The final video, prosecutors said, depicted the defendant having oral sex with her daughter. Before introducing it into evidence, prosecutors had the girl's father -- the defendant's ex-husband -- identify the voices captured on tape. He wept uncontrollably after identifying the voices as his daughter's and his ex-wife's and left the courtroom before the tape was played for the jury.
As the tape played -- its audio track filling the courtroom -- the defendant clapped her hands over her ears and wept.
The judge ordered the video stopped part way through, then had prosecutors skip to the end.
"This goes on for quite a while," the judge explained.
James Moir, the defendant's lawyer, earlier implored the jury to focus on whether prosecutors prove every element of each of the charges beyond a reasonable doubt.
"The issue is not whether (she) is morally depraved," Moir said. He acknowledged that the allegations are "shocking, reprehensible and despicable."
Kevin Watson, of Ontario, Canada, testified he spent Memorial Day weekend of 2012 with the mother and daughter in a motel room in Niagara Falls, Ontario. He said he met the girl online and that they had sexually-explicit Skype sessions before the rendezvous about three weeks after the girl's 14th birthday.
Watson said the defendant told him it was her daughter's first time having intercourse, and videotaped that and other sexual encounters during the weekend.
Brandon Ore, of Lebanon, testified he met the mother and daughter after responding to a personals ad placed by "two girls, 18 and 33, looking to party." He ultimately moved in with them in July 2012, and said it was weeks later that he learned they were mother and daughter, and that the girl was 14.
He moved out two months later and turned himself in to police, triggering the lawyer's arrest.
"The partying was out of control, the sex was out of control and she was charging high rent," Ore said, when asked why he left.
The lawyer was a member of, and had advocated for, the Alliance Defending Freedom -- an anti-gay Christian group.
