When Ray is sitting at his desk holding the picture of the dog, he is staring at the back of the picture. It cuts to a view of the back of the picture where the words "Miss You" "Love Damien" and the address for the US Marshal's Office are very clearly written in thick black ink. However, when he turns the picture around, there is nothing written on the back of the picture. Also, when he puts the picture face down on the desk there is nothing written on the back.
