Though it was never proven in court, Metheny said in a jailhouse confession that he butchered the bodies of Magaziner and Spicer and sold the meat in a roadside stand, calling it his 'special meat'.
'I had real roast beef and pork sandwiches and why not they were very good,' he wrote. 'The human body tastes was very similar to pork. If you mix it together no one can tell the difference.'
After he pleaded guilty to murdering Spicer and Magaziner, Metheny begged a jury for the death penalty.
'The words `I'm sorry' will never come out, for they would be a lie,' he said in court.
'I am more than willing to give up my life for what I have done, to have God judge me and send [me] to hell for eternity.'
The twisted killer concluded his jailhouse confession with a warning for hungry travelers on unfamiliar roads.
'So the next time you're riding down the road and you happen to see an open pit beef stand that you've never seen before, make sure you think about this story before you take a bite of that sandwich,' he wrote.
'Sometimes you never know who you may be eating. Ha! Ha!'
