On a hike through the bush, he came across a young bull elephant standing with one leg raised in the air
The elephant seemed distressed, so Dave approached it very carefully
He got down on one knee, inspected the elephant's foot, and found a large piece of wood deeply embedded in it
As carefully and as gently as he could, Dave worked the wood out with his knife, after which the elephant gingerly put down its foot.
The elephant turned to face the man and with a rather curious look on its face, stared at him for several tense moments
Dave stood frozen, thinking of nothing else but being trampled
Eventually the elephant trumpeted loudly, turned and walked away.
Dave never forgot that elephant or the events of that day.
Twenty years later, Dave was walking through the Chicago Zoo with his teenage son
As they approached the elephant enclosure, one of the creatures turned and walked over to near where Dave and his son Jake were standing
The large bull elephant stared at Dave, lifted its front foot off the ground, then put it down
The elephant did that several times then trumpeted loudly, all the while staring at the man.
Remembering the encounter in 1993, Dave could not help wondering if this was the same elephant
Dave summoned up his courage, climbed over the railing and made his way into the enclosure
He walked right up to the elephant and stared back in wonder.
The elephant trumpeted again, wrapped its trunk around one of Dave's legs and slammed him against the railing, killing him instantly.
Probably wasn't the same elephant.
