Police say it took Elisjsha Dicken just 15 seconds to subdue a man who opened fire on shoppers at an Indiana mall. The quick action they believe saved countless lives. “The amount of time between when Jonathan Sapirman came out of the bathroom and started shooting and when he was shot by the citizen was only fifteen seconds, not two minutes,” Greenwood Police Chief James Ison said in a statement Tuesday . “Surveillance video shows Sapirman exiting the restroom at 5:56:48 p.m.. He was subdued by Dicken at 5:57:03 p.m.” The statement corrects an earlier police timeline in which authorities said the incident lasted two minutes. Police also revealed that a preliminary autopsy report on the gunman showed he was hit eight times and died from his injuries, meaning Dicken only missed the shooter twice despite the threat from a distance. Police say the gunman was armed with two rifles, a Glock pistol and was carrying at least 100 rounds of ammunition. He killed three people before he was quickly neutralized by Dicken, who began to close the distance on the shooter as he motioned for bystanders to get behind him.
