Boston police seize $200,000 worth of heroin, arrest Newton man

"It's a big score," said Lieutenant Detective Stephen Meade.

Meade said he could not recall a seizure that large in recent memory. The 2 kilograms would have been cut with another substance to create up to double the volume, he said, and would have been sold on the street in quarter-gram and higher quantities.

"Heroin is a huge problem in Boston and the New England region as a whole," said Meade.

Heroin use is a problem partly because some OxyContin addicts turn to it when they can no longer afford OxyContin. An average of two users overdose each day in Boston, Meade said. Most are not fatal, he said.

Meade said police did not know the extent of Avila's role in the heroin trafficking trade. Avila was charged with trafficking a Class A substance in excess of 200 grams and trafficking a Class A substance within 1,000 feet of a school zone.
