(Combined Sources) Federal authorities say Massachusetts state prisons are violating the constitution by failing to properly care for inmates with serious mental health issues and protect prisoners in crisis from harming themselves. An investigation by the Justice Department’s Civil Rights Division and the Massachusetts U.S. Attorney’s Office found troubling conditions within Massachusetts Department of Correction facilities that authorities say has resulted in prisoners dying or seriously injuring themselves while on mental health watch. A Department of Correction spokesperson said the agency has already begun to address the issues raised in the report.
