TROY, New York (CNN) -- While inmates in jails across New York pass the time by playing card games -- poker, gin rummy and solitaire -- they may also be helping crack cold cases.
Thousands of decks of cards featuring cold cases have been distributed in New York jails.
The idea is simple: Each of the 52 playing cards contains information about a murder, a missing person or another unsolved crime.
Inmates know information law enforcement agents don't, and as corrections officers can attest, inmates love to talk as long as it's not about their own crimes.
