises' -- left 12 people dead and over 50 injured.
