A woman who filmed child porn videos to please her husband has been sentenced to 30 years in jail.

Anngela Boyle took photos and video of four children aged between 12 months and 9 to send to her husband, Colin Boyle.

The crimes took place at her home in Michigan, US.

She also admitted to abusing a 1-year-girl and a 3-year-old boy at least four times, along with her husband who has since been jailed for 60 years for the crimes.

Investigators described it as the "worst case" they had seen in two decades and said even seasoned officers were shocked by what they had discovered.

"This type of investigation will always rock a community to its core, and the gravity of the crime and the helplessness of the victims impacts even seasoned investigators," Lake Orion Police Chief Jerry Narsh said, quoted by the Detroit Free Press.

An investigation began after police found the husband, a known sex offender, was watching porn at home. They raided the house and found a camera with footage of a naked 1-year-old girl.

"[The wife] explained to law enforcement that child pornography is the only thing that sexually excited Colin Matthew Boyle," an FBI agent allegedly wrote in an affidavit quoted by Fox News.
