CENTRAL ISLIP, N.Y. (CBSNewYork) -- Additional charges were being considered by a grand jury Monday against Melinda Brady, the wife of the man accused of killing four people in a Medford, Long Island pharmacy last weekend.
So far, Brady is accused of only robbery and obstruction. However, prosecutors said Brady has confessed to plotting the heist at Haven Drugs Pharmacy and driving the getaway car. Last week, Brady told reporters "He did all of this. I'm sorry," in reference to her husband and suspect David Laffer.
Both Brady and Laffer have scheduled court conferences Tuesday. Both are under suicide watch with deputies saying they have shown little appetite for food in jail.
Brady, 29, is jailed on 3rd-degree robbery charges. Assistant District Attorney James Chalifoux said prosecutors may upgrade the charges against her for "her admitted role in what I submit is the most horrific crime and chilling crime in Suffolk County history."
The couple wanted to steal painkillers. Brady is said to be cooperating with authorities, but experts predict she won't be spared and that she must have known her husband was heavily armed and may have even helped Laffer with his disguise.
Criminal expert Bruce Barket spoke with CBS 2's Jennifer McLogan about additional charges that Brady could potentially face.
"She is liable for felony murder, which carries with it a sentence of 25 to life. He's liable for first-degree murder, which carries a sentence of life without possibility of parole," Barket said.
