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. And Kaufman Mayor William Fortner told CNN that he thought the men were targeted by people seeking revenge. "That's the logical conclusion, and I don't have any information that directs me to think that's the case, but that's what you would assume under the circumstances, since they targeted two people from our prosecutors." The Kaufman County sheriff's office, however, won't officially say the killings are connected. "I can't say that," Kaufman County Sheriff David Byrnes told reporters. "No, we have nothing indicating that for sure." Federal and state law enforcement descended rapidly on the crime scene to aid in the investigation. Just two months ago, McLelland vowed to find the people who killed Hasse, one of his top deputies. On Saturday, authorities found the McLellands' bodies in their home in Kaufman County, east of Dallas. "I don't know of anyone who would want to cause him harm," Fortner said. "As far as I could tell, he was doing a really good job as a district attorney." Fortner said he hoped the killer or killers were caught "before any more people are lost." Wood and McLelland last spoke last week. "He never stated to me that he was worried," Wood said. "But everybody that works in the courthouse has been on edge, but he never indicated any fear to me." Authorities are providing extra security for others, and the Kaufman County district attorney's office will be closed on Monday. "We are taking precautions to protect other elected officials in the county," Byrnes told reporters Sunday. He declined to say what those measures were. Byrnes offered no details as to how the McLellands were killed. A law enforcement source told CNN that investigators at the McLellands' home recovered several shell casings at the scene of the crime. The casings are from a .223-caliber rifle, the source said. Authorities have not identified a suspect. McLelland was an Army veteran who later earned a master's degree in psychology and became a psychologist for the Texas Department of Mental Health and Mental Retardation, the district attorney's website said. He was raised in the small town of Wortham, Texas, where his parents had a ranch. He joined the Army after attending the University of Texas and spent 23 years in the service. He later earned his law degree and practiced as a defense attorney and mental health judge for 18 years before becoming the county's district attorney in 2010. McLelland and his wife leave behind two daughters and three sons. One son is a Dallas police officer. Another top prosecutor slain . The McLellands were killed almost exactly two months after Hasse was shot to death in broad daylight outside the county courthouse on January 31. Hasse had feared for his life and carried a gun to work, said a Dallas attorney who described herself as his longtime friend. Colleen A. Dunbar said she spoke with Hasse on January 24. She said the prosecutor told her he had begun carrying a gun in and out of the county courthouse daily. "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. McLelland called Hasse "a stellar prosecutor" who knew that threats were part of the job. He vowed after Hasse's slaying to put away the "scum" who killed his deputy. "I hope that the people that did this are watching, because we're very confident that we're going to find you," McLelland told reporters. "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." Attorney Pete Schulte told CNN affiliate WFAA that public servants are facing a new quandary. "It's going to have a chilling effect on people who do want to step into those roles and (have to think about whether to) start arming themselves," he said. "I mean, that's the risk that we're going to face now because of this happening." Schulte told the station that after someone shot through the windows of his Dallas offices in November, he began to carry a gun more often. CNN's Ed Lavendera reported from Kaufman, and AnneClaire Stapleton and Holly Yan from Atlanta.

(CNN) -- Once thought to be a leading reformer inside the Libyan government, Saif al-Islam Gadhafi has emerged as one of his father's most-visible defenders. Saif, 38, has never lived a day in which his father Moammar didn't rule Libya -- as its undisputed leader inside the country and an enigmatic, controversial voice for the world. And yet, as the Libyan government faced a stiff popular uprising, it was Moammar Gadhafi's second eldest son -- and not the Leader of the Revolution himself -- who was first to talk to the nation about the unrest and detail a plan to address it. In early March Saif made it known his feeling about outside intervention into the unrest in Libya. "We're  not afraid of the America  fleet, NATO, France. You people, this  is  our country. We live here, we die here.  We will never, ever  surrender  to those terrorists. Libyan nation is so united  now. We are  so  strong," he said. That was March. This is now. And still, Saif's name makes front-page news. Citing unnamed British government sources, the Guardian newspaper reported Friday that a senior adviser to Saif -- Mohammed Ismael -- was in London for secret talks with British officials. Ismael told CNN earlier this week that he would be traveling to London for family reasons. Calls placed to his mobile phone were not answered Friday. But Guma El-Gamaty, a leader of the Libyan opposition, said Ismael's visit was anything but personal. "Our sources from Tripoli tell us that Saif has sent Mohammed Ismael to London with a specific offer. The offer is that Colonel Gadhafi will go into retirement, inside Libya, perhaps in his town of Sirte or Sabha in the south and Saif will take over and oversee some sort of reforms," he told CNN's Becky Anderson. Asked about the Guardian report, a British Foreign Office spokesman neither confirmed nor denied it. "We are not going to provide running commentary on our contacts with Libyan officials," the spokesman said. "In any contact that we do have, we make it clear that Gadhafi has to go." Meanwhile, sources close to Gadhafi have told CNN that any transition in Libya would involve his son, Saif, who has long been seen as a possible successor to his father. Saif has denied any such desire, but others were interested in the idea for some time because he was considered more modern in his thinking, even reform minded by many Libya watchers. But that was before his recent and very public vows to fight to the "last bullet." Among his relatives, Saif was seen in some ways as the polar opposite of his father. Whereas Moammar Gadhafi years ago launched a program to "destroy imported ideologies, whether they are Eastern or Western," his son speaks fluent English, earned his PhD from the London School of Economics, written an op-ed . in the New York Times and has been a frequent go-between in talks with international officials. Moammar rarely goes anywhere without a distinctive tribal dress and an ornate Bedouin tent. The well-traveled Saif, meanwhile, is more likely to appear in Western business attire: a suit and tie. While the father runs a nation, his son's main job -- at least before his 2009 appointment as General Coordinator, a position like many in the nation's government with few guidelines -- was heading a charity, the Gadhafi Foundation. And lastly, while the elder Gadhafi is known for his heavy-handed rule in Libya and its restrictions on civil rights and more, Saif Gadhafi fashioned himself as a human rights advocate and pushed for democratic and institutional reforms that could give more power and freedoms to the people. David Held, a professor at London School of Economics and Saif Gadhafi's academic advisor, said Gadhafi knew he had a dilemma. "He  was torn," said Held. "There was a dilemma in his heart between loyalty  to his father and the regime and on the other hand desperately realizng  that the Gadhafi regime was untenable, unjustified and the reform  utterly crucial." Still, his status as a leading reformer and pull with foreign diplomats have dropped significantly since the start of the uprising. And for all their differences, Saif's standing in the world is largely defined by his father's role. While some may see the son as more open to change, there's little question that his loyalty remains first with Moammar. "He's the heir apparent," CNN National Security Contributor Fran Townsend said about Saif. "The question will be, will he be able to retain control in light of the current chaos?" CNN's Greg Botelho contributed to this report.

(CNN) -- The crane operator facing charges over a deadly building collapse was denied bail Sunday. A Philadelphia judge refused to allow Sean Benschop, 42, to leave jail. He is charged with six counts of involuntary manslaughter, 13 counts of recklessly endangering another person, and one count of "risking a catastrophe," District Attorney spokeswoman Tasha Jamerson told CNN. Wednesday's building collapse in downtown Philadelphia left six dead and 13 people injured. Benschop, who maintains his innocence, turned himself in Saturday. "My client is being made the scapegoat in this situation," said Daine Grey, Benschop's attorney. "The victims here aren't just those who died and their families. My client is a victim as well. He's currently being looked at as the cause of everybody's pain, but that just isn't the case." Grey told reporters Saturday that while his client feels "extremely sympathetic and remorseful," he is not guilty. "This was an accident, but Mr. Benschop was not responsible," Grey said, in remarks captured by CNN affiliate WPVI. "And we believe that, in time, the facts will show that he is not responsible." Benschop had marijuana and pain medication in his blood after the collapse, a law enforcement source told CNN. Pennsylvania court records indicate Benschop, who also went by the alias Kary Roberts, has been arrested multiple times in the past two decades. Many of the related charges -- related to alleged firearms violations and theft -- were withdrawn, dismissed or resulted in not guilty verdicts, though he was found guilty in the mid-1990s on drug charges. Philadelphia Mayor Michael Nutter blamed Benschop's "reckless and irresponsible behavior" for the building collapse and said Saturday he hopes that Benschop faces "the harshest level of charges ... and he is punished accordingly." "Justice will only be served if Sean Benschop receives a sentence that buries him in a jailhouse forever, just like his victims were buried on Wednesday," Nutter said. Nutter is pressing for answers from two property owners who hired Benschop to operate heavy machinery, saying that, along with Benschop, they "bear the ultimate and sole responsibility for this tragedy." Benschop allegedly was working a crane to tear down a vacant building in downtown Philadelphia when a four-story wall collapsed onto a Salvation Army thrift store, causing an ominous rumble followed by panic on the streets. Afterward, searchers climbed over shards of wood, concrete and rebar looking for survivors, such as a 61-year-old woman pulled alive from the rubble early Thursday. The first lawsuit against him was filed that same day, by attorneys for a 54-year-old woman pulled from the rubble by a firefighter.
