Marius Els Killed By His Pet Hippo Humphrey, South Africa

Mr Els, who was married, kept 20 different species of exotic animals, including giraffe and rhino, on his farm near Klerksdorp in South Africa's north west. But he developed a special fondness for Humphrey, whom he bought aged just five months and for whom he even built a special lake.
Humphrey was aged six and weighed more than a metric tonne when he attacked Mr Els. While Mr Els appeared to revel in his status as the man who had tamed a hippo, he did recognize his pet's power and danger.
'If he decides to get me off his back, then he throws me over like a horse', Mr Els told an interviewer before his death, adding: 'My friends won't even go near him.'
