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.
