http://www.kdvr.com/news/kdvr-teenshooting-010710,0,6122302.story Police may have inadvertantly shot and injured two teen girls in Adams County Monday when officers returned fire on 4 armed robbers during a botched robbery attempt. The girls had called the police to report the home invasion only minutes before the gun fight. It happened Monday night at a home in the 7900 block of Mona Court. Two victims, girls 14- and 17-years-old, were shot and received minor injuries. Today, the girls' mother tells Fox 31 News her daughters were shot, not by the suspects, but by police. And the Adams County Sheriffs' Department confirms that is the scenario they are looking at. Police say the girls called 911 about 8 pm Monday, when four masked men burst into the house. Investigators say right now it looks like the suspects randomly targeted the house and there does not appear to be any connection between the suspects and the victims. The Department says the suspects ran outside and opened fire on arriving officers. Four officers returned fire and it looks like two of the bullets went through the walls and windows and hit the girls. None of the suspects were injured and they fled. Two have since been arrested and police are looking for the others. Law enforcement sources say this is a complicated police shooting. They say when suspects start shooting, police have a responsibility to respond to that threat. However, they also have a responsibility to make sure they are aware of their target and background and take into account any risks. It happened Monday night at a home in the 79-hundred block of Mona Court.
