In the winter of 1987, a 30-year-old mother named Kathy Jean Diamond was living in Las Vegas, Nevada. On February 7th, she was in the 4400 block of Boulder Highway when she informed her oldest son that she was heading to the store and would be back later. Kathy, who sometimes went by the surnames Canonico or Smith, left with a friend in a maroon and red 1982 Mercury Capri. She was dressed in a white jacket, blue jeans, and white sandals, and she carried a white purse. That night, her youngest son had a nosebleed and went to his older brother for help when he couldn't find his mother. The two boys then went back to sleep, but when they awoke for school the next morning, their mother had still not come home. Kathy Jean Diamond was never seen or heard from again.

Her boyfriend officially reported her missing to the Las Vegas Metropolitan Police Department on February 8, 1987. The investigation into her disappearance began, but clues were scarce. Three months later, in May, a significant piece of evidence surfaced. The 1982 Mercury Capri that Kathy was last seen in was discovered abandoned. The vehicle was located in a parking lot in the 4400 block of Jimmy Durante Drive, which was not far from her apartment. Authorities processed the car for any evidence that might lead them to Kathy's whereabouts, but their search yielded nothing conclusive. Despite this discovery, the trail grew cold, and the specific circumstances surrounding what happened to her after she left for the store remain unclear.

For decades, the disappearance of Kathy Jean Diamond has remained an unsolved case, leaving her family with unanswered questions. At the time she went missing, Kathy was described as a Caucasian female with brown hair and green eyes. She was 5'3' tall and weighed approximately 130 pounds. She had distinct facial features, including a mole under her right eye and a scar beneath her nose. The Las Vegas Metropolitan Police Department has kept her case open, classifying her as an endangered missing person. Over the years, little new information has emerged, and the identity of the friend she was with on that day has not been publicly detailed. The case is a long-standing mystery, a story of a mother who went out for a routine errand and vanished, leaving behind a life and a family still waiting for answers.
