The Springfield News-Leader reports that 30-year-old Anthony Cotter was sentenced last week for receiving and distributing child pornography. Cotter admitted to sexually abusing a girl and taking explicit photos of her. The U.S. attorney’s office says photos of the abuse and other child porn were found on his electronic devices.

Federal prosecutors say the chat group he led had about 50 members. They shared child porn of victims as young as infants.
