( CNN ) Opening statements in the trial of accused Boston Marathon bomber Dzhokhar Tsarnaev likely wo n't begin Monday as originally planned , because jury selection is taking longer than anticipated , a court official said Thursday . Monday `` is not realistic '' as a start date , and the court expects to announce a new date next week , said Ginny Hurley , spokeswoman for the U.S. District Court in Boston . Jury selection began more than two weeks ago . Authorities accuse Tsarnaev and his older brother , Tamerlan , of planting two pressure-cooker explosives , hidden in backpacks , near the finish line of the Boston Marathon on April 15 , 2013 . Three people were killed and more than 260 others wounded in the explosions . Three days later , after the FBI released surveillance photos of the suspects , the Tsarnaevs shot and killed Massachusetts Institute of Technology police officer Sean Collier , authorities say . Early the next day , Tamerlan Tsarnaev died of wounds he suffered during a shootout with police , and Dzhokhar Tsarnaev was found and arrested that night , hiding in a boat behind a house . Dzhokhar Tsarnaev was charged with 30 federal counts , including using a weapon of mass destruction resulting in death and malicious destruction of property by means of an explosive device resulting in death . He pleaded not guilty in July 2013 .
