RIVERHEAD, N.Y. –  A New York woman accused of driving the getaway car after a pharmacy massacre has pleaded not guilty to robbery.

Four people died in the Father's Day prescription drug robbery in Medford on Long Island.

Melinda Brady now faces a first-degree robbery charge, which carries up to 25 years in prison if she's convicted. She had previously been charged with third-degree robbery.

The judge ordered her held without bail on Tuesday.

She'd been jailed on $750,000 bail since she and her husband were arrested last month. Brady said in a police statement that she and her husband, David Laffer, plotted the robbery, but she did not know the plan involved killing.

Laffer faces first-degree murder charges.
