Prisoners, at least in the United States, are forbidden from transfering money to other prisoners for any reason at all. So jrv's right--it ain't the other prisoners they're worried about.
This isn't even the weirdest case of bizarre lottery winners. The son of Tony Accardo--aka Joe Batters, the greatest mafia godfather of the 20th century--won the Illinois State lottery back in the 1980s. I don't think it's weird that he won, but it's weird that he was even playing. "Hey, you never know... Someday I could be even more of a millionaire."
It turns out that Accardo was one of them bootstraps fellers. He gave his kids everything but, like Vito Corleone, wanted them to go legit on their own merit. His grandson, Eric Kumerow, actually wound up a first round draft pick in the NFL, but didn't do much. I knew him vaguely a few years ago, and he was running a small (and somewhat struggling) landscaping business.
Think about that: your grandad's the most power mobster in the country for 40+ years, your dad wins the lottery, and you're planting shrubs after blowing out your knee playing professional football. Thank God I had low expectations in life.
