Overview
- Dolly Regene Young, 47, was thrown from a Matterhorn Bobsled car in 1984 and was killed when struck by an oncoming sled estimated at about 20 mph.
- Investigators said her seatbelt was unfastened but did not establish whether it was deliberately undone or malfunctioned.
- Disneyland spokesman Bob Roth said no mechanical breakdown was found and that Young’s companions realized her absence only when the ride ended.
- Contemporary reports indicate the ride was halted within roughly 30 seconds, closed immediately, and was understood to have reopened the next day.
- The retrospective also notes a prior fatality on the ride in 1964 involving 15-year-old Mark Maples, with witnesses suggesting he may have unbuckled his belt on the single-file attraction.
