CENTRAL ISLIP - The wife of the man accused of killing four people at a Medford pharmacy pleaded not guilty today to charges of robbery and resisting arrest, but new information suggests that she might have been even more involved in the plot.

According to court documents obtained by News 12 Long Island, prosecutors say Melinda Brady and her husband, 33-year-old David Laffer, discussed the robbery the night before. Brady also allegedly gave her husband a legitimate prescription to use in the robbery.

Prosecutors say Brady thought Laffer would "only threaten the pharmacist to steal drugs." According to Suffolk Assistant District Attorney James Chalifoux, Brady also admitted to driving the getaway car to and from the crime scene.

In light of these revelations, Chalifoux says it's likely charges will be upgraded against Brady.

As News 12 Long Island has reported, Brady seemingly turned on her husband right after their arrests, yelling out to reporters, "He did it, he did it."

Investigators say Laffer is a prescription drug user, and Brady herself admitted to taking painkillers in a post she made on a wedding website.

A grand jury will convene Monday to consider bringing more serious charges against Brady. Her bail was set at $750,000 or a $1.5 million bond.
