A Florida father says he is on a mission to shut down a website that sells memorabilia from convicted murderers.

Roy Brown and his wife Silvia placed a rose near their daughter Amanda's picture earlier this week, during a Missing Children's Day ceremony at the capitol.

Amanda disappeared in 1998.

Her body has never been found.

But, Willie Crain was sent to death row for her murder.

Recently, a letter from Crain showed up on a website, along with art work and personal items from other killers looking to cash in.

Roy Brown says it needs to be stopped.

Roy Brown, Father of Missing Child: "We pay for this guy to breathe. It's bad enough that he gets to see his daughter, I'll never get to see mine. Now he's making money off my daughter! There's something wrong with this."

Florida's law says killers can not profit from their crime..

Roy Brown met with an aide to the governor.

The Attorney General's Office says it also wants to know more about the website.Dad Crusades Against Murderer's Momento Auction Site
