A jury convicted 25-year-old Joseph Nicholson on Thursday of charges including involuntary deviate sexual intercourse and statutory sexual assault for his contact with two 15-year-old girls and a 16-year-old at Downingtown West High School.
Nicholson was charged last year. Administrators say he told them girls threw themselves at him when they confronted him. He resigned from his job soon after.
Defense attorney David Clark says Nicholson is disappointed with the jury's verdict. Clark says he will discuss an appeal with his client.
A sentencing date has not been set.
