A Pawtucket man will spend the next 14 years behind bars for impersonating a police officer while breaking into a Providence home.  Jeffry Rosario was sentenced yesterday for the August 2016 robbery.  Court documents show Rosario, wearing a badge and bulletproof vest, knocked on the door of an Alverson Avenue home and told the residents he was an officer conducting a welfare check.  A man and a woman were tied up, but the woman escaped as Rosario and three other men robbed the home.
