POCATELLO, Idaho (AP) — Idaho authorities have asked the public for help finding money and handwritten cards stolen from a funeral at The Church of Jesus Christ of Latter-day Saints building in the city of Preston.

A viewing was held March 6 and funeral was held March 7 for Jeff Green, who died at age 55 in late February following a six-year battle with cancer, the Idaho State Journal reported Thursday.

Someone during the viewing and funeral stole a substantial amount of money donated to the family and dozens of handwritten cards, his son Hayden Green, said. The cards were inscribed with memories the family planned to share with Jeff Green's 4-year-old daughter.

The Preston Police Department posted on Facebook asking anyone who noticed or saw anything to contact the department. Anyone who donated should also contact authorities to better track the money and how much is missing.

“My dad’s wife Tiffany of about eight years was never able to have children, but they had an oops baby four years ago,” Green said. “You have all these people who wrote these notes for my dad at the funeral of their favorite memory of him for Sawyer so that over the years Tiffany could give her these cards and share a piece of my dad with her."

He added: “Whoever took this wicker basket full of cards didn’t just take money from us, they literally robbed a 4-year-old and grieving wife of my Dad’s memory. That’s just so frustrating.”

Police Chief Dan McCammon told the Journal on Tuesday that the department has received leads, but that investigators do not know where the money went.

“Investigating something like this is extremely hard,” McCammon said. “There is no video and everybody who was there is a witness or potential suspect. We are trying to find any evidence to lead us in the right direction and we will follow any lead that we can get.”
