Masako Yamada Kenley, 53, was reported missing from her Sandy, Utah, home after failing to meet coworkers for dinner on July 2, 2021. Her husband reported her missing July 3, and her vehicle was found in a Costco parking lot. On July 4 her body was located concealed in a heavily wooded area along the Jordan River. Investigators classified the death a homicide; an autopsy determined she suffered two gunshot wounds, one to the neck and one to the chest that struck her heart, plus four stab wounds to the neck, one of which severed a carotid artery. The cause of death was a combination of those injuries.

Cell phone data and surveillance footage placed Kenley with 75-year-old William Richard O'Reilly on the afternoon of July 2. O'Reilly, a former coworker from the U.S. Post Office, was described by acquaintances as having become obsessed with Kenley, allegedly following her, making threats, and placing a tracking device on a vehicle he bought for her. He was arrested July 5, 2021, after an apparent suicide attempt at a local hospital and admitted to investigators that he turned off Kenley’s phone and hid her purse and a shoe in his vehicle; he was charged with aggravated murder, obstruction of justice, and desecration of a human body.

Did anyone who knew Masako or worked with her notice signs of trouble in the months before July 2021?
