Norfolk District Attorney Michael Morrissey concluded that the police officers faced an “imminent threat” from Samuel Pattillo.

"He was naked, fighting, and he kept on coming after us," said a Dedham police officer involved in an arrest that resulted in a man's death last December.

Police officers were justified in their use of force on a man who died in police custody last year after two of his adult relatives were stabbed at a home in Dedham, Massachusetts, according to the final report from the Norfolk District Attorney's Office.
