A New Hampshire lawyer known for her work with an anti-gay Christian legal group was found guilty Thursday of several sex charges after she drove a 14-year-old girl to Canada and forced her have sex on camera last spring.

The FBI indicted Lisa Biron, 43, on charges of transportation of a minor with intent to commit criminal sexual activity, sexual exploitation of children and possession of child pornography.

The jury took little more than a lunch hour to convict the New Hampshire woman, the Union Leader newspaper reported.

Evidence presented at the trial included cellphone videos of the 14-year-old having sex with two men and with Biron at different times and places.

The men included Kevin Watson, 20, who testified the girl was brought to a Niagara Falls, Ont., hotel room for him to have sex with late last spring, according to local reports.

Biron has worked with the Alliance Defending Freedom, which describes itself on its website as a "legal ministry" dedicated to spreading the gospel "by transforming the legal system and advocating for religious liberty, the sanctity of life and marriage and family."

Biron was previously arrested in October 2012 for possession of child pornography. She was in court for a hearing on those charges a month later when she was taken into custody for the second time.

The sentencing hearing for Biron is set for April 22. A U.S. attorney told the Union Leader she faces a minimum sentence of 25 years in prison.
