A 36-year-old Charlestown man has been sentenced in federal court to three years and a month in prison, followed by three years of supervised release, following his guilty plea to charges of assaulting two park rangers in August, 2004. The rangers were patrolling the Bunker Hill Monument in Charlestown just before midnight on August 18, 2004, when they interrupted the man while in the act of breaking into a car. A chase ensued. When the rangers caught him, he fought them furiously, elbowing one ranger several times and kicking the other. The rangers managed to subdue him. When he complained that he?d been injured, they summoned medical assistance. The man was placed in the back of an EMS vehicle, where he again began resisting, kicking one of the rangers backward out of the vehicle, then biting him on the hand. The incident was investigated by the NPS and prosecuted by the US Attorney?s Office.
