The seven suspects still at large in the St. Lawrence County drug crime sweep Thursday have not yet been found.

A St. Lawrence County Drug Task Force member said none of the seven people sought, in addition to the 27 arrested Thursday, had been apprehended as of this morning.

"There's a lot of different officers working in the field between here and other jurisdictions" to track down the remaining suspects, St. Lawrence County Sheriff Kevin Wells said Thursday.

Wells was on hand at the press conference in Watertown Thursday afternoon led by New York Attorney General Eric Schneiderman, who announced the arrests of suspects in Pierrepont, Edwards, Massena, Canton, Potsdam, Hogansburg, Winthrop, Colton, Ogdensburg and Gouverneur.

Schneiderman said the 33 are accused of “conspiring in four loosely-related drug distribution networks that funneled heroin and cocaine across state and county lines into St. Lawrence County.”

State and local law enforcement agents, led by the New York State Attorney General’s Organized Crime Task Force (OCTF), St. Lawrence County Sheriff’s Office, the New York State Police and St. Lawrence County Drug Task Force, conducted a 12-month probe called “Operation 315” that included covert physical surveillance and hundreds of hours of wiretaps in a coordinated effort to identify and shut down heroin pipelines, Schneiderman said.

Indictments unsealed in St. Lawrence County Court on Thursday are the result of a year-long investigation in which law enforcement officials seized approximately two kilograms, or 4.4 pounds, of heroin, which has an estimated street value of $500,000. Investigators also say they seized more than five kilograms, or 11 pounds, of cocaine, with a street value estimated at $600,000, as well as over $100,000 in cash, seven hand guns, three assault rifles, two shotguns and a rifle.

The four indictments, which include a total of 111 criminal counts, charge each of the defendants with crimes that carry significant state prison time. The counts range from top felony charges of second-degree conspiracy, which carries a maximum of 25 years behind bars and first-degree criminal sale of a controlled substance, which carries a maximum of 20 years in prison, to misdemeanor criminal sale of a controlled substance.

The first indictment charges 11 defendants with distribution of heroin and cocaine. Evidence developed during the investigation and outlined in court papers, shows that Nicholas Adams of Potsdam purchased heroin in Leominster, Mass. and brought it to St. Lawrence County for distribution, where it was allegedly sold on the streets in the Potsdam area. One of his co-defendants, Laronda Ashlaw, who resided with Adams, allegedly brought heroin from Massachusetts with her toddler in a vehicle. A loaded assault weapon and hypodermic needles were seized from a closet in the child’s room. Stolen goods, including jewelry, from two burglaries were also found in the home, court papers allege.

A second indictment charges 20 people, including three who are also named in the first indictment. This indictment charges three alleged drug suppliers, one from Yonkers, one from the Bronx, and a third of Syracuse, with cocaine and heroin distribution for allegedly supplying drugs to Colin Campbell, Joshua Jones, Caleb Serrano and Jordan Willette, all of St. Lawrence County, Schneiderman said.

One of the out-of-county suppliers allegedly concealed the heroin he delivered from New York City by stowing it in the lining of the trunk of a 2008 Cadillac CTS. Defendants Caleb and Omar Serrano, who are brothers, concealed the cocaine that they trafficked inside of a lint brush in the car they drove, and another defendant, who is handicapped, concealed the heroin that he was transporting within the seat of his wheelchair that was stowed in his car. Drugs in this second alleged conspiracy came from New York City and Syracuse and were allegedly sold in the Edwards, Pierrepont and Stockholm areas of St. Lawrence County, Schneiderman said.

The third and fourth indictments charge nine people, four of whom are also named in the first two indictments, as members of the conspiracy to distribute heroin. Those charged in the third indictment include the handicapped defendant, who is charged with redistributing heroin for resale in the county via this third alleged network. The fourth indictment includes charges against a fourth out-of-county supplier with distributing cocaine to Jason Burnette, among other counts, Schneiderman said.

“The mission of this investigation was to arrest and remove heroin dealers that prey on our communities and to disrupt the flow of illegal drugs to our county -- we have accomplished that,” St. Lawrence County Sheriff Kevin Wells said. “On behalf of our task force partners and the people of St. Lawrence County, I want to thank the Attorney General and his staff along with all of the involved law enforcement professionals that have worked this case and that will continue to move it forward.”
