Police captured Boston Marathon bomber Dzhokhar Tsarnaev from his hideout in a boat in a dramatic hail of bullets, but that was just the beginning of their work.
Less exciting, but just as important, was the task of combing through at least 30 electronic devices seized in connection with the investigation into Dzhokhar and his brother Tamerlan Tsarnaev, who was killed in a previous shootout following the 2013 bombing that killed three and injured more than 260. Those devices included seven computers, 10 external hard drives and 13 cellphones, containing more than 20,000 pieces of data.
