Although Walters used an assumed name, the Marshals Service said he "had boasted to people that he was a fugitive from San Diego and wanted by the US Marshals Service".
Walters allegedly bought chemicals to make methamphetamines from undercover Drug Enforcement Administration agents in 1988. An associate handed over the finished meth to a local dealer to hold. The dealer passed them on to yet another man.
When Walters wanted the drugs back, he kidnapped the dealer who had been holding the meth, his friend and the friend's girlfriend, offering the hostages in exchange for the return of the drugs.
Two hostages were released but the girlfriend died because she had been gagged with a chemical-soaked rag.
Walter's brother Martin was convicted in the kidnapping and murder and is serving 25 years to life in prison.
"Thanks to hard work ... we were able to bring Walters in to face the consequences ... ," said David Harlow, assistant director of the Marshals Service's Investigative Operations Division.
