(MTN NEWS-HELENA) A second unidentified woman is suing the city of Helena and Lewis and Clark County, over claims she was sexually abused by a Helena police officer. The lawsuit says the woman worked as a confidential informant for the Missouri River Drug Task Force when former HPD officer Matt Thompson allegedly forced her into sexual acts.

According to the suit, Thompson first met the accuser in 2008, while he was a school resource officer at Capital High School and she was a student. In 2012, after Thompson started working for the drug task force, the woman claims he recruited her as an informant.

The suit claims Thompson gave the accuser alcohol, knowing she was underage, and forced her into sex two times.

The woman’s lawyers say Thompson threatened her with jail time if she didn’t cooperate with him. After Thompson left HPD more than three years ago, she says he ordered her not to speak to investigators from the city or county.

“My client was vulnerable to begin with, and Mr. Thompson would have had knowledge of her vulnerabilities,” said Tim McKeon, one of the lawyers representing the woman. “These events have significantly caused her harm and damage.”

McKeon, of Helena’s McKeon Doud Law Firm, says the city and county were negligent in hiring Thompson and in supervising him.

The latest lawsuit comes just four months after another woman accused Thompson of sexually abusing her while she worked as an informant. That case is still open, and there have been no hearings yet.

McKeon Doud is representing both women, along with the Zalkin Law Firm of San Diego, California.
