Man sets up camera to catch ghost, films girlfriend's affair with his teenage son
According to The Telegraph website, the man forgot to turn off the camera one day and when he later reviewed the footage, he saw his son and the 28-year-old Tasmanian woman - who cannot be named for legal reasons - kissing and cuddling.
His girlfriend of 11 years initially denied the affair, but his son confessed that they had sex on multiple occasions.
The woman later pleaded guilty to sex with the minor and today was sentenced to at least six months in jail.
The court heard the illicit affair began last year. It was discovered in October, when the boy was moved to live with his grandparents.
Justice David Porter said the woman had known the minor since he was nine and was effectively his stepmother, although he had begun living with her only in 2012.
"You did that knowing full well it was unlawful," the judge said. "You have caused much disruption to this young man's life."
The woman was sentenced to a year in jail with a six months suspended sentence on condition of good behaviour.
Tasmania, the island state south of Australia's mainland, has the legal age of consent at 17 years old.
