A registered sex offender from Rochester is going back to prison for 27 years.

Daryll Clark was convicted of receipt of child pornography.

Prosecutors say he met a 15-year-old girl in an online chat room and asked for sexually explicit photos and videos from her and she sent them.

Clark was on parole for a rape and sex act conviction from 2012 out of Irondequoit when the crime happened. Prosecutors say his last victim was also 15 years old at the time.
