Winchester lawyer Paul H. Thomson, a former commonwealth’s attorney, pleaded guilty Monday to five criminal charges, most involving efforts to hide his relationship with a man who supplied him with cocaine.
Thomson, 56, signed a plea deal Sunday that calls for three years in prison and a $5,000 restitution payment, apparently a client’s fee refund. A fine is to be determined by the judge at sentencing.
The criminal case against Thomson was marked by sporadic sparring between defense lawyer John Flannery and federal prosecutors.
