[EX Q]: 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.

[EX Q]: (CNN) -- You've been thinking about it for weeks. Mounds of turkey piled high with buttery mashed potatoes, dripping with gravy. Green bean casserole and pumpkin pie. Or sweet potato casserole and pecan pie. Cranberries. Collard greens. Stuffing. Every year, we spend hours making the traditional Thanksgiving favorites just like our mom used to do, like her mom did before that. "When you do something repeatedly over the years, it builds up a kind of power," nutritional psychologist Marc David says. "It creates its own momentum. To make the same dish year after year, decade after decade, there's something in that that connects us to the past." Nostalgia comes from the Greek word for homecoming (nostos) and pain (algos). But experts say feeling nostalgic is actually good for your mental health. Anything can bring on that special moment -- music, smells, photos. We play the same songs, cook the same recipes, take the same family photo in the same spot next to the same fireplace because we're human, David says. Our biological functions are based on repetitive rhythms. Our brains are hardwired to relax when surrounded by the familiar. "Emotional eating has gotten a bad name," David says. "We're emotional people. We are emotional beings. We're built for pleasure." Nostalgic products fill a need to belong and feel socially connected, according to an Arizona State University study published in the Journal of Consumer Research last year. That's why this time of year, TV and radio ads are filled with smiling families sitting around a large table in holiday sweaters, passing the dinner rolls. Even if you're far away from home, companies want you to believe that buying those same dinner rolls will fill your heart with holiday joy. Turns out, it works. Dr. Clay Routledge works with other researchers from the University of Southampton's nostalgia project. He recently published an article in the Journal of Personality and Social Psychology titled "The past makes present meaningful." Nostalgia, Routledge found, increases a person's self-esteem. Daily activities like going to class or attending meetings are routine, even boring. When we engage in nostalgia, we tend to think of the things that are really important to us. That makes us feel like our life is meaningful. Taste of Home's sweet potato tart recipe . "What's amazing about autobiographical memory is that bad memories fade faster than positive memories," Routledge says. "One thing that's interesting about nostalgia is that it's not 100% detail accurate -- it's more the highlights." Nostalgia is largely social. Routledge' s studies found that people who are alone or disconnected feel better after engaging in nostalgia. Yet you're probably dreaming right now about your grandfather's deep-fried turkey, not about him, right? "Is it really about the food?" Routledge asks. "Or is the food just sort of a trigger or cue for what the holidays are really all about, which is relationships. We don't eat these foods other times of the year because we've segmented them off as special. They go with this occasion. They go with the relationships." For Taste of Home editor Catherine Cassidy, Thanksgiving means cooking for the ones she loves. She gets satisfaction in putting good food on the table for her family. So many of our best moments from the past, she says, are rooted in our sense of smell. "We call them food memories. When it comes to the holidays we are always trying to recreate the magic and the specialness we experienced when we were children." So indulge in a little Thanksgiving daydream. Long for the oyster stuffing. Sniff the air in anticipation of mom's pumpkin pie. Then on the big day, enjoy your holiday feast, and all the benefits that come from the power of nostalgia.

[EX Q]: (CNN) -- For the first time since a reported massacre there, U.N. observers on Saturday entered the Syrian town of Tremseh, where opposition activists say more than 200 people were killed. The violence took place Thursday, on what may have been the single deadliest day in the 16-month crisis. It prompted a fresh round of condemnation from world leaders. In Tremseh, the U.N. team found evidence of an attack, including a burned school, damaged houses, and proof that artillery, mortars and small arms were used, said Sausan Ghosheh, spokeswoman for the head of the U.N. Supervising Mission in Syria. She added that the number of causalities remains unclear. "The attack ... appeared targeted at specific groups and houses, mainly of army defectors and activists. There were pools of blood and blood spatters in rooms of several homes together with bullet cases," Ghosheh said in a statement. U.N. observers are expected to return to the town Sunday to continue their fact-finding work. Still grappling with the attack, Syrians endured yet another bloody day Saturday as regime forces fired from low-flying helicopters and a bomb exploded at a state security headquarters, opposition activists said. At least 73 people were killed in Saturday violence, including 20 in Homs, 11 in Damascus Suburbs and 13 in Hama province, the Local Coordination Committees of Syria said. Fourteen additional deaths were reported in Deir Ezzor and 12 in Idlib, among others. Another opposition group, the Syrian Observatory for Human Rights, said a car bombing targeted a state security building in Hama, and "a number of state security personnel were killed and wounded." Syrian state-run TV said at least three civilians and a security officer were killed in Muhrada by a suicide bomber in a truck. Farther south, the Daraa province town of Khirbet Ghazaleh came under heavy shelling and machine gun fire after the Syrian army surrounded it with tanks, the LCC said. "Helicopters fly over the city at a low altitude with a continued siege of the city and gunfire from snipers," the opposition network said. Meanwhile, Deir Ezzor was subject to intense shelling by government forces, as well as fierce clashes between regime forces and the Free Syrian Army, the LCC said. How long can al-Assad hang on? According to the opposition network, more than 200 villagers were killed in the Hama-area town of Tremseh on Thursday, and dozens more were killed elsewhere across the country. U.N. spokeswoman Ghosheh said a large patrol had been sent from Damascus to Tremseh on Saturday to assess the situation, amid widely differing accounts of what happened from opposition activists and the government. An initial reconnaissance mission was sent Friday following assurances of a cease-fire in the area, the spokeswoman said, but it was too late in the day to do much. "The patrol assessed the situation -- if there was in fact a cease-fire and our access to the town," she said. "An 11 vehicle integrated patrol, comprised of specialized military and civilian observers, arrived ... on Saturday after confirming that a cease-fire was in place." International anger against Syrian President Bashar al-Assad has ratcheted up since the Tremseh incident, with at least one U.S. official suggesting the need for more pressure on al-Assad's regime. As outrage grows in Syria, report of a 'breakthrough' for humanitarian aid . "Through these repeated acts of violence against the Syrian people, President Assad has lost legitimacy to lead. It is time for him to go. It is time for the political transition that is long overdue to finally get under way," Josh Earnest, a White House spokesman, told reporters Friday. "It certainly does build strong international support ... to continue to ramp up the pressure on Assad," he added, citing "ongoing conversations at the United Nations about additional ways that we can build some international agreement and raise the stakes even further." Syria moving chemical weapons? Activists in the city of Hama, meanwhile, gave a grisly account of the assault in Tremseh. Witnesses inside the town told the activists by telephone that Syrian military forces had launched a full-scale attack against the opposition Free Syrian Army inside the town, which was surrounded by government tanks and artillery. As the government forces rained artillery rounds into the town, a number of village residents fled their houses, going into the streets, where many of them were shot dead by the government militias, the activists told CNN. The government painted a starkly different picture of Tremseh than that detailed by opposition groups. The state-run Syrian Arab News Agency blamed "armed terrorist groups" for the violence. It said the government said residents called security forces for help after the terrorist groups raided the neighborhood. Regime forces arrested some of the members of the terrorist groups and confiscated their weapons, the government said. Syria's detached and deluded elite? "Armed forces successfully dealt with the terrorists without casualties taking place among the citizens. They searched into the terrorists' dens where they found the dead bodies of a number of citizens who had been abducted and killed by the terrorist groups," SANA reported, citing a military source. CNN cannot independently verify reports from Syria because the nation has restricted access by international journalists. Meanwhile, many who survive the violence are caught in a precarious humanitarian situation. The chief U.N. organization that coordinates emergency aid warned Friday that more Syrians will die if contributing nations do not follow through and fund its relief operation. "We have run out of language to describe how it is for the civilian population," said John Ging, operations director and chairman of the Syria Humanitarian Forum for the U.N. Office for the Coordination of Humanitarian Affairs. "It is physical and it is psychological." CNN's Saad Abedine, Dan Lothian and Hamdi Alkhshali contributed to this report.
