Felix A. Perez, 53, nicknamed "Felo," and his 24-year-old namesake son, Felix "Junito" Perez, 24.
They were two of the biggest cocaine dealers in Nashua, police charge, moving at least a couple kilos a month. Until their recent arrests, both lived in an apartment at 3-25 Burns Hill Road, Hudson
Then there's Felo's younger brother, Manuel Perez, 47, also known as Rolando, and his girlfriend, Aideliz Quiles, 21, both of 2 Ash Court. They were two of the biggest heroin dealers in the city, police said.
"They were the top end dogs for the city of Nashua," Detective Lt. Scott Hammond said in announcing the arrests Friday.
Police arrested Manuel Perez and Quiles last week. Felix Perez, the younger, was arrested earlier last month, and his father was picked up in November. Police held off on announcing the arrests because the investigation remains ongoing, in both directions of the supply chain, Hammond said.
"Things are in motion," he said.
The federal Drug Enforcement Administration is looking into where the Perez brothers bought their heroin and cocaine, Hammond said. He declined to comment on that end of the business, except to say it was out-of-state.
The brothers each supplied a regular group of mid-level drug dealers in the Nashua area, and police are looking into them as well, Hammond said.
"We are still conducting an active investigation into the people they were dealing with," he said.
The Perez brothers kept their two lines separate, Hammond said. Manuel Perez sold heroin, and only heroin. Felix A. and Felix J. Perez sold cocaine and nothing but cocaine, he said. It was more profitable that way, he said.
"They do this on purpose," Hammond said. "They split the business so they don't take each other's business."
Each one of the four defendants is currently jailed on state drug charges, but the cases ultimately will be prosecuted in federal court, Hammond said.
"Additional charges will be brought forward on all of them," he said.
Police also are investigating in the hope of locating any assets that they can grab under drug forfeiture laws. The family lived in rental properties, and their vehicles weren't worth taking, Hammond said.
Police and the DEA worked on the investigation together, with the feds bringing funding, agents and equipment that made it all possible, Hammond said.
Tips from citizens and drug addicts led police to the drug ring,
Drug dealing in Nashua tends to be a furtive, indoor affair, Hammond said, and open dealing on the streets is rare. Dealers typically won't even sell to strangers, without an introduction from someone they already know, he said.
Still, police were able to buy heroin and cocaine directly from all four defendants, he said.
Police found more than 150 grams of heroin, roughly $15,000 worth, when they searched 2 Ash Court on Jan. 25, and they seized more than 20 ounces of cocaine, about $50,000 worth, from purchases and searches involving Felix A. and Felix J. Perez.
