Death

The sheriff's office has thus far declined to detail the nature of the medical emergency suffered by Griffiths.

The man was taken to Memorial Hospital of Sweetwater County, where he was pronounced dead.

The driver overcorrected, causing the combination unit to roll onto the driver's side.

Further details were not immediately released.

Kelley had been traveling on foot, according to the sheriff's office.

Other students had reported to school administrators that Ritthaler was last seen walking toward the Coffee Cup.

Meade County Sheriff Ron Merwin said he couldn't yet share details on how the girl died.

The Toyota again left the pavement and entered the median, where it rolled several times before coming to a rest in the westbound lanes.

Ritthaler was last seen shortly after 12:30 p.m. Thursday getting into a dark-colored vehicle at the Coffee Cup in Moorcroft.

The driver of the pickup tried to stop but was unable to avoid a broadside collision with the driver's side of the Pontiac.
