STUART — A Jensen Beach man who blamed his cat for the crime of downloading images of child pornography onto his home computer was ordered Tuesday to serve more than a dozen years in prison after pleading no contest to 25 felony charges.

In August 2009, authorities arrested Keith Griffin, 49, and initially charged him with 10 counts of possession of child pornography. Prosecutors later filed 90 more possession of child pornography charges, with each count representing at least 10 images.

Records show Martin County Sheriff’s Office investigators found the images on Griffin’s computer. His explanation was that his cat would jump on his keyboard while he was away, sheriff’s officials said. He said when he returned later, he discovered the material had been downloaded, investigators noted.

After court, Denton characterized Griffin’s “the cat did it” defense as “bizarre.”

Fucking cats man, one minute you’re getting up to grab a cup of coffee and the next you have a hard drive full of child pornography. I’ve seen this happen a million times. Cat’s love kiddy porn, theyre fucking perverts like that. That’s why you got to lock that keyboard when you get up otherwise you could end up in jail while your stupid cat gets to watch all the free porn it wants back at home.
