Businesses are expected to completely reopen Wednesday along the Boston Marathon route—although the area remained haunted by the bombing that killed three and injured more than 200. “I’m a little lost,” said Charlesmark Hotel manager Leah Bishop. “I’m still shaken up.” Doors along Boylston Street on Tuesday, one of Boston’s busiest commercial streets, were still tagged by “OK” or “Locked”—the aftermath of the inspections for safety. Meanwhile, Vice President Joe Biden will speak Wednesday at the funeral of Sean Collier, the MIT campus police officer killed by the Tsarnaev brothers. Thousands of law enforcement officials are expected to attend as well.
