The whole country was on high alert when two explosions rocked the Boston Marathon. Details have emerged pitting brothers Tamerlan and Dzhokhar Tsarnaev as the suspects behind the bombs planted near the race’s finish line. The case has been quickly unwinding, as Tamerlan Tsarnaev was killed in shootout with police and Dzhokhar Tsarnaev is in custody with charges filed against him. The whole incident hasn’t been unwinding so quickly, however, for Michigan State University Human Resources and Labor Relations graduate student Cody Harlacher, who was a participant in the marathon. “I actually kind of shut down completely,” Harlacher said.
