Investigators trying to solve the mystery of a census taker found hanging from a tree with the word “fed” scrawled on his chest are examining whether he manipulated the scene in order to conceal a suicide and make a life insurance claim possible for his son, law enforcement officials told The Associated Press…

Sparkman, 20, who is unemployed, said he’s convinced his father could not have committed suicide, even though law enforcement officials previously told the AP on condition of anonymity that they were looking closely at that possibility and increasingly doubted he was killed because of his government job, as was first feared.

There were no defensive wounds on Bill Sparkman’s body, and while his hands were bound with duct tape, they still were somewhat mobile, suggesting he could have manipulated the rope, the officials said. He was found hanging from the tree yet was in contact with the ground. Homicide, suicide and an accident were all being considered as a manner of death, authorities said.
