Amy Lynn DeLaCruz, 41, was found dead inside the cab of a 2023 Freightliner semi-truck in a trucking company lot in the 1000 block of North Service Road in Foristell, Missouri. St. Charles County officers arrived about 3:15 a.m. on February 22, 2024, and determined she died of a gunshot wound to the head. Detectives opened the case as a homicide investigation.

Investigators identified 28-year-old Clyde E. Young of Godfrey, Illinois, as the registered operator of the truck. Young contacted dispatchers shortly before 4:40 a.m., acknowledged a romantic relationship with DeLaCruz, and told police an argument the previous night escalated and he retrieved a shotgun and shot her. He later moved away from the initial scene; a pursuit ended nearly 50 miles away in West Alton, Missouri, at a Phillips 66 on Highway 67. Young refused to exit his vehicle during a standoff, retrieved a firearm, and shots were fired. Young sustained a fatal gunshot wound that preliminary investigation suggested was self-inflicted. Prosecutors filed charges of first-degree murder and armed criminal action but the criminal case was closed after his death.

Are there details about the timeline or any witnesses in Foristell or along Highway 67 that could help fill gaps in the morning’s events?
