The Connecticut Division of Criminal Justice hopes a new stack of "cold case" playing cards will spur inmates to speak.

The cards, announced Tuesday, feature the names, faces and other information about old homicide cases, as well as contact information so inmates can give authorities information about the cases.

The September 1996 murder of a Stamford woman and her baby boy is one cold case that is being featured in the new deck of 52 cards. Police say 18-year-old Rhonda Johnson and her 6-month old son, Co'ran, were found shot dead inside a car along Grenhart Road.

"It is frustrating. We're very, very close with this we just need a little more information to get us over the top," says Stamford Police Department Sgt. Paul Guzda. "And hopefully this will do it," he said referring to the playing cards.

Authorities say the cards will only be available to inmates. This is the state's third edition of cold case playing cards.
