Troopers say a White Plains man had massive stash of heroin packaged for sale in his car when they pulled him over on the Taconic State Parkway Friday.

Gary Matos was heading north on the Taconic Friday afternoon when troopers spotted him speeding, a State Police investigator said.

Matos, 44, appeared intoxicated when a trooper pulled him over, and police said a chemical sobriety test revealed Matos had a blood-alcohol level more than twice the legal limit.

After troopers arrested Matos, they searched his car and found 44 ounces of heroin, individually wrapped into "bundles" of 10 bags each. Each bag is one tenth of a gram. Although police said the street price of heroin varies, the seized heroin could command a street price of tens of thousands of dollars.

Matos was charged with first-degree criminal possession of a controlled substance, the state's top-level felony charge for drug possession, as well as aggravated misdemeanor driving while intoxicated and a long list of vehicle and traffic violations.

Matos was arraigned and sent to Dutchess County Jail without the possibility of posting bail. He's scheduled to return to Town of LaGrange Court on Sept. 18.

State court files show Matos was represented by Legal Aid in New York City for an earlier arrest this year. His attorney could not be reached on Saturday.
