NEW YORK (CBSNewYork) — A husband and wife team illegally sold millions of dollars of oxycodone out of their pharmacies in Brooklyn and Queens, prosecutors said.

A six-count indictment alleges that over a period of five years, registered pharmacist Lilian Jakacki and her husband, Marcin, distributed 500,000 oxycodone pills over a 5-year period with an estimated street value of $10 million out of their pharmacies, which operated under the name Chopin Chemists.

“From 2010 to 2012 its Brooklyn location was the number one purchaser of oxycodone in the entire area covered by that zip code,” Manhattan U.S. Attorney Preet Bharara said.

While Lilian Jakacki is accused of the distribution and directing others to illegally provide the pills on fraudulent prescriptions, her husband is accused of helping to arrange the sales.

“Some pills they sold based on stolen and fraudulent prescriptions, other times they just sold oxycodone without asking for prescriptions at all,” Bharara said.

One of their most regular customers, prosecutors said, was Robert Cybulski, who has also been charged. He allegedly obtained tens of thousands of pills over the five years beginning in March 2010.

Bharara said the couple earned enough money from the sales to purchase a $2 million home in Greenwich, Connecticut.
