The man who sold Aaron Hernandez's jail-house letter to Sportsworld's Phil Castinetti -- who then received $18,000 for it from TMZ, which posted the letter on its Web site -- says he's upset with "the way it got out" and that he's been threatened by Hernandez's friends for making the letter public.
“I got people calling me and saying I better watch out,” said the man, who identified himself merely as "Karl" to the Boston Globe. “I regret how it turned out. I was kind of hoping more positive would come out of it.”
He also said the price he received from Castinetti for the letter was "pennies" compared to the $18,000 that TMZ paid.
“I don’t like the way it got out,” he said. “I wrote [Hernandez] last night because I don’t want him to think it was all about money.”
Hernandez had asked Karl not to put the letter on "social media".
