Kaufman County is on edge. Two prosecutors killed in two months, including the district attorney, gunned down in his home over the weekend.
What's going on? Is someone assassinating prosecutors?
As armed guards surround the Kaufman County Courthouse and police shrouded some public officials in around-the-clock protection, it seems there are as many questions as answers.
District Attorney Mike McLelland and his wife, Cynthia, were shot to death, nearly two months after one of his assistants died in a brazen daytime shooting outside the north Texas county's courthouse.
A search warrant affidavit stated the couple was found dead Saturday evening by friends who had tried to reach them several times during the day. Each of them had been shot multiple times, the affidavit states.
McLelland talked to relatives on Friday night, the affidavit states. Investigators have asked a judge for records of mobile phone calls that were relayed through at least one nearby tower, the documents show.
The killings followed warnings that a white supremacist group might be preparing to take revenge on law enforcement officials who targeted them in 2012.
It's unclear whether the McLelland killings were linked to the January 31 shooting death of Kaufman County assistant prosecutor Mark Hasse, or to the March 19 death of the prisons chief in Colorado. Authorities say a suspect in that shooting was a onetime white supremacist gang member who died in a shootout with deputies -- in north Texas.
"This whole thing is shocking to all of us," said Kaufman County Judge Bruce Wood during a Monday news conference. "I would be less than honest if I told you I was not worried."
Michael Burns, McLelland's law school classmate, longtime friend and fellow district attorney, said that after Hasse's killing, McLelland told him, "They better come prepared because there'll be a fight."
Both Kaufman County prosecutors apparently started carrying guns, but it wasn't enough.
Brandi Fernandez, McLelland's first assistant district attorney, will take over the office on an interim basis until Gov. Rick Perry can appoint a successor, county officials announced.
The McLellands' bodies were found Saturday at their home in the Dallas suburb of Forney.
A law enforcement source told CNN that investigators have recovered several shell casings from a .223-caliber rifle.
Mike Griffith, whose yard backs up to the McLellands', told CNN affiliate WFAA-TV he thinks he heard the attack unfolding early Saturday.
"It was five or six shots, one right after the other," WFAA quoted Griffith as saying.
The deaths came almost exactly two months after Hasse was shot dead and the day McLelland vowed to bring his killer -- he used the word "scum" -- to justice.
"We're going to pull you out of whatever hole you're in, we're going to bring you back and let the people of Kaufman County prosecute you to the fullest extent of the law," he said.
Hasse had feared for his life and carried a gun to work, said a Dallas attorney who described herself as his longtime friend.
Colleen Dunbar said she spoke with Hasse a week before he died and he told her he had begun carrying a gun at work.
"He told me he would use a different exit every day because he was fearful for his life," Dunbar told CNN.
She said that Hasse gave no specifics on why he felt threatened, only that he did.
A neighbor said Cynthia McLelland had been concerned that Hasse wouldn't be the only person killed, but she thought her husband would be OK.
"And I said, 'What about Mike? You think he's safe?' And she said, 'Yeah, I'm not worried about about Mike,' " David Crone told WFAA.
