The wife of a man police say went on a cold-blooded rampage inside a Long Island pharmacy in a quest for prescription drugs, played a bigger role in the gruesome crime than first thought, court documents revealed Friday.

According to authorities, Melina Brady told police the couple's intention on that fateful Sunday morning was just to rob the Medford Pharmacy, not to commit murder. Instead on June 19 at around 10 a.m., David Laffer walked into the Haven Drugs store and opened fire, killing the pharmacist, a clerk and two customers.

A criminal complaint also revealed Brady even gave Laffer her painkiller prescription to make sure he stole the right pills.

The new details surface just a day after the couple pleaded not guilty to numerous charges including murder and robbery. Although Brady maintains she did not drive the getaway car, court papers tell a different story.

"[Brady] knowingly went with the accomplice to rob the pharmacy and drove the getaway car," read a criminal complaint released Friday.

In wake of the disturbing new information, Prosecutor James Chalifoux reportedly told the court that charges against Brady will more than likely be upgraded.

Brady was charged with second-degree obstructing governmental administration and third-degree robbery while Laffer was hit with first-degree murder and resisting arrest charges. Both remain behind bars.

According to authorities, Laffer is accused of entering the Haven Drugs Pharmacy where he gunned down pharmacist Raymond Ferguson, 45, clerk Jennifer Meija, 17, and customers Jaime Taccetta, 33, and Bryon Sheffield, 71, early Sunday morning.

In the evening on Friday, a community that has spent a week in mourning, came together for candlelight vigil in Baldhill. As many reflected and shed tears, others talked about Brady's role during Sunday's rampage, "She knew what she wanted. She was in it. I would say she was right behind him pushing it," said one attendee.

Charlie Chierchio who attended with his daughter added, "It doesn't surprise me, a criminal is a criminal no matter which way you look at it."

Yoleanda Maris who has been following the developments closely all week felt that Brady was just as responsible as her husband, "She was just as guilty and she should get the max just as he should."
