EVANSVILLE, Ind. -- An inmate serving life in prison for molesting and killing a child has had the victim's name tattooed across his forehead.

Anthony Ray Stockelman, 39, admitted molesting, kidnapping and killing 10-year-old Indiana girl Katie Collman. Katie was missing for five days before her body was found last year in a creek.

A photo of what is identified as Stockelman's forehead and eyes appeared online on a blog that focuses on news reports about crimes against children and women. The tattoo covers nearly his entire forehead, has "KATIE'S" in large letters and "REVENGE" below in smaller letters.

Indiana prison officials now think they know who tattooed the words across the killer's forehead.

The blogger said she received the photograph in an e-mail last Saturday. She said the e-mail also claimed a distant relative of Katie's who also is at the prison had given Stockelman the tattoo. She said it was not clear how many others were involved in the assault.

Prison officials would not confirm the account of how Stockelman was tattooed, but said an inmate has been identified as a suspect.

They've also fired two guards suspected of giving a photo of the tattoo to a crime blog.

Prison spokesman Rich Larsen said two guards were fired for making "unauthorized copies of an evidence photo."

Stockelman was separated from the general prison population after authorities discovered the tattoo last weekend.

Katie's father John Neace said he heard about it from friends, and figured other prisoners are responsible. He said he thinks the tattoo was a statement from the other inmates.
