STATEN ISLAND — A Staten Island man is accused of masquerading as a clinical psychologist and medical doctor for almost three years, proving so-called treatment to more than 100 patients in his parents’ basement, the Richmond County District Attorney's Office said Friday.

The office of Donald R. Lee-Edwards looked like a little shop of horror with needles, blood vials, and medical equipment all crammed into a tight space -- the basement of his parent's home on Gordon Street.

Investigators claim the 43-year-old treated patients, took blood and urine samples and even faked lab test results. Edwards allegedly took co-pays and prescribed medicine, as well.

Prosecutors say he never completed any medical school, but told his patients a list of lies saying not only that he was a doctor but a lawyer and often discussed patient information with other patients.

He was caught in a surveillance sting Wednesday and now that he’s in jail, the Richmond County District Attorney wants to talk to anyone who’s ever met him because they could be at risk.

If you’re wondering how Edwards patients could get medication, it's alleged that the fake doctor would call pharmacies himself and they would believe he’s real and hand over the medicine. None of those pharmacies as of now are being investigated.

Edwards is being held on $150,000 bail. He's due back in court on Sept. 18.
