The Wichita Police Department says an incident that injured three police officers over the weekend was not a planned attack.
Police were entering a vacant house in the 1400 block of South St. Francis on Saturday when a modified shotgun went off, injuring three officers. They were responding to reports of a break-in. At the time, it was unclear whether the shotgun had been booby trapped.
Police Chief Gordon Ramsay said Monday that it appears the gun went off accidentally. He said the loaded, sawed-off shotgun was wedged in the side pouch of a recliner with a knife, bat and other items when an officer likely bumped the chair, causing the gun to fire.
"The shotgun that was in that pouch was modified and had no trigger guard ... making it very dangerous and easy for that trigger to be pulled," Ramsay said. "And at this point in the investigation we do not believe that this was a trap, ambush or type of attack aimed at police ofifcers or any intruders, for that matter."
He said an investigation is ongoing. A man and a woman who had been illegally squatting at the residence were arrested Sunday and face several charges each, including burglary, theft, discharge of a firearm, and criminal possession of a firearm.
A spokesman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, which is assisting the WPD with the investigation, says the couple may face additional federal firearms charges.
Local and federal authorities continue to investigate a shooting that injured three Wichita police officers.
