“The smartphone recorded the moment he slipped and fell into the pool and her efforts to rescue him,” the report said. There was no cellphone service in the area, so Sable reportedly went back to a nearby museum for help.

Several hours later, Colin’s body was found floating on the water, though officials were unable to recover it after a thunderstorm forced them to call off the operation. When they returned the following day, there was nothing left of the young man, except for a wallet and flip flops.

Veress wrote in his incident report that on the day Colin met his tragic end, the waters had been especially acidic. “In a very short order, there was a significant amount of dissolving,” he wrote.
