The weapon is a “high-powered, bolt action rifle” that was “recovered in a wooded area where the shooter had fled,” Bohls said at a news conference.

Historically, bolt action rifles have had the greatest potential accuracy, especially when subjected to a refinement  called “accurizing.” Because of the low rate of fire, the bolt action rifle has not been the choice of mass shooters and has not been the subject of illicit manufacture.

An accurized bolt action rifle is the U.S. Army choice of sniper rifle designs. It remains popular in competitive target shooting.  Considerable practice is required to achieve a moderate rate of fire. This strongly implies that the shooter is likely to have had an association with a gun club or sporting team.
