Zamora is serving a life sentence at Western State Hospital for killing six people during a shooting spree in 2008. But a Sedro-Woolley man who formed a relationship with Zamora is now selling personal items from the killer to various websites.
"I've sold to people to sell on their websites," said the merchant, who asked to remain anonymous. "I guess you could say I'm the go-to guy for these."
Some of the items include a finger print chart that can go for $100-$150, or hand prints that can sell for as much as $45 on the sites.
The merchant also sells sheets of paper that show an outline of Zamora's hand, along with a signature and a stamp of his fingerprint.
But the families of some of his victims have voiced their displeasure with the business, saying they're offended anyone could make money off of a massacre.
The merchant says he doesn't try to rub it in the victims' faces.
"That's not what I'm trying to do at all. I just know that true crime is a big market right now and it's booming," he said.
Zamora never sees a penny for any of these dealings. Washington law requires any profits made from re-telling or re-enacting a crime go to a state-managed crime-victims fund. But it does not prohibit prisoners from selling personal items.
The merchant KOMO News spoke to says he's not idolizing serial killers at all.
"I don't condone what they do," he said. "But at the same time, there's a market in it. It may be tasteless but it's reality."
A man in Massachusetts who bought one of Zamora's hand tracings says he wants to make them a part of a serial killer museum.
