CONCORD - Jurors in the child pornography trial of Manchester attorney Lisa Biron in U.S. District Court saw videos that Biron is accused of making in which a 14-year-old girl is shown having sex with two different men.

In his opening argument, U.S. Attorney John Kacavas said Biron was a pot pusher, pornography producer and predator who considered the teen "an object, a thing."

Biron, 43, is accused of taking the girl to Canada, giving her alcohol and marijuana, and videotaping her as she had sex with a Canadian man she had met online.

Biron is also charged with making more videos, on a cellphone, of the girl having sex with another male in New Hampshire.

Defense attorney James Moir cautioned jurors that they were going to see graphic videos and said the issue here is not whether Lisa Biron is morally depraved.

He said the jury's verdicts must be based "on one thing and one thing only. Has the government proved each and every element beyond a reasonable doubt?"

During the morning session, the witnesses were two young men who testified they had sex with the 14-year-old and with Biron and that they were videotaped during their sexual activities with the teen.

The teenager will be one of the witnesses in what Judge Paul Barbadoro said he expected would be a two-day trial.
