Alina Margulis, 45, of Brooklyn, N.Y., surrendered Monday morning, police said, and was indicted by a Baltimore County grand jury on charges of conspiracy to distribute "schedule II" narcotics.
Police said she appeared before a Baltimore County Circuit Court judge, and bail was set at $50,000 cash.
The judge also ordered her to surrender her passport and remain within the U.S.
Margulis had been sought in connection with the U.S. Drug Enforcement Administration's raid on May 15 at the Healthy Life clinic in the 1100 block of York Road, Lutherville/Timonium.
Last week, about 25 county narcotics officers and DEA agents executed federal search warrants at the clinic in the 1100 block of York Road
Two other suspects were arrested last week. Gerald Wiseberg, 78, of Boca Raton, Fla., and Michael Jacob Reznikov, 51, of Brooklyn, N.Y., were indicted by a grand jury on charges of conspiracy to distribute "schedule II" narcotics after the DEA investigation into alleged distribution and sale of Oxycodone and other prescription drugs.
Their bail was also set at $50,000, cash, and the judge also prohibited Wiseberg and Reznikov from traveling outside the U.S. pending trial.
Police said these three suspects, as well as any others who may be charged in connection with this case, may face federal charges as well Maryland charges.
The raid followed a long-term investigation, according to Special Agent Edward Marcinko of the DEA. Police said yesterday that the Healthy Life clinic has been the focus of an investigation by Baltimore County Police and the U.S. Drug Enforcement Administration since April 2011.
No additional arrests are expected at this time, police said, but the investigation will continue.
Marcinko said the DEA agents involved were members of the federal agency's "tactical diversions squad."
"Prescription fraud and prescription abuse is a very serious problem in the United States, and across the United States the DEA developed groups to handle these types of cases," Marcinko said.
