NORTH ADAMS — The Berkshire County Drug Task Force raided a West Main Street apartment Tuesday night, reportedly turning up crack cocaine and heroin.

After watching the property as part of a three-month investigation, police executed a search warrant and located Tyler Sumner, 23, who was allegedly in possession of $314 in cash, 23 bags of heroin and 8 grams of crack cocaine.

If sold on the street, the heroin is estimated by police to be worth $160 to $230, while the crack cocaine would bring in about $800.

Prosecutors argued that Sumner has engaged in "consistent criminal activity for years," referring to his multiple prior drug convictions.

Sumner's attorney, Glenn Keiderling, briefly questioned if police had substantiated the reliability of confidential informants referenced in the report and indicated he would explore whether the initial search warrant was valid.Sumner pleaded not guilty Wednesday in Northern Berkshire District Court to single counts of class A drug possession, subsequent offense, and class B drug possession, subsequent offense.

Judge Paul Vrabel set bail at $3,500 cash or $35,000 surety.

He is scheduled to appear in court June 22 for a pretrial hearing.
