How are fatal crashes like this investigated?
Officers typically document the scene, interview witnesses, inspect the vehicles involved, and review any available video or data before determining a cause.

Timelines vary, but a full report can take several weeks to a few months depending on the complexity of the crash and whether toxicology or mechanical findings are involved.
