Whitney Middle School science teacher and former Big Brothers Big Sisters volunteer John Gisler, from Tulsa, Oklahoma, is facing a multitude of charges including forcible sodomy, second degree rape, and lewd molestation.
The accuser, 17, told the police that Gisler made him watch porn with him at the time of the molestations when he was just 14 years old, and Gisler was his Big Brother.
Additional charges may be pending after a police affidavit this week confirmed that child pornography was found on the man's computer.
