Authorities are investigating after a Boy Scout hike in the Arizona desert ended in tragedy with the death of a 16-year-old boy, according to reports.

Pinal County sheriff's officials say the troop had water but ran out when they got to the top of Picacho Peak April 27 and the boy began to exhibit signs of extreme dehydration on the way down.

A park ranger who arrived along with members of the Avra Fire Department tried to resuscitate the boy but couldn’t, KGUN-TV reported Thursday.

It’s unclear if the lack of water led to the boy’s death during the hike in Pichaco Peak State Park between Phoenix and Tucson, the Associated Press reported.
