A wave of violence in the District of Columbia and Prince George’s County left four men dead and two men critically injured within a 12-hour period stretching from late Wednesday night through Thursday morning.

The two Thursday morning homicides in the District, not far from Union Station on the unit block of K Street, NW, were the 117th and 118th of this year, pushing the year’s total to a nine percent increase over the same period in 2007.
