A Worcester funeral home director is pleading for government officials to use their influence to convince a cemetery to bury Boston bombing suspect Tamerlan Tsarnaev, but so far no state or federal authorities have stepped forward to help out. “We have a body for burial that has caused a lot of controversy and we can’t continue to play this game,” said Peter Stefan, owner of the Graham, Putnam and Mahoney Funeral Parlors. “Under normal circumstances, the government would say it’s (the funeral parlor’s) responsibility to find a place for burial, but this is not normal circumstances. This is a nightmare.”
