PORTLAND — A Sanford man has been convicted of making and distributing child pornography involving an infant.

Federal prosecutors say 32-year-old Royce Breton was convicted Thursday after a four-day trial.

Prosecutors say Breton produced the pornography, then distributed it via an online messenger service. More than 300 images of child pornography were found on a computer in his home.

Sentencing was not immediately scheduled. Breton faces anywhere from 15 to 30 years in federal prison on the production charge, five to 20 years for the distribution charge and up to 10 years on the possession charge.
