BOSTON (AP) — Prosecutors and defense attorneys on Wednesday made their final appeals to the jury that will decide the fate of Dzhokhar Tsarnaev as jurors began deliberating whether the Boston Marathon bomber should get life in prison or the death penalty. 
 
 "The choice between these very serious alternatives is yours and yours alone to make," Judge George O'Toole Jr. told the panel. 
 
 Jurors must be unanimous in their decision to impose the death penalty. If even a single one votes against death, Tsarnaev will get life in prison. 
 
 Prosecutor Steve Mellin said Tsarnaev wanted to cause his victims as much physical pain as possible to make a political statement. 
 
 "The bombs burned their skin, shattered their bones and ripped their flesh," Mellin said. The blasts "disfigured their bodies, twisted their limbs and punched gaping holes into their legs and torsos." 
 
 "Merely killing the person," he said, "isn't nearly as terrifying as shredding them apart." 
 
 Defense attorney Judy Clarke asked jurors to spare Tsarnaev's life, saying her client "is not the worst of the worst, and that's what the death penalty is reserved for." 
 
 She asked jurors to hold open their minds and try to understand how and why Tsarnaev became involved in the plot. 
 
 "We think that we have shown you that it's not only possible, but probable that Dzhokhar has potential for redemption," she said, adding that he was "genuinely sorry for what he's done." 
 
 The prosecutor showed a large photograph of 8-year-old Martin Richard, who was killed in the attack, and other children standing on a metal barricade near where Tsarnaev placed his bomb. Another photo showed bloodied victims on the sidewalk. 
 
 "This is what terrorism looks like," Mellin said. 
 
 Tsarnaev, he said, showed no regret after the bombings, calmly going to buy a half gallon of milk 20 minutes later. 
 
 "He acted like it was any other day. He was stress-free and remorse-free," Mellin said. "He didn't care because the death and misery was what he sought that day." 
 
 During the four-month trial, prosecutors portrayed Tsarnaev as a callous, unrepentant terrorist who carried out the deadly attack with his radicalized older brother, Tamerlan. 
 
 From the start, Tsarnaev's lawyers admitted he participated in the bombing, but they told the jury he was "a good kid" who was led astray by Tamerlan, who wanted to punish the U.S. for its actions in Muslim countries. 
 
 Clarke said Tsarnaev's parents favored his older brother and pinned their hopes on him, believing he would become an Olympic boxer. She showed photos of his father at boxing matches with Tamerlan, then asked "Where are the pictures of Dzhokhar? He was the invisible kid." 
 
 She noted the testimony of one witness who said the younger Tsarnaev followed his older sibling around "like a puppy." 
 
 Tamerlan was a "jihadi wannabe" who returned to the U.S. angry and frustrated after an unsuccessful attempt to join Islamic extremists in Russia, Clarke said. Then he decided to find another way to wage jihad. 
 
 "If not for Tamerlan, this wouldn't have happened. Dzhokhar would never have done this, but for Tamerlan. The tragedy would never have occurred but for Tamerlan — none of it," Clarke said. 
 
 Mellin dismissed the contention that the older Tsarnaev somehow led his brother down the path to terrorism. "They were partners in crime and brothers in arms. Each had a role to play and each played it," he said. 
 
 Three people were killed and more than 260 injured when two bombs exploded near the marathon's finish line on April 15, 2013. 
 
 Tsarnaev, 21, was convicted by a federal jury last month of all 30 counts against him, including use of a weapon of mass destruction. The same jury must now decide his punishment. 
 
 Defense lawyers have said a life sentence would also help the families of his victims, who would not be subjected to the years of appeals and public attention that would almost certainly follow a sentence of death. 
 
 The defense showed the jury photos of the federal Supermax prison in Florence, Colorado, where Tsarnaev would probably be sent if he gets life. There, his lawyers said, he would be locked in his cell 23 hours a day — a solitary existence that would deny him the martyrdom he apparently sought. 
 
 A sentence of life "reflects justice and mercy," Clarke said. Mercy "is never earned. It is bestowed, and the law allows you to choose justice and mercy." 
 
 She disputed prosecutors' characterization of Tsarnaev as unremorseful. She cited testimony of Sister Helen Prejean, who said Tsarnaev told her he was sorry about the pain and suffering victims endured. 
 
 "What unrepentant, unchanged, untouched jihadi is going to meet with a Catholic nun?" she said. 
 
 Mellin reminded jurors that some of them — before they were chosen for the jury — expressed a belief that a life sentence may be worse than death. 
 
 "This defendant does not want to die. You know that because he had many opportunities to die on the streets of Boston and Watertown. But unlike his brother, he made a different choice," Mellin said. "A death sentence is not giving him what he wants. It is giving him what he deserves." ||||| Boston (CNN) Jurors resumed deliberating Thursday morning whether Boston Marathon bomber Dzhokhar Tsarnaev should spend the rest of his life in prison or be executed for his role in killing four people and wounding dozens more. 
 
 The jury was given the case Wednesday afternoon following attorneys' closing arguments. The prosecution told jurors Tsarnaev was a remorseless terrorist worthy of the death penalty, while the defense said he was repentant and deserved to be spared. 
 
 "The defendant knew what kind of hell was going to be unleashed," prosecutor Steve Mellin said. 
 
 Defense attorney Judy Clarke countered: "We're asking you to choose life. Yes, even for the Boston Marathon bomber." 
 
 U.S. District Court Judge George O'Toole sent the jury out shortly after 4 p.m. Wednesday. "The importance of your deliberations is obvious," he said. About an hour later, jurors were sent home for the night. 
 
 "You have a long way to go," the judge told them before reminding them to avoid any outside information or discussion about the case overnight. 
 
 Tsarnaev, who is 21, was convicted in April of 30 counts; 17 of them carry a possible death sentence. He was found guilty of conspiring and detonating weapons of mass destruction at a public event as an act of terrorism resulting in death. 
 
 Jurors will complete a 24-page questionnaire that asks them to weigh "aggravating" factors presented by the prosecution and "mitigating" factors advanced by the defense before making a final decision on life or death for each of the 17 counts. 
 
 O'Toole earlier reminded jurors they have to be unanimous to return a death sentence and that no juror is under any obligation to choose death. 
 
 Hoping to spare Tsarnaev's life, defense attorney Clarke told jurors in her closing argument that her client has shown repentance and is "not the same angry young man the prosecution has described to you."

 "He'll have no glory or stature that martyrdom will bring. His name will fade from the headlines. It will fade from the news altogether and those who so desperately no longer want to be reminded of him." 
 
 Clarke made her plea shortly after the prosecution told jurors Tsarnaev was a terrorist whose actions "have earned him a sentence of death." 
 
 Prosecution: 'What terrorism looks like' 
 
 In his closing argument, prosecutor Mellin showed gruesome images to remind jurors of the carnage unleashed on April 15, 2013 , stating: "This is what terrorism looks like." 
 
 Mellin then named the three people killed in the bombings carried out by Tsarnaev and his older brother, Tamerlan Tsarnaev, who was killed in a shootout with police. 
 
 Martin Richard , 8: "Bleeding in agony, while his mother bends over, injured in one eye, begging him to live." 
 
 Lingzi Lu , 23: "Screaming in pain while she dies in that street." 
 
 Krystle Campbell , 29: "Burned all over her body, filled with shrapnel, with smoke coming out of her mouth." 
 
 He implored jurors to remember the others in the crowd or running that day who stared "in shock at their mangled and ruined limbs." 
 
 "It's hard to think of a better place to murder people than the Boston Marathon if you want to make a statement [that] you think Americans are in need of punishment," Mellin said. 
 
 The prosecutor told jurors not to forget about the fourth person killed by the Tsarnaev brothers. Sean Collier , a 27-year-old MIT security officer, was shot at point-blank range days after the bombing. 
 
 "Killing a police officer makes all of us more vulnerable." 
 
 He especially cited the vulnerability of Martin Richard, who weighed less than 70 pounds. "Can there be anybody more vulnerable than a little boy next to a weapon of mass destruction?" Mellin asked.

 "The defendant placed that bomb on the ground, so the smaller the victims were the more exposed they were to that shrapnel." 
 
 The entire Richard family was standing there, with Martin's mother, Denise Richard , suffering grave wounds and his younger sister, Jane, having one of her legs blown off. 
 
 "This defendant blinded their mother, maimed their 6-year-old daughter and blew apart their 8-year-old son in front of the father." 
 
 Mellin beat back at the defense portrayal of Tsarnaev as a good-natured kid who fell prey to his older brother and followed his orders. 
 
 "All murderers start out as cute children, but sometimes the cute children grow up to be bad people," Mellin said. "Tamerlan Tsarnaev was not his brother's master. They were partners in crime and brothers in arms." 
 
 He concluded his argument by saying "a death sentence is not giving him what he wants. It's giving him what he deserves." 
 
 "After all of the damage and carnage and fear he has caused, the right decision is clear. The only sentence that will do justice in this case is the sentence of death." 
 
 Defense: Blame the brother 
 
 In her closing argument, Clarke blamed the older brother, Tamerlan , for the radicalization of a once promising, hard-working kid. 
 
 "The story of Jahar cannot be told without knowing the story of Tamerlan," Clarke said. "How does this good kid, this youngster, this young man who was described as gentle by friends and family and teachers do this? How does this happen? 
 
 "If you expect me to have an answer, a simple clean answer as to how this could happen, I don't have it," the defense attorney said. "I can tell you this. Jahar Tsarnaev is not the worst of the worst. And that is what the death penalty is reserved for -- the worst of the worst.

 "Is his a life worth saving? Is there hope for him? Is there a chance for redemption?" 
 
 She reminded jurors of the testimony of Sister Helen Prejean, the Roman Catholic nun famous for counseling the condemned on death row. Prejean said she believed Tsarnaev was "genuinely sorry" for the pain and suffering he inflicted on his victims. 
 
 "That sounds like growth," Clarke told jurors Wednesday. "What unrepentant, unchanged, untouched young jihadi is going to meet with a Catholic nun. What unrepentant, hate-filled jihadi would even try to get her?" 
 
 Clarke is one of the nation's foremost experts on keeping clients off death row. 
 
 She has successfully fought for the lives of Ted Kaczynski, known as the Unabomber, and Jared Loughner , the gunman who killed a judge and wounded former U.S. Rep. Gabrielle Giffords in Arizona. 
 
 In the government's rebuttal, prosecutor Bill Weinreb repeatedly called Tsarnaev a terrorist and again sought to undermine the defense's portrayal of him acting at his brother's request. "Where is the evidence that he was under his brother's spell? 
 
 "The defendant deserves the death penalty -- not because he's inhuman but because he's inhumane." 
 
 He ended with: "If you sentence him to life in prison, you will be giving him the minimum punishment under law. Ask yourselves: Do these crimes deserve the minimum punishment?" ||||| Marathon bombing victim Krystle Campbell was the “light of her father’s life,” prosecutor Steve Mellin said during closing arguments in the penalty phase of the Dzhokhar Tsarnaev trial Wednesday. 
 
 “Now,” Mellin said, “that light is out.” 
 
 At any point before those two bombs exploded at the finish line on that beautiful Patriots’ Day, Tsarnaev “could have reflected, reconsidered, and stood down” from the destruction he and his brother had planned for months, he said

 Instead, Mellin said, Tsarnaev walked up behind a group of children, placed a backpack four feet behind them, and waited. Mellin paused for 20 seconds during his argument — and then told the jury that Tsarnaev waited 12 times that before walking away. 
 
 “The defendant knew what kind of hell was going to happen, that he unleashed,” he said. 
 
 That hell encompassed more than the pain the dead and wounded suffered, Mellin said. It’s the torment the survivors still feel, the families — like the Richards and the Corcorans — that were physically and emotionally “blown apart” by the events of that day. 
 
 Mellin denounced the defense team’s assertion that Tsarnaev was under his older brother Tamerlan’s sway: “Tamerlan Tsarnaev was not the defendant’s master. They were partners in crime and brothers in arms. Both decided they wanted to punish America, in a way that would win them glory and a place in paradise.” 
 
 The brothers targeted Patriots’ Day, a day in which they knew families would gather to watch the marathon, in which the world would be watching, Mellin said, and targeted innocent people. 
 
 Tsarnaev has been remorseless all along, Mellin said, buying milk right after the bombings and flipping off his holding cell’s camera months later. 
 
 “The only sentence that will do justice in this case is a sentence of death,” he said. 
 
 But in her closing argument, defense attorney Judy Clarke said the death penalty is reserved for the worst of the worst—and “Dzhokhar Tsarnaev is not the worst of the worst.” 
 
 Clarke spent much of her argument going through the circumstances that brought Tsarnaev into the plot she said originated with Tamerlan. 
 
 “The story of the Boston Marathon bombing is of a tragedy of their making, but it is more than that,” she said. 
 
 Clarke detailed Tsarnaev’s family life, from the many moves he went through as a child to his troubled parents and status as “the invisible kid,” and, finally, Tamerlan’s influential personality and radical beliefs crystallized during his 2012 trip to Russia. 
 
 “To say Tamerlan did not influence Dzhokhar defies the reality,” Clarke said, adding that, by September of 2012, Dzhokhar’s “sole source of family, of support, of strength, was his older brother.” 
 
 Tamerlan was the one who sought jihad in Russia, who sent radical Islamist materials to Dzhokhar, who had a photograph of dead children as his computer’s wallpaper, she said. 
 
 “Dzhokhar would never have done this, but for Tamerlan,” Clarke said. 
 
 According to Clarke, the government failed to prove that Dzhokhar is a hopeless case for whom the only appropriate punishment is death. According to the testimony of Sister Helen Prejean, he has even grown to show remorse for his crimes, she said. 
 
 “We think we’ve shown you that … Dzhokhar has potential for redemption,” Clarke said. 
 
 Should Tsarnaev be spared, she said, it’ll be no picnic. He’ll be sent to ADX, where Clarke said “he’ll have no glory and stature that martyrdom could bring.” 
 
 Clarke emphasized that no punishment could take back what Tsarnaev did, or even “balance the scales.” Life is prison is not a lesser punishment than death, she said—it’s just another kind. 
 
 “I ask you to make a decision of strength,” she told jurors. “I ask you to choose life.” 
 
 During his rebuttal, prosecutor William Weinreb criticized the defense’s continued focus on Tamerlan: “At times it might have seemed to you that Tamerlan was on trial.” 
 
 But at no point in the trial, Weinreb said, did the defense prove that Tamerlan made his brother commit any crimes, or brainwashed him to hold any radical beliefs. 
 
 Instead, Tsarnaev’s “actions are the best guide to the depths of his beliefs,” he said. 
 
 Despite defense testimony that Tsarnaev feels remorse, Weinreb said that it is unlikely that Tsarnaev would spend much time thinking about the bombing victims should he be sent to prison for life. 
 
 “Maybe he’ll leave behind his memories of Martin, Lingzi and Krystle the same way he left them lying on the street, bleeding,” he said. 
 
 “The defendant deserves the death penalty not because he’s inhuman,” Weinreb said, “but because he’s inhumane.” 
 
 Referring to life in prison as the minimum allowable punishment for Tsarnaev’s crimes, Weinreb asked jurors, “Does he deserve the minimum punishment, or do these crimes, these four deaths, deserve something more?” 
 
 It was the government’s last line to the jury, who are now tasked with determining Tsarnaev’s fate.

– Now Dzhokhar Tsarnaev's fate is up to the jury: either life in prison or the death sentence. Attorneys made their closing arguments today in the sentencing phase of Tsarnaev's trial, with prosecutors focusing on the carnage he helped inflict and defense attorneys on his reported remorse, the Boston Globe reports. They also sparred over whether Dzhokhar, now 21, had fallen under the spell of his older brother, Tamerlan. Among the highlights: "The bombs burned their skin, shattered their bones and ripped their flesh," says prosecutor Steve Mellin, the AP reports. The blasts "disfigured their bodies, twisted their limbs and punched gaping holes into their legs and torsos. Merely killing the person, isn't nearly as terrifying as shredding them apart." "He acted like it was any other day," says Mellin, who notes that Tsarnaev calmly bought milk 20 minutes after the bombing. "He was stress-free and remorse-free. He didn't care because the death and misery was what he sought that day." "The only sentence that will do justice in this case is a sentence of death," adds Mellin. But with a life sentence, Tsarnaev will "have no glory or stature that martyrdom will bring," says defense attorney Judy Clarke, CNN reports. "His name will fade from the headlines. It will fade from the news altogether." "That sounds like growth," says Clarke of Tsarnaev's meeting with a nun, to whom he reportedly showed remorse. "What unrepentant, unchanged, untouched young jihadi is going to meet with a Catholic nun." "I can tell you this," says Clarke. "Jahar Tsarnaev is not the worst of the worst. And that is what the death penalty is reserved for—the worst of the worst."
