His death is still a mystery, more than a month after his body was found.
But Monday night, friends and family said their final goodbyes to a U.S. Census worker.
Bill Sparkman's body was found near a Clay County cemetery last month.
His death has received national attention.
Law enforcement officials say there was a rope around Sparkman's neck, and the word "Fed" written on his chest.
Police have not yet determined if Sparkman's death was a homicide, accident, or suicide.
Sparkman's service took place at the First United Methodist Church in London.
