From the good folk at The Anomalist:
"Argentina: Chupacabras Changes Diet Inexplicata.
"The location: Rosario, Argentina. The time: the early morning hours last Thursday. The crime: one of two dogs on a residential terrace is completely drained of blood with a single wound to the throat and no bloodstains around it. The other dog is unharmed. The question: has the chupacabras, or 'goat sucker,' changed its diet?"
