A 45-year-old B.C. woman has been sentenced to 10 years in prison for travelling to northern Virginia to have sex with two children in a U.S. Department of Homeland Security sting.

Theresa Louise Goddard was sentenced Friday in federal court in the U.S. She had pleaded guilty in October to attempting to coerce and entice two children into engaging in illegal sexual activity.

According to court documents, Goddard posted on a website that she wanted to start an "incest family."

Prosecutors say an undercover agent with Homeland Security Investigations responded to the postings and the two began communicating by email and then by Skype.

Authorities say the agent told Goddard he had two children, a 10-year-old girl and a nine-year-old boy.

Goddard, who worked at a lumber mill in Surrey at the time, made plans to travel from Vancouver to northern Virginia to meet the family.

She was arrested June 26 at Dulles International Airport in Washington, D.C.
