An Orange County doctor could have spent the rest of his life in prison for trafficking pain medicine. Instead, he made a deal that allows him to continue to treat patients and write prescriptions.

Before Sue and Alan League lost their son Jimmy to an accidental overdose three years ago, they said they saw firsthand the amount of pills he would get from doctors including Dr. Roman Mosai.

"A hundred oxycodone, a hundred Xanax bars and a hundred soma, which is a muscle relaxer," said Alan League.

The Leagues  said they turned over prescription bottles to police and were shocked to hear to Mosai reached a plea deal keeping him out of jail and practicing medicine.

Mosai's attorney explained to WFTV's Nancy Alvarez how he defended his client against drug trafficking charges that could've sent the doctor to prison for life.

"This was not a high volume pill mill operation where people were lurking in parking lots," said attorney Robert Leventhal.

Leventhal said Mosai was targeted by investigators after a former patient was caught selling drugs she stole from another of Mosai's patients. Leventhal says his client is only guilty of believing people who told him they were in serious pain.

"He's very gentle, very quiet," said Leventhal. "He's not suspicious enough. He is now."

The Leagues said any changes Mosai makes to his practice now are too late for their son.

"The doctor enabled him to have the quantity of pills he had. We have to go on without our son. Our grandchildren have to go on without their dad," said Sue Leventhal.

The current plea deal calls for Mosai to remain on probation for 20 years, and it requires him to keep a log of the prescriptions he writes. The Department of Health will also keep him on probation with them for the next three years.
