An Omaha man has been sentenced to six years in federal prison for receiving and distributing child pornography.

U.S. Attorney Deb Gilg says 47-year-old Michael Abraham was sentenced Monday. Abraham must also register as a sex offender and remained under supervised release for seven years after his release.

There is no parole in the federal court system.

Abraham was arrested following an undercover investigation by the Nebraska State Patrol and the FBI’s Cyber Crimes Task Force. Officers discovered child pornography being shared online from a computer in Abraham’s home. On Sept. 21, a search warrant was executed at Abraham’s home and turned up more than 100 videos and 50,000 images of child pornography and child erotica.
