A pair of shootings on Tuesday afternoon and evening left two men with serious injuries and triggered a major police response on two ends of Dorchester Avenue.
In the first incident, 30-year-old Keldon Liverpool was shot in the head next to the CVS store lot at the intersection of Dorchester Avenue and Richmond St. just before 5 p.m. He was then rushed to Boston Medical Center, where he was listed in critical condition with life-threatening injuries, police said. The homicide unit was called to the scene to investigate as police canvassed the darkened parking lot looking for evidence.
