PITTSBURGH — A former physician who lost his medical license over a sex-for-pills case in 2002 now faces federal prison for trying to obtain explicit cellphone pictures of a 15-year-old girl.

Robert Franzino, 61, faces a likely sentence of six-and-a-half years. Prosecutors and his attorney have agreed on the punishment, but a federal judge in Pittsburgh must still approve that when Franzino is sentenced today.

Franzino was arrested in March on charges he set up a sexual encounter with the 15-year-old. Federal prosecutors took over the case and charged him with enticing the girl into an underage sexual relationship.
