Nine people, including a 47- year-old mother and her four sons, were arrested after police seized drugs, cash, weapons and other items from a Pelham house.

Police raided the 13 William Drive residence around 9:45 p.m. on Thursday, Jan. 4, following a two-month long investigation into the sale of marijuana and Oxycontin in town.

During the investigation, the house was sometimes under surveillance.

Neighbors had complained to police about traffic at the house, said Sgt. Michael Pickles.

“Cars were coming and going all hours of the day, different hours of the night,” Pickles said.

“(Neighbors) noticed cars were stopping for a short time and leaving.”

Police executing a search warrant at the house seized a half-pound of marijuana with a street value of $1,500; 20 marijuana plants in different stages of growth; approximately $4,000 in cash; distribution items, such as plastic bags, scales and how-to manuals; bongs and pipes; prescription pills; pellet guns and a machete.

One of the sons, David Perry, 24, faces the most serious charges: three felony counts of sale of Oxycontin, possession of Oxycontin, possession of marijuana with the intent to distribute, manufacturing marijuana, and possession of marijuana.

His mother, Catherine Perry, 47, is charged with possession of marijuana. Two others sons, Robert Perry, 21, and Kevin Perry, 20, are each charged with possession of marijuana and transporting marijuana.

The fourth son, Paul Perry, 17, is charged with unlawful possession of prescription drugs. Jessica Fili, 22, 13 William Drive, is charged with possession of marijuana and manufacturing marijuana. Pickles described her as David Perry’s ex-fiancee, who broke off her engagement to Perry the day after being arrested.

The three others, who Pickles described as friends of the family who were frequently at the house, are: Young Kim, 21, of 78 Appleleaf Drive, who is charged with possession of marijuana; Richard Bedard, 24, of 8 Bedard Ave., who is charged with possession of Oxycontin with intent to distribute and possession of Oxycontin; and Derrick Perez, 20, 36 Hobbs Lane, who is charged with internal possession of alcohol, a violation.

David Perry was held in county jail on $20,000 cash bail. The others were released on personal recognizance bail and will be arraigned in Salem District Court on Jan. 22.

Police said that throughout their investigation, they confiscated approximately 25 80 mg tablets of Oxycontin, which has a street value of roughly $2,000.

As a result of the arrests, police said, the flow of Oxycontin – a powerful pain reliever that can be dangerously addictive when abused – in the Pelham area has likely been disrupted.

Pickles said he hopes young people will get the message that police are watching out for Oxycontin distribution.

“It’s amazing how much is going on with the pills and the younger people,” he said.
