PITTSFIELD -- A Berkshire Superior Court jury has found a 72-year-old North Dartmouth man guilty of six out of seven charges in a sexual abuse case involving a woman with developmental disabilities.

Richard St. Louis slowly shook his head back and forth as the guilty verdicts were read in court on Tuesday morning.

The seven-woman and five-man jury spent about seven hours deliberating on Monday and had signaled late in the day that they were "stuck" on verdicts for five of the charges, but the judge urged them to press on. After an hour deliberating on Tuesday morning, the jury came back with its verdicts.

St. Louis was found guilty of four counts of indecent assault and battery on a person with intellectual disabilities and single counts of indecent exposure and accosting a person of the opposite sex. He was found not guilty of a single count of indecent assault and battery. He is expected for sentencing later on Tuesday.

He was accused of inappropriate sexual contact with a 24-year-old woman who prosecutors said has the problem-solving skills of a 4-year-old. The abuse took place on various dates between Jan. 1, 2008, and Sept. 16, 2011, in Hancock, where St. Louis would go to hunt, according to Assistant Berkshire District Attorney Marianne Shelvey.

The victim took the stand against St. Louis during the four day trial.

St. Louis also took the stand and denied he had any inappropriate contact with the woman. His attorney, Jack M. Atwood, said the woman had been manipulated by her mother into lying.

Shelvey asked that the sentencing be postponed until this afternoon in order for her to meet with the woman's mother to get input on a sentencing recommendation.

Following the verdict, a tearful St. Louis was led away in handcuffs and is being held without bail until the sentencing hearing. He had previously been out on personal recognizance.

His family was emotionally distraught after the verdicts were read.
