Body Splattered on Congress Street in Soulless Southie

I really didn't want to be in a cab this morning, and when the Terminal A ATM turned out to be out of cash, I just took the Silver Line. In the glass and glitter part of Southie were many flashing lights, belonging to Boston, Massport, and State Police vehicles. In front of the building that Silver Line buses pass through, a lump under a white sheet with a spurt of escaped blood slowly drying on the dewdamp asphalt. What happened?
