I thought Snapchat deletes photos?

A Missouri mother is finding herself in hot water after a topless photo of her and her daughter circulated through the school district via Snapchat this past weekend, The St. Louis Post-Dispatch reports.

The 50-year-old mother has not been identified in order to protect her daughter, who is a minor.

The photo was shot by the girl's sister, police told the Post-Dispatch.

It was taken Nov. 14 in a hot tub at their Wentzville, Mo., home, and circulated through at least two high schools via Snapchat, the here-and-gone photo-sharing app. Although, if you screenshot the photos when you receive them, they are as permanent as any picture you save to your phone. 

St. Charles County Prosecutor Tim Lohmar sent Business Insider the official court document, which stated the woman is being charged withmisdemeanor child endangerment.

Lohmar told the Post-Dispatch that "it was clear that the woman and her daughter had knowingly posed for the photo. Both of them were covering their nipples, but their breasts were exposed."

Uh, I think they're doing Snapchat wrong.
