A female elephant named Sambo, trained to carry tourists at Angkor, collapsed and died on April 22, 2016 near Bakheng Mountain in the archaeological park.

The 40-to-45-year-old elephant had worked for the Angkor Elephant Company since 2001, according to manager Oan Kiri.

Sambo died after taking two trips from Bayon Temple to Bakheng, having walked about 40 minutes. Veterinarian concluded that she died of heart attack due to high temperatures and lack of wind. Siem Reap recorded a high of 40 degrees Celsius on Friday.

The question is why the owner of Sambo didn't stop the tour? When it's hot outside animals and humans should rest!!! In this role, he is the responsible of the death of this elephant.
