The victims of about half of Maine’s two-dozen or so murders each year are related to their assailants, who are their husbands, wives, parents, brothers and so on. Other murders are linked to drugs or alchohol, in some manner — deals gone bad, substance abuse leading to conflict, etc. Can efforts be made to reduce the domestic violence murders? What about drug- and alcohol-related murders? Will both domestic violence and substance-related killings become more common? So far, random violence seems to be rare in Maine. Will this remain the case, or are forces such as drugs bringing that sort of violence here?
