This is another one of those cases where I shouldn't have read the article:
"Different videos captured that the incident allegedly showed Matsoukas moving his iPad to various spots and positions. At one point, investigators said he began to rub his chest and masturbate. He then bent over and pulled the dog’s leash, getting the dog to lick his anus while he continued,” WTAJ reported."
"The shocking footage reportedly showed the professor wearing nothing but a ski mask, boots with socks, and a wristwatch, and carrying a North Face backpack.
Matsoukas reportedly could be seen masturbating near a women’s public restroom, before “engaging in a sexual act with the dog,” according to the affidavit.
The man also allegedly tried to record his antics with the collie using a silver iPad."
