Peter (surname unknown) is a pharmacist and the silent partner of drug dealer Dr. Eliza Glazer. Peter overprescribed oxycodone for Glazer, who used her job as a cosmetic dermatologist as a cover.
When Glazer was murdered, Peter was tracked. He denied the murder and was cleared of that charge, but his legal status for his drug crimes was left unknown, (L&O: “Oxymoron”)
