KAUFMAN, Texas — Kaufman County District Attorney Mike McLelland took no chances after one of his assistant prosecutors was assassinated two months ago. McLelland said he carried a gun everywhere he went and took extra care when answering the door at his home.

“I’m ahead of everybody else because, basically, I’m a soldier,” the 23-year Army veteran boasted in an interview less than two weeks ago.

On Saturday, he and his wife were found dead in their home just outside the town of Forney, about 20 miles from Dallas, killed in an attack for which authorities have given no motive.

“Everybody’s a little on edge and a little shocked,” Forney Mayor Darren Rozell said. “It appears this was not a random act.”

The killings came less than two weeks after Colorado’s prison chief was gunned down at his front door by a white-supremacist ex-convict, and two months after Kaufman County Assistant District Attorney Mark Hasse was shot to death in a parking lot a block from his office Jan. 31. No arrests have been made in Hasse’s slaying.

Kaufman County Sheriff David Byrnes confirmed Sunday that the McLellands had been shot. As for whether their deaths were related to Hasse’s slaying, Byrnes said there was nothing to indicate that “for sure,” but declined to discuss it further.

McLelland himself, in an Associated Press interview, raised the possibility that Hasse was gunned down by a white supremacist gang. McLelland, elected DA in 2010, said that Hasse hadn’t prosecuted any cases against white supremacists but that his office had handled several, and those gangs had a strong presence in the area.

“We put some real dents in the Aryan Brotherhood around here in the past year,” McLelland said after Colorado’s corrections director, Tom Clements, was shot to death March 19 when he answered the doorbell.

Kaufman Police Chief Chris Aulbaugh said recently the FBI was checking to see if Hasse’s killing could be related to Clements’. Evan Spencer Ebel, a former Colorado inmate and white supremacist who authorities believe killed Clements, died in a March 21 shootout with Texas deputies about 100 miles from Kaufman.
