Texas sheriff: Extra security after DA killed

Kaufman County Sheriff David Byrnes confirmed that District Attorney Mike McLelland and his wife had been shot. As for whether their deaths were related to the slaying of an assistant DA, Byrnes said there was nothing to indicate that "for sure." The couple's bodies were discovered inside their home just outside the Texas town of Forney, about 20 miles from Dallas. (March 31, 2013)
