The latest high-profile shooting in the United States happened Tuesday in Bowdoin, Maine, where four people were killed in a home and three others were wounded by gunfire on a busy highway in a neighboring community. An inmate released a few days earlier from a Maine prison was charged with the killings.
The shooting is the 17th mass killing of the year in the U.S. in which four or more people were killed other than the perpetrator, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University.
