In March of 2023, a 58-year-old woman headed to a Seattle Mariners game with a man she had met at Costco two weeks prior. But after enjoying their date, even snapping a photo together in the stands, she went missing. When the following day brought strange text messages sent from her phone, and a report that her son had been abducted from his bed, investigators started to piece together a disturbing puzzle. This is the murder of Leticia Martinez-Cosman.
