 Middlesex District Attorney Marian T. Ryan, whose office is helping to investigate the incident, said at a press conference Watertown police responded to a 911 call for a road-rage incident.  A Massachusetts man is in custody after the woman he was with was struck and killed Wednesday by a tow truck, prompting him to stab the driver of the vehicle, police say. The district attorney’s office declined to confirm either identity Wednesday night. The driver of the truck involved was also taken to Boston-area hospital where he remains in critical condition. Investigators say the man whom she was with “engaged in an altercation with the tow truck driver stabbing him multiple times in the abdomen.” He remained on the scene and was taken into police custody.
– A vehicle vs. pedestrian accident in Watertown, Mass., left a woman dead on Wednesday. The violent aftermath of the crash left the driver of the flatbed tow truck that hit her in critical condition and another man in police custody.
