Texas DA, Wife Killed 2 Months After Deputy's Slaying

Kaufman, Texas (CNN) -- A Texas community is on edge after a district attorney who said he would put away the "scum" who killed a colleague two months ago was shot to death alongside his wife in his home Saturday night.

Kaufman County Judge Bruce Wood said he thought there was a "strong connection" between the slayings of Mike and Cynthia McLelland and the shooting death of Kaufman County Assistant District Attorney Mark Hasse, who was killed on his way to work in January.

Hasse and McLelland "worked on similar cases very closely," said Wood, the county's top elected official.
