Last Jaguar in the US now dead

A sad story about what was probably an attempt to track the last known jaguar so that it could be studied (that's me being hopeful) or kept away from areas that are inhabited by people (and that's me being more cynical).

Need I even go into it that humans are encroaching on wildlife habitats, causing not only endangerment and dangerous animal/human encounters, but also retaliations by humans in this manner? Doing bad under the assumption that it is really good?
