BOSTON (AP) -- A Massachusetts funeral director who was sharply criticized after he agreed to handle funeral arrangements for Boston Marathon bombing suspect Tamerlan Tsarnaev (TAM’-ehr-luhn tsahr-NEYE’-ehv) is writing a book about his experience.

Peter Stefan -- the director of a Worcester funeral home -- 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 a funeral home in North Attleborough was picketed. Stefan’s funeral home was also picketed, and it then took days to find a cemetery willing to bury him. Tsarnaev was finally buried in a Muslim cemetery in Virginia.

Stefan said he has been working on the book for a few months and is negotiating with a publisher.

Tsarnaev’s brother, Dzhokhar (joh-HAHR’), is currently awaiting trial in the 2013 bombing.
