Hot on the heels of an over-the-weekend revelation that actor Corey Haim's death has been tied to an illicit prescription drug ring, the Los Angeles County District Attorney's office announced Monday that “a Los Angeles physician described as the single, most prolific provider of prescription drugs” has been convicted in an unrelated case.

Carlos Estiandan, 68, was convicted of 13 counts of unlawful controlled substance prescription following a domestic investigation by the U.S. Drug Enforcement Administration that concluded only Johns Hopkins University wrote more prescriptions than Estiandan.

“The conviction in this case illustrates a serious social problem where unethical, greedy medical practitioners aid and abet the self-inflicted harm of those addicted to prescription drugs,” District Attorney Steve Cooley states.

A sheriff's investigator went undercover and was able to receive 12 prescriptions from the man without ever being properly examined. Independently, the DEA set its sights on Estiandan after a statewide pharmaceutical-tracking system showed his prolific prescription pad use.

A judge could give him as many as 11 years behind bars at sentencing.
