Poisoned zoo animals
An orangutan, a European bison, an elephant, three chimpanzees, three tapirs, and four camels have been murdered by poisoning at the Sao Paulo zoo. Some of the bodies show the presence of sodium fluoroacetate (CH2F-COON), used in powerful rat poisons that are outlawed in Brazil (and the U.S., as far as I have been able to determine, although it used to be used to kill ground squirrels in California.)
