One man suffered a life-threatening injury and a second a minor wound in a shooting in Roxbury’s Highland Park section Monday night, Boston police said. A 911 call just past 9 p.m. alerted police to the attack on Beech Glen Street, said Officer Katherine Shea, a police spokeswoman. Both men were taken by ambulance to Boston Medical Center, Shea said. At the scene, police blocked off a section of the short, bow-shaped street and shined powerful lights down on the asphalt. Officers with flashlights and a police dog peered into adjacent yards. A detective on scene said shootings in that part of Roxbury are rare.Jeremy C. Fox can be reached at firstname.lastname@example.org.
