(06/20/11) - The shooting deaths of four people at a Medford pharmacy yesterday has local drugstores on edge, afraid the still-at-large killer might strike again.

Howard Levine, executive director of the Long Island Pharmacist Society, says security alone won't stop an addict who wants to get his hands on a medication.

Levine says legislation is needed to further restrict the availability of drugs such as Oxycodone.
