Logan,UT : Holladay man killed in rollover crash near Garden City on June, Wednesday 28th 2017

The Utah Highway Patrol said a mechanical malfunction may have led to a rollover crash on U.S. Highway 89 in Garden City that claimed the life of one man and left another in serious but not life-threatening condition in a Salt Lake area hospital.

According to Lt. Lee Perry, 53-year-old Gary Gygi of Holladay was behind the wheel of a silver 1999 Dodge quad-cab truck pulling a utility dump trailer loaded with mulch.


Witnesses said as the truck approached Garden City, the trailer began to whip side-to-side and Gygi lost control of the vehicle. The truck went off the right side of the road, where it rolled.

Gygi, who was not wearing a seatbelt, was ejected from the vehicle. A medical helicopter landed at the scene of the crash and he was flown to the University of Utah Hospital in Salt Lake City.


His father-in-law, identified as 80-year-old Wilford Karl Diederich, also of Holladay, suffered a head injury and died at the scene of the crash.

Perry said the investigation is ongoing and will include a thorough inspection of the brakes on both the truck and trailer, as well as the hitch system.
