Sarah Tonkin, 37, died when a tow hitch assembly became dislodged from an Isuzu truck and struck her vehicle head-on, causing severe head injuries. The hitch pin securing the tow hitch was not properly installed during truck modifications at Brenmark Transport Equipment. Despite thorough investigation, it remained unclear whether improper installation or theft during vehicle storage caused the failure. The coroner recommended industry regulators review tow hitch installation procedures and consider mandatory tethering of hitch pins to prevent similar incidents. This case highlights the importance of rigorous quality control during vehicle modifications and inspection protocols.
