[Q]: The gunman who held hostages for more than 16 hours in a Sydney cafe was no stranger to police -- and was on bail for violent criminal offenses at the time of the siege. Man Haron Monis, an Iranian-born refugee who was granted political asylum in Australia in 2001, had "a long history of violent crime, infatuation with extremism and mental instability," Australian Prime Minister Tony Abbott told reporters. "It's pretty obvious that the perpetrator was a deeply disturbed individual," he said at a press conference Tuesday, adding that the 50-year-old was "well known" to federal and state police, as well as the Australian Security Intelligence Organization. "But I don't believe he was on a terror watch list at this time." New South Wales Premier Mike Baird said authorities were investigating why Monis -- who was killed in the siege -- was at large, given his criminal background. "We're all outraged that this guy was on the street," he told reporters. "We need to understand why he was. We also need to understand why he wasn't picked up." What we know, what we don't know . Accessory to murder, sex charges . The self-styled Muslim cleric, also known as Sheikh Haron, was facing dozens of charges at the time of the siege, including two counts of being an accessory to the murder of his ex-wife, according to the Attorney General of New South Wales. Noleen Hayson Pal was found dead with multiple stab wounds in a stairwell, and her body had been set on fire, The Sydney Morning Herald reported. "They should have put him away and thrown away the key," the dead woman's godfather, Ayyut Khalik, told NBC News. He said Monis used to beat Pal, forcing her to wear a hijab all the time and forbidding her from talking to "outsiders." Court documents show Monis was also facing 45 sex-related charges, including sexual intercourse without consent and aggravated indecent assault. According to the Sydney Morning Herald, the initial charges, laid in May 2014, related to an alleged sexual assault on a woman in western Sydney in 2002, before other sex-related charges were added regarding six additional victims. Monis was using the name Mohammad Hassan Manteghi -- his birth name, according to Iran's state news agency IRNA -- and claimed to be a "healer," according to the report. Monis also pleaded guilty last year to writing offensive "poison pen" letters to the families of Australian soldiers who died in Afghanistan, and was sentenced to 300 hours of community service. The letters were "sadistic, wantonly cruel and deeply wounding," one High Court judge said at the time, according to CNN affiliate Seven News. But the criminal accusations against him began even before he came to Australia. Monis fled his homeland in 1995 while being sought for allegedly committing fraud, Iran's semi-official Fars News reported. A spokesperson at Iran's embassy in Canberra told CNN that Tehran had officially requested Monis's extradition but nothing had come of it. Monis had been granted political asylum in 2001 and had had no further contact with his birth country, the spokesperson said. Who were the victims? An extremist theology . Manny Conditsis, a lawyer who acted for Monis in relation to the accessory to murder and letter-writing charges, told CNN his former client had been a cleric in Shiite Iran, but had become critical of the Islamic Republic's government in the late 1990s, and fled to Australia "because he was going to be killed." He had left behind a wife and two children, who he believed Monis had not seen since. Throughout the 2000s, said Conditsis, Monis "became sympathetic to what he perceived ... was the victimization of Muslims and Islamists around the world, and partly at least took up that cause." His broader cause, he said, was lobbying governments around the world, particularly Australia, not to wage wars on Muslim soil. "He was so blinded by that objective that it would seem he had lost sight of objectivity and rationality and acted in extreme ways," he said, describing his former client as "intensely conflicted and contradicted and inconsistent." While older footage of Monis preaching shows him dressed in typical Shiite cleric's attire, in his social media posts, he appears to embrace a radical Sunni extremist theology. He used the Internet to spread extremist beliefs, garnering nearly 13,000 likes on his Facebook page. During the siege, Abbott said, the hostage-taker "sought to cloak his actions with the symbolism of the (ISIS) death cult," Abbott said. On his website, which has now been taken down, there was a pledge of allegiance to the so-called Islamic State terror group. The site describes Monis as a Muslim cleric and activist based in Sydney who has "continuously been under attack & false accusation by the Australian government & media since he started his political letter campaign from 2007." There's a graphic photo of slain children at the top of the site. Under the image, it reads, "This is an evidence for the terrorism of America and its allies including Australia. The result of their airstrikes." A description on the site portrayed Monis as a victim of a political vendetta and compares him to Julian Assange, the WikiLeaks founder who has claimed the sex crime allegations he faces are politically motivated. A YouTube video posted in November shows Monis standing on a street corner, chains draped over him, carrying a sign that says, "I have been tortured in prison for my political letters." Police have refused to comment on that accusation. His last tweet linked to his website, with a haunting message posted the day of his attack on the Sydney cafe: "If we stay silent towards the criminals we cannot have a peaceful society. The more you fight with crime, the more peaceful you are." Conditsis  told Australian public broadcaster ABC that Monis was an isolated figure who was probably acting alone. Crisis in a cafe . Monday's hostage situation began around 10 a.m. Hundreds of police officers, including snipers, took position around the Lindt Chocolate Cafe in Sydney's central business district. Australian media captured haunting images of hostages pressing their hands against the cafe's windows. They were reportedly taking turns holding a black flag with Arabic writing on it that said, "There is no God but God and Mohammed is the prophet of God." The man holding the hostages demanded to speak to Abbott. Police were monitoring social media because hostages appeared to be posting information about the man's demands. Hours into the crisis, at least five hostages managed to escape, running terrified toward police in riot gear. That made the hostage-taker furious, reported Chris Reason, a correspondent for CNN affiliate Seven Network. Reason said he could see the gunman become "extremely agitated" when he realized what had happened, and he "started screaming orders" at the remaining hostages. Gunfire erupted early Tuesday as police stormed the cafe where the gunman had been holding hostages. Two hostages were killed during the standoff. Police later announced that the siege was over and that the lone gunman had been killed.

[Q]: (CNN) -- In brief remarks to the media just after returning to her hometown of Seattle, an emotional Amanda Knox thanked those who believed in her and supported her fight to overturn her murder conviction in Italy. "I'm really overwhelmed right now," said a tearful Knox, who arrived to cheering supporters at Seattle-Tacoma International Airport. "I was looking down from the airplane, and it seemed like everything wasn't real." "What's important for me to say is just thank you, to everyone who has believed in me, who has defended me, who has supported my family," she said, her voice shaking. Being with her family, she said, is "the most important thing to me right now." "Thank you for being there for me," she said. Knox and her family were on a British Airways flight that landed in Seattle about 8:12 p.m. ET. Before beginning her remarks, Knox smiled and said, "They're reminding me to speak in English, because I'm having problems with that." An Italian appeals court on Monday overturned Knox's murder conviction in the 2007 death of her roommate, British student Meredith Kercher. Knox initially was sentenced to 26 years in prison. Knox's mother and stepfather, Edda and Curt Mellas, also thanked those who have supported their family, as well as the Italian attorneys who fought on her behalf. "Meredith was Amanda's friend," said Philadelphia attorney Theodore Simon, who spoke at the news conference. Knox wants the Kercher family to be remembered, Simon said as Knox nodded and appeared to fight tears. Knox supporters in Seattle said they planned a rousing welcome. "To Amanda herself, we say, 'Way to go, kid,' " Tom Wright, founder of the group Friends of Amanda Knox, said Monday night. "We look forward to welcoming you home with open arms and open hearts," Wright said, reading a statement. "You have well deserved, and will well deserve, all the joy and warmth and fun of your normal life returned to you." The statement also said that it was "primarily a sad occasion," and that the group's "deepest sympathies" were with Kercher's family. CNN affiliate KOMO-TV reported that Wright was among a group of more than a dozen supporters who gathered at a hotel suite to watch the jury return its decision about Knox more than 5,000 miles away. Afterward, Margaret Ralph was among those crying tears of joy. Asked what she'll say when she sees Knox, Ralph told KOMO, "I won't say anything. I'll just give her a big hug and kiss." "It was incredible," fellow supporter Kellanne Henry told KOMO, adding that it took a minute to absorb the news. "They finally got it right," she said. Many Seattle residents took to social media to post messages. "I am so happy this nightmare is over for you," Seattle resident Jenn Whitney wrote in a posting on one of several Facebook pages devoted to Knox. Whitney said she "cried with joy" when Knox's conviction was overturned. "I pray that God brings you home safely," she added. "If I had the chance to greet her when she lands back here in Seattle, the only thing I would do is hand her a rose, give her a hug and say 'welcome home!' " Jeff Bamby posted. On another Facebook page, Tamara Slater wrote, "Amanda you have been in the prayers of so many people, it must be heart warming to know you were never forgotten. Welcome home!" CNN affiliate KIRO-TV reported that when staff went out to gauge reactions to the news out of Italy on Monday, "We met just a few people in West Seattle who disagreed with Monday's ruling and thought that Knox was guilty." Jordan Adams said he thought Knox was guilty, but he was willing to accept the decision to overturn the conviction. "I did think she was guilty, but I guess, good luck to her since she's been freed and cleared," he told KIRO. Early Tuesday morning, a jogger who spotted a CNN crew in Seattle's Queen Anne Hill neighborhood stopped and yelled, "Yay Amanda! Welcome home!" But later, another resident walked up to a CNN crew to say that she could not "care less about Knox returning home" and that she believed Knox committed the crime. CNN's Josh Levs and Sandra Endo contributed to this report.

[Q]: BUENOS AIRES, Argentina (CNN) -- More than 10,000 charred bone fragments were found buried at the site of a former Argentine government detention center, the first find of its kind at one of the secret centers, Argentine officials said. Bones were unearthed during a seven-month search at an ex-detention post in La Plata, Argentina, officials said. Searchers said they also found a wall with more than 200 bullet holes and an "important quantity" of spent ammunition shells on the ground nearby. In some cases, bullets were still lodged in the wall. The announcement was made Tuesday at a news conference by government officials and representatives of the Argentine Forensic Anthropology Team, better known as EAAF, the initials of its name in Spanish. A team of six professional anthropologists and support crew said it believed the remains were human, but it was unable to determine how many bodies the fragments represented. "I ask the forgiveness of family members, because I can imagine what the mothers and all who are gathered here will feel, but what we are about to show is not to detail the genocide but so that we have proof for the trials that are to come," said Sara Derotier de Cobacho, secretary of human rights for Buenos Aires province. "But let us not forget," she said in a statement, "that behind every clandestine center there were the names of the repressors. ... So it is very important for all citizens to know those names." The detention center was among those used in Argentina during the country's "Dirty War," which started in 1976 when a group of generals staged a coup and started a vicious crackdown against anyone considered a subversive. By the time civilian control of the government resumed in 1983, up to 30,000 Argentines had been abducted and taken to the secret government detention centers, where they were tortured and killed. They are widely called "los desaparecidos," or "the disappeared." Thousands more people were abducted and killed by right-wing dictatorships in other South American countries during the 1970s and 1980s, particularly in Chile and Uruguay. The bone fragments in Argentina were unearthed during a seven-month search at the former detention post in the city of La Plata, near Buenos Aires. In 25 years of searching, this was the first time that human remains were found at a former detention center, said Luis Fondebrider, president of the EAAF. "We've worked throughout the country and have always found remains in cemeteries, never outside," Fondebrider said in the release. The conference was called, he said, because of the extraordinary nature of the find. "We usually don't hold press conferences about our work or what we find," Fondebrider said. "But we understand that the magnitude of what we have found where the Clandestine Center of Arana was located merits that sometimes we show partial results." The searchers determined that bodies had been burned inside graves along with tires, combustibles and other material, Fondebrider said. "The possibilities of identifying some of these remains is low because of the state they are in," Fondebrider said. The searchers will start analyzing the remains next year and are working with two prominent forensic genetic laboratories that specialize in working with remains that are in poor condition, he said. Lending an official air to Tuesday's proceedings, Carlos Stornelli, minister of security for the province of Buenos Aires, and Pablo Buruera, mayor of La Plata, also attended the news conference. "We are looking for the truth so we can attain justice and construct, from there, the memory of our 30,000 'desaparecidos,' " Derotier said.
