• In 1998,
Michael Chasse was arrested for breaking into the home of Robert Cohen, the brother of former Maine Senator
William Cohen. As Chasse was being escorted to his trial for the break-in, he threw a white powdery substance into the guards’ faces and ran off, but was caught five hours later. • On November 11, 2005,
Portland Phoenix newspaper began an exposé series detailing the prison's alleged misuse of forcible extraction techniques and
restraint chairs. Following a wave of public criticism, Corrections Commissioner Warren Magnusson promised to "de-escalate" use of the restraint chair, and asked the US Department of Justice's National Institute of Corrections to review the management of Maine Supermax. • On June 30, 2008, Chasse, by then a prisoner of the Maine State Prison, took another prisoner and a staff member hostage. Chasse had what appeared to be a knife taped to his hand. After a seven-hour stand off, the two hostages were released with minor cuts. On November 3, 2011 Michael Chasse died while at the New Jersey State Prison, where he had been sent since Maine could no longer hold him in the prison due to his behavior. •
Gary Watland, a prisoner at the Maine State Prison serving a 25-year sentence for murder, devised a plan to have his wife, Susan Watland, bring a gun into the prison with the intent of taking hostages. Another prisoner alerted staff. On October 24, 2006 Susan Watland entered the prison with a loaded pistol but was apprehended by officials before any shots were fired. She was arrested and later sentenced to three years in prison with credit for time served, probation, and a fine. She has since been released. Gary Watland has since been transferred to the
ADX Florence, a supermax penitentiary in
Florence, Colorado. ==Special Management Unit==
