Reports died down after the early '80s and didn't pick up again until recently. At the end of July 2019, a dead bull showed up on Silvies Valley Ranch in Central Oregon. Within 24 hours, ranch hands had discovered four more carcasses. The cattle's tongues and genitals had been surgically removed, and they had been completely drained of blood.

The events have certainly had no lack of media coverage, leading to a host of crazy conjectures ranging from Bigfoot to government corruption. The popular opinion, however, seems to be extraterrestrial activity – sneaky aliens coming down to Earth, mutilating livestock and creeping back to their UFOs, tote bags full of souvenir cow penises. Another widespread speculation is the involvement of Satanic cults.
Interestingly enough, according to local experts, this may be the most likely theory.
