The Wyoming Highway Patrol says driver inattention, cell phone use or a possible medical condition could be contributing factors in a crash that left a 44-year-old man dead last week.
According to a recent report, Rocky Vaughan was driving a Nissan Frontier southbound Thursday afternoon on North Poplar Road when he ran a stop sign at the intersection of Events Drive.
Vaughan subsequently ran into the front driver side of a Casper solid waste vehicle. He was then ejected from his vehicle and suffered fatal injuries.
The driver of the solid waste truck suffered minor injuries.
