At least two people were killed and one injured in a shooting inside aWalmart store in suburban Denver on Wednesday, police said.
Policein Thornton, Colorado, did not immediately release any information about the circumstances of the shooting or who was responsible for the gunfire.
In a Twitter post about 90 minutes after the shooting, police said investigators had confirmed that two men were dead and a woman was taken to a local hospital, but no further details were given.
The situation appeared potentially ominous from authorities' initial reports.
“We'vegot multiple parties down, we're still trying to ascertain what their conditions are,” Officer Victor Avila of the Thornton Police Department told Reuters by telephone not long after police arrived on the scene.
Aboutan hour after the initial alert, police said on Twitter that the threatof gunfire had ended at the store, which was surrounded by police and fire crews.
“At this time this is NOT an active shooter. Active crime scene. We will update as info becomes available,” the police department said in that tweet. Confirmation of the two fatalities came about 20 minutes later.
Avila said police were called to the store at about 6:30 p.m. Mountain time (8:30 p.m. ET) and that the gunshots had ceased by the time the first officers arrived at the scene.
