Uh oh, Miss Leyrer, you're in big trouble!

This 54-year-old Mount Morris, Michigan high school teacher - very harmless looking with her 54-year-old high school teacher haircut - has actually been operating as a mule for jail inmates, bringing them large quantities of drugs, some cash, and cell phones for the purpose of phone sex.

Yes, specifically, she was having sexy time on the phones with the inmates. She made over 350 calls to inmates in December alone.

Leryrer was ostensibly visiting the prison in the capacity of a "jail educator." So she was acting like she was doing good things, meanwhile she's sneaking her pupils enough fentanyl to kill a thousand elephants.

Here's what she's charged with:

• Delivery/ Manufacture of a Controlled Substance - a 20 year felony
• Bringing contraband into a facility - a 5 year felony
• Bringing a cell phone into a facility - a 5 year felony

Can you imagine volume of the chatter rising from the small town of Mount Morris, Michigan (population 3,000) right now...
