The sentencing hearing has been delayed for a Brentwood man who extorted sexually explicit cellphone images from teen girls using information he downloaded from the cellphone of a female relative.

Friday's sentencing of Russell Freed, 41, in Pittsburgh was postponed indefinitely because of a last-minute medical issue.

Prosecutors want a federal judge to sentence Freed to far more than the 15-year minimum sentence he faces for posing as a young woman and blackmailing teen victims through their Facebook pages.

Freed's attorney said his client didn't realize the girls who sent him pictures were minors. The attorney said Freed contacted the teens using the discarded cellphone of a 21-year-old female relative and assumed that woman's "contacts" were also about that age.

Authorities said the girls' pages made clear they were students.
