A 49-year-old Colorado man died at a Boise hospital Saturday night, after suffering injuries in a motorcycle crash in Elmore County, according to the Elmore County Sheriff's Office.
Jeffrey D. Jackson of Grand Junction was identified by the sheriff's office as the crash victim.
The crash occurred at about 7:42 p.m. Saturday in the eastbound lanes of Interstate 84, near milepost 92.2.
Witnesses told investigators that Jackson was passing vehicles in the left lane when he lost control and veered off into the median. He was unable to steer the 2005 Honda back to the highway, and it overturned. Jackson, who was not wearing a helmet, was thrown from the motorcycle.
Paramedics transported Jackson to Saint Alphonsus Regional Medical Center in Boise, where he died from his injuries. The sheriff's office says a preliminary investigation indicates that alcohol was not a factor in the crash.
