The man who robbed the Berkshire Bank location on Elm Street in Pittsfield has been sent to prison.

According to the Berkshire County District Attorney's Office, 36-year-old Christopher Rock from Lee pleaded guilty to multiple charges when he appeared in Berkshire Superior Court Thursday afternoon. Rock admitted to robbing the bank on Sept. 17, taking off with $2,000 and plead guilty to one charge each of unarmed robbery, larceny over $1,200 and possession of heroin.

After the robbery, a K-9 track was conducted by the Pittsfield Police, which resulted in additional evidence being located. Once the trail of evidence went cold -- somewhere around Superior Street -- a local cab driver had informed the PPD that he picked somebody up from that area and dropped him off at Madison Avenue and Seymour Street. The additional information lead police to arrest Rock at a residence in the area.

Rock was to four to five years in prison by Judge John Agostini. He will serve his time at the Massachusetts Correctional Institution at Cedar Junction.
