A former teacher in the Cooperstown School District has pleaded guilty to three counts of sexual exploitation of a child.

41-year old Justin Hobbie of Springfield Center was a gym and health teacher in Cooperstown until his arrest in December 2018.

The U.S.Attorney's Office say Hobbie admitted that from 2015 to 2018, he persuaded and coerced three girls under the age of 16 to engage in sexually explicit acts and send him sexually explicit photos.

Authorities say the acts and images were recorded by Hobbie so that he could look at them again

Hobbie faces at least 15 years in prison on each count, with a maximum penalty of 30 years in prison on each count when he's sentenced in December.

Hobbie will also be required to register as a sex offender.
