Minnesota Bureau of Criminal Apprehension

Allegations of a sexual assault involving an infant led to the child pornography charges.

The 38-year-old Rice County woman was accused of sending nude photos of herself to at least 5 students in the Northfield Public Schools.

The charges in the case stem from a cyber tip originating with Snapchat.

The Minnesota Bureau of Criminal Apprehension issued the alert for 31-year-old Brian Spencer.

The charges include use of a minor in a sexual performance/pornographic work.

The investigation started when the staff and the Twin Cities library viewed to the manifesto.

He was accused of sexually assaulting the juvenile while keeping her hidden from authorities in a tent that he had set up behind a friend's home.

Police say they are not looking for any suspects.

A news release says the Minnesota Bureau of Criminal Apprehension is assisting with the investigation.

The Walker Police Department says the man was charging at an officer with a knife.
