Police were reportedly able to track down the Las Vegas gunman after the ferocity of his gunfire set off a smoke alarm, according to a local reporter.
At least 50 people are dead and more than 200 injured after a mass shooting at a country music festival in Las Vegas overnight. The gunman, who was shooting from the 32nd floor of a hotel, has been shot dead.
The gunman has been named by several US media outlets as Stephen Paddock, a man in his 60s, citing police sources.
Andy Vierra, programme director at KXNT News in Las Vegas, told Daisy McAndrew: "We received some unconfirmed reports that the automatic gunfire and the smoke that comes from automatic gunfire may in fact have set off a smoke detector in the room which may have helped authorities track down where the sniper was.”
He explained that it's not yet clear was the "possible motive" was and that's the reason authorities are looking for his alleged companion, who "at the very least according to the sheriff they would like to question her."
A Nevada sheriff has confirmed that one on-duty police officer is in a critical condition and another has been injured in the shooting. However Vierra suggested a number of off-duty officers may also have been caught up in the violence.
He said: "The last details that we just got in the newsroom was that there were a number of officers from Bakersfield, California that were here for the concert and at least one of them got shot...I think a couple of officers are in fact down."
However, Vierra doesn't think this will change views on guns in the area as "those folks really are very proud of their heritage and the fact they are hunters and have rifles and they carry, they pack and they're proud of it."
