A former Knox County Jail Guard convicted in 2014 of sexual assault against an inmate was sentenced to serve eight months in jail for violating his probation by assaulting another woman.

Adam Grierson, 29, of Union, pleaded guilty in August 2014 to a charge of gross sexual assault for having a coerced sexual relationship with a female inmate at the jail while he was employed as a corrections officer. He pleaded guilty to the charge and was sentenced to serve 15 months in prison, with all but 60 days suspended. He also was ordered to be on a period of probation for two years.

On Sept. 25, Grierson was arrested by Rockland police and charged with domestic violence assault and criminal mischief for forcibly pulling a woman out of a car and onto the ground during an argument.

On Oct. 30, Grierson admitted to the probation violation was sentenced to serve eight months in jail. On the domestic violence assault charge, he was sentenced to 364 days in jail, all suspended, and will be on probation for two years.

When police located Grierson in Rockland, he told them the fight started because he did not want to go home with the victim because she was "being mean," says the affidavit.

He admitted pulling her out of the vehicle and said he regretted doing so, but that it happened in the heat of the moment. He agreed with police that he did not have the right to do that, say court papers.

A civil lawsuit was filed in 2014 by the former inmate and sexual assault victim against Grierson, seeking $300,000 in damages.

In the complaint, the victim contended Grierson coerced her into having sex with him. The lawsuit also cited Knox County Sheriff Donna Dennison for failing to prevent the incidents.

The complaint filed against Grierson stated three sexual encounters occurred while the victim was incarcerated in 2012.

The victim told police she had sex with Grierson in exchange for cigarettes and provided names of three women she was housed with at the jail who could confirm her allegations. When interviewed, the witnesses gave details supporting the victim's statements, according to court documents.

The civil case was dismissed by the parties in September 2014. A federal judge found in favor of Knox County Jail employees, including Dennison, in the case.
