When we lived in TX for 10 years there were Chupacabra sightings from time to time.
My Husband's grandmother swears they are in Puerto Rico (she used to, she's too ill now to pay much attention).
Invariably they are usually coyote or a coyote/canine mix. Feral and quite sick. Parasites, mange...etc.
I haven't seen it reported to by anything other than a sick coyote or a sick coyote/canine mixture once the DNA is completed.
It still saddens me when an animal has to be killed like this though.
ETA: In the video it's reported that the animal did charge the officer, sounds like maybe rabies too? I like coyotes.
