A&E - The First 48 : Silent Witness / Halley Street Slayings (#13)

In Miami, when a hard-working store worker is cut down in a hail of gunfire, a veteran Sgt. Pepi Granado and his team must turn to a silent witness--the store's video surveillance system, which caught the entire murder on tape; and in Detroit, Sgt Jo AnnKinney and Detective Ed Williams tackle a case of a young couple found brutally killed in their house and learn that the victims knew their killer. They must track down reluctant witnesses deep in the narcotics game...before their killer has a chance toget away.
