A former Avon police trainee will serve 9 years in prison.
34-year-old Casey Medina of Rochester was convicted of federal cyberstalking and child porn charges.
Prosecutors say he had over 360 images of child porn on his phone.
Some of those images were violent.
He also superimposed a victim's face on some other pornography and sent it to various social media platforms.
He also sent messages to that person, threatening kidnap, rape, and sexual assault, and recruited others to do the same.
