Men who picked up Yellowstone bison: 'We didn't have the heart to leave it'

A Canadian man and his son loaded a Yellowstone bison calf into their vehicle because they thought it was an abandoned newborn, they said in an interview

A Canadian man and his son loaded a Yellowstone national park bison calf into their vehicle last month because they thought it was an abandoned newborn that would die without their help, the men said in their first interview since park officials had to euthanize the animal.

The calf was killed because it couldn't be reunited with its herd after being handled by Shamash Kassam of Quebec, Canada, and his son, Shakeel Kassam, on 9 May, park officials said.
