INQUIRER: A 36-year-old man died yesterday afternoon within an hour of being beaten by four youths on a SEPTA platform a short distance from City Hall and the Center City Starbucks store where he worked. The attack happened in view of passersby and a transit policeman who was unable to help. Police said last night they had charged one of the teenagers, a 16-year-old student at Simon Gratz High School, with murder and conspiracy in the beating death of Sean Patrick Conroy, who lived in South Philadelphia and managed the Starbucks at the Philadelphia Marriott Downtown, 12th and Market Streets.
