MUSKEGON, Mich. (NEWSCHANNEL 3) - Muskegon County Sheriff's are looking for more possible victims of a Casnovia man they say was part of a nationwide child pornography group.

Kevin Charles Miller was in court Thursday to answer to three counts of first degree criminal sexual conduct.

The six-year-old victim was reportedly identified from photographs on Miller's computer. Authorities say they confiscated tens of thousands of photographs, some shot by Miller himself. It's not known how many of those may be local children.

The FBI is also investigating and more charges are expected. Anyone with information is asked to call the Muskegon County Sheriff's Department.
