A 47-year-old Wichita man has been sentenced to 6 years in federal prison for possessing child pornography, authorities said.
Matthew Alter pleaded guilty to one count of the offense. Prosecutors told the court at a plea hearing that Alter became the subject of an investigation after Italian State Police provided information that a computer used in Kansas was accessing a child porn website.
Investigators followed an electronic trail to Alter’s home in Wichita, where they served a search warrant and seized computer hard drives containing child pornography. Photographs showed children ranging from 1 to 12 years old.
During the course of the investigation, authorities learned Alter had been collecting child pornography for 11 years. At his sentencing, Alter disputed the contention by prosecutors that he possessed approximately 1 million images of child pornography. The number, he said, was probably between 300,000 and 400,000.
