The latest installment in ‘why humans are the worst.’

Sadly, murder has become a part of everyday life for Salvadorans. The tiny country?—?which is home to just over 6 million people?—?has one of the highest homicide rates in the world.

But when criminals killed an innocent animal in a zoo last week, the country lashed out in rage.

“They kill us like flies, but this tops it all,” a street vendor in the country’s capital tells the Associated Press. “They killed an animal that only entertained us.”

Unknown assailants appear to have broken into El Salvador’s National Zoo on Tuesday, AP reports, and zoo staff noticed two days later that Gustavito, a 15-year-old hippo, had bruises and puncture wounds all over his body.

Zoo director Vladan Henriquez said at a press conference that it looked like Gustavito was beaten with rocks, metal bars and possibly even an ice pick.

It took zoo staff two days to notice Gustavito’s injuries because he stayed in his pool after the attack. The hippo died on Sunday.

El Salvador is notorious for its violent street gangs, but so far there’s no indication that this attack is gang related.

The zoo buried Gustavito immediately so that people would remember the hippo alive and happy, eating fruit and swimming in his tank.
