The gunman stood in the parking lot and shot several times, witnesses and police told the Boston Globe, which added that one man inside the cluster of buildings sustained nonlife-threatening injuries and was taken for treatment at Mount Auburn Hospital.

The shooter was identified as a 70-year-old man from Framingham, Middlesex District Attorney Marian Ryan's office reported in a statement. 

“It was a former employee who did shoot at a co-worker,’’ Cambridge Police spokesman Jeremy Warnick said to the Globe.

The shooter had allegedly been waiting for the victim, a 58-year-old Cambridge man, to arrive, CBS Boston reported, adding that the suspect committed suicide in the incident.
