What We Know About the Mass Shooting in Maine

From an AP story headlined “What We Know About the mass shooting in Maine”:

A man fatally shot at least 16 people at a restaurant and a bowling alley in Lewiston, Maine, on Wednesday night, sparking a massive search for a person of interest who is a trained firearms instructor. Meanwhile, authorities urged residents to lock themselves in their homes and schools announced closures on Thursday.

The shooting in the state’s second-largest city is the 36th mass killing in the United States this year, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University. The database includes every mass killing since 2006 from all weapons in which four or more people, excluding the offender, were killed within a 24-hour time frame.
