Police say the urn was stolen from Diane Bozzi's van Tuesday morning in Rochester by someone targeting unlocked cars.
Diane Bozzi says the urn was in a bag that she was planning to take to her bingo game later in the day.
She and her mother loved playing bingo together. Before her mother died in 2002, Bozzi promised her she would take some of her ashes with her to play. Her mother agreed, saying she would bring Bozzi luck.
