BOSTON - A funeral director who was sharply criticized for handling funeral arrangements for Boston Marathon bombing suspect Tamerlan Tsarnaev is writing a book about his experience.

Peter Stefan -- the director of a funeral home in the central Massachusetts city of Worcester -- says he received thousands of angry phone calls and threats from people who called his decision "un-American."

Stefan took responsibility for Tsarnaev's remains after another funeral home was picketed. Stefan's funeral home also was picketed, and it took days to find a cemetery willing to bury Tsarnaev, who died in a shootout with police. His body was finally buried in a Muslim cemetery in Virginia.

Stefan says he is negotiating with a publisher.

Tsarnaev's younger brother, Dzhokhar, is awaiting trial in the 2013 bombing.
