Dr. Joseph Campbell reported Wednesday that 39-year-old Darius Hill was shot six times Monday evening.
But Campbell says one of the wounds was self-inflicted and he does not know conclusively which one caused Hill's death.
Bucks County District Attorney Michelle Henry says the shooting is being investigated. She says the federal warrant was for investigation into possession and distribution of child pornography.
FBI spokeswoman Jerri Williams says an earlier statement that a coroner's report showed Hill had shot himself was premature. She says the FBI is conducting an internal investigation into the shooting. Bucks County detectives are also investigating.
