 D.C. police score high marks from criminologists at New York University. I'm Dick Uliano. A body pulled from one popular swimming destination for the third time in the last two months. I'm Grace Newton. Two men are dead after a shooting at an area gym. A day at work turns deadly at a Virginia car wash. I'm Liz Anderson. It is 3 o'clock. This is CBS News on the Hour, sponsored by O'Reilly Auto Parts.
