Boston Marathon Bombing Trial to Begin by VOA News Boston will revisit some of its worst memories on Wednesday when federal prosecutors begin laying out their case against accused Boston Marathon bomber Dzhokhar Tsarnaev. Tsarnaev, 21, is charged with killing three people and injuring 264 with a pair of homemade pressure-cooker bombs, packed with nails and ball bearings, that ripped through thousands of onlookers crowded at the race's finish line on April 15, 2013. ''He could be sentenced to death if convicted of charges that include using a weapon of mass destruction and fatally shooting a police officer. Prosecutors told U.S. District Judge George O'Toole on Monday that they may want to show as evidence autopsy photos of the attack's victims, one an 8-year-old boy. They also want to play clips from an FBI news conference where officials released photos of Tsarnaev and his older brother identifying them as suspects and setting off a course of events that led to a daylong lockdown of most of the Boston area amid a massive manhunt. Assistant U.S. Attorney William Weinreb will lay out the prosecution's case in opening statements. Tight security The trial, which is being held under extremely tight security in U.S. District Court in Boston, is expected to be one of the most closely watched terror cases in years. Defense attorneys, meanwhile, aim to portray Tsarnaev as having been under the spell of his 26-year-old brother, Tamerlan, who they contend was the mastermind behind the attack. Tamerlan died following an April 18, 2013, gun battle with police. Attorney Judy Clarke, a well-known death penalty opponent, will deliver the opening statement for the defense. Tsarnaev, who has pleaded not guilty to all charges in a 30-count indictment, was arrested, seriously injured and hiding in a boat in Boston suburb on April 19, several hours after his brother died. He is being held in near-solitary confinement in federal prison outside Boston, where his visitors and contact with the outside world are strictly limited to immediate family and his legal team. Prosecutors say the brothers, both of part Chechen descent, built their bombs based on instructions in Al-Qaida's English-language magazine Inspire but that they appear otherwise to have acted alone. An all white jury of eight men and 10 women was sworn in Tuesday, capping a two-month selection process delayed by historic snowfall in the city and repeated attempts to move the trial elsewhere. Trial begins District Judge George O'Toole has rejected all attempts to move the case, as has the Court of Appeals for the First Circuit, paving the way for opening statements to begin in the trial at 9:00 a.m. (1400 GMT). Some victims and relatives have voiced determination to attend the three to four-month trial. Tsarnaev supporters are also expected to gather outside, after O'Toole refused to ban them, following the defense's claims that wild conspiracy theories many of them espouse could taint their client. The trial is expected to last three to four months. A replaying of some of the graphic evidence of the attack could trigger fears among people who lived in the area during the bombing week, said Alice LoCicero, a Boston Medical Center psychologist who has researched the psychology of terrorist attacks. "What people might anticipate is a return of some of the same feelings that they had at the time of the initial bombing," LoCicero told Reuters. "A lot of fear may be associated with reliving some of those events." The bombing killed restaurant manager Krystle Campbell, 29; graduate student Lingzi Lu, 23, and Martin Richard, 8. Massachusetts Institute of Technology police officer Sean Collier, 27, was fatally shot three days later. Material for this article came from Reuters, AP and AFP.
