We begin tonight with arrests in connection with the latest in a series of shootings near the Mildred Hailey Apartments in Jamaica Plain. The latest incident was Monday night, with shots fired across Centre Street, one block from Jackson Square. That advice from Mayor Walsh was offered to young leaders at this morning's graduation for the "SuperTeens" program, run by the Boston Centers for Youth and Families. The event took place at the Lawn on D in South Boston. An M-BT-A ferry heading for Boston ran aground this morning, with injuries to four passengers. Officials say the ferry was cut off by a recreational fishing boat, near Long Island. Interview with Olivia Deng, Reporter, DigBoston.
