(NECN: Boston, Mass.) - A couple from Brentwood, New Hampshire, is suing a psychiatric hospital in the wake of the deaths of their children. Ken and Danielle Lambert are reportedly suing McLean Hospital in Belmont, Massachusetts, for allegedly providing inadequate care for Danielle's mentally ill identical twin. In 2008, her twin carried the couple's two young children into traffic on I-495. All three of them died. This was just a few months after the twin had been released from McLean. Boston Globe Deputy City Editor Mike Bello joins NECN for a discussion.
