Deputies said they began investigating DesJareins earlier this month when someone found a computer thumb drive in his driveway.
Officials said on it were photos and videos of children being forced to have sex with adults.
DesJareins is charged with five counts of second degree sexual exploitation of a minor and five counts of third degree sexual exploitation of a minor.
Investigators said additional charges against DesJareins are expected.
DesJareins is being held in the Cumberland County Detention Center under a $100,000 bond. He is due in court on Monday.
