In September 2014, Bulger entered the Coleman II United States Penitentiary in Sumterville, Florida. In October 2018, he was transferred to the Federal Transfer Center in Oklahoma City, and then a few days later to the Federal Penitentiary in West Virginia. According to prison documents obtained by "The New York Times", Bulger gained a reputation for disconcerting behavior during his time in prison: "At the Coleman prison complex in Florida in September 2014, he was disciplined multiple times, including once for masturbating in front of a male staff member and once, in February, for threatening a female medical staff member". Bulger was also in poor health, as he was unable to walk and had a damaged hip, often falling out of bed. His health also declined due to a lack of exercise.
