SNOHOMISH COUNTY, Wash. -- Prisoners are getting cold case decks of cards in an effort to help solve homicides and missing persons’ cases at the Snohomish County Jail.

The decks of cars will be distributed to the prisoners on Wednesday.

The cards feature 52 unsolved homicides or missing persons’ cases, dating back to 1972.

Each card has a photo of the victim (if available), a brief description of the crime and a tip line to call with information.

The youngest person featured is a 13-year-old girl, Yee Lu, who was found murdered in her Stanwood home on July 1, 1983.

The oldest person featured is an 87-year-old man, Martin Williams, who died in a fire in his Marysville home on July 10, 1987. The fire was ruled an arson.

Detectives said the goal is to get tips and leads that will help detectives solve some outstanding cases and find answers for grieving families who have been waiting years, even decades

Cold case detectives were able to buy 5,000 decks of cards that will be distributed to local jails and prisons.

The sheriff’s office got the idea after an article appeared about a cold case in Florida being solved using the cold case cards. A Florida detective got the idea from the United States military, which issued decks of playing cards with photos of the most wanted terrorists in Iraq and Afghanistan.
