The Taichung District Prosecutors' Office says autopsies have confirmed that
four hikers killed in a rockfall died of traumatic shock caused by falling
rocks.

The statement comes after prosecutors and forensic examiners conducted the
autopsies after the victims' bodies were taken to a funeral home in Taichung.

The prosecutors' office has ruled that the four deaths were accidental, and
issued death certificates after the victims' families raised no objections to
the findings.

Prosecutors says they are continuing to investigate whether the accident
involved criminal negligence.

The victims were among a 16-member hiking group organized by the Republic of
China Primitive Life Education Association that traveled from Taipei on
Saturday to hike the Butterfly Valley Waterfall Trail in Taichung's Heping
District.

Authorities says rocks struck five members of the group on the trail, killing
four and leaving one with minor injuries.

Association Chairman Wu Swei-pi says the weather was clear when the group set
out and forecasts had shown no rain was expected in the area Saturday
afternoon and the they were struck by falling rocks while crossing a stream.

Wu says warnings or a temporary trail closure could have alerted hikers to
the danger.

The Taichung Branch of the Forestry and Nature Conservation Agency says the
trail remained open because rainfall associated with Tropical Storm Mekkhala
had not met the threshold for closure.
