(HUDSON POLICE DEPARTMENT) Enlarge photo HUDSONâ€”The attack and robbery of an elderly woman at a Petco parking lot last week angered police officers. "It was one of those crimes where everyone in the department said, "We want these two,'" said Police Chief David A. Stephens. Officers were happy to learn that two people were taken into custody for the crime. Both are due to be arraigned today in Marlboro District Court. Two sisters face charges in the Wednesday night robbery outside the Petco on Washington Street. Police were called to the Petco around 6:45 p.m. Wednesday and found an 81-year-old Marlboro woman in pain and disorientated. The victim told officers she was loading items into her car when another woman approached her. The woman started up some small talk about the holidays, and then she suddenly pushed the victim and snatched her purse, according to Chief Stephens. The woman was not seriously injured. The assailant ran off, with some patrons following, but soon disappeared. "My guys were tenacious on this," the chief said. "Think of the shock and disbelief that goes through that victim's mind as this is happening to them." Investigators learned the victim's credit card was then used at the Walmart in Hudson. A flat-screen television and household items had been bought. Hudson police retrieved video surveillance images of the suspects and began distributing the information to other law enforcement departments. Officers from Framingham gave Hudson police tips on the identity of the women. Police were able to get enough information to obtain arrest warrants. Hudson Sgt. Chad Perry headed to 50 Briarwood Lane, Apt. 1, in Marlboro to locate the suspects. A woman at the apartment matched the picture of one of the suspects. Lizette I. Nevarez, 47, of 11 Creighton St., Apt. 410, Jamaica Plain, was charged with accessory after the fact, conspiracy, credit card fraud over $250, larceny over $250 by a single scheme and credit card larceny over $250. As Sgt. Perry was arresting her, the phone inside the apartment began to ring. Lizette Nevarez asked him to answer the phone. Her sister, Anna M. Nevarez, 40, of 50 Briarwod Lane, Apt. 1, Marlboro, was on the line. Sgt. Perry simply told her about the arrest warrant. Anna Nevarez agreed to go to the Hudson police station, where she was charged with unarmed robbery of a victim over 65, assault and battery on a victim over 65 resulting in injury, larceny of a credit card, credit card fraud over $250, conspiracy and larceny over $250 by a single scheme. Police obtained a search warrant for the apartment and found the television and other items purchased with the victim's credit card, Chief Stephens said. "I took it personally," he said. "I told my guys, leave no stone un-turned. Do what you normally do but make that extra effort. They do great work all the time, but they made the extra effort."
