A Redding man will be locked up for more than a decade for distributing child pornography. Between June and November of 2012 investigators with the U.S. Department of Justice “Project Safe Childhood” detected a computer in the Redding area that was making child porn available over a peer-to-peer file sharing service. The electronic trail led to 64-year-old Michael Ray Robertson. A search of his home turned up a computer containing many images and videos showing the sexual exploitation of children. In March of this year Robertson decided to plead guilty and he was sentenced Thursday to 11 years 3 months in federal prison. The case was part of a nationwide investigation in 2012 called “Operation Sunflower”. It was named for a sunflower-shaped road sign seen in the background in online photographs that helped lead to the rescue of an 11-year-old girl in Kansas. The operation resulted in more than 2 dozen arrests in Northern California alone, according to prosecutors.
