Larry James Chiasson, 68, was killed in Lafayette, Louisiana, on December 10, 2018. He was driving a truck when a passenger’s firearm was unintentionally discharged; Chiasson was struck, the vehicle crashed, and he died at the scene.

The passenger was identified as 18-year-old Dawson Mullen. An eyewitness said the truck had come from a sidewalk near a Shell Station and then crossed traffic before the crash. Mullen was arrested and charged with negligent homicide in connection with Chiasson’s death.

The sequence of the weapon’s discharge, the resulting impact on the driver, and the eyewitness account are central to understanding what happened that day. Does anyone have additional information about the events near the Shell Station or the moments before the discharge?
