KAUFMAN, Texas (AP) — The top administrator in the county where a Texas district attorney and his wife were killed says he is "certain" he and other officials are being protected.

Kaufman County Judge Bruce Wood declined Monday to discuss details but acknowledged extra security is in place at the county courthouse where District Attorney Mike McLelland worked. McLelland and his wife, Cynthia, were found shot to death in their home Saturday.

Assistant prosecutor Mark Hasse was gunned down just two months ago outside the courthouse. Officers were seen patrolling one side of the building Monday morning, while others walked around inside.

McLelland's office is closed Monday. The judge says officials will meet with members of McLelland's staff later in the day to help get a feel for what their needs are.
