But by early November, the beast's remains had seemingly been identified as a coyote.
Texas State University biologists had been provided a tissue sample by San Antonio's KENS-TV, whom Canion had contacted when she discovered the carcass. Mike Forstner, a biologist, announced that the DNA sequence was a nearly identical match to a coyote's DNA. Scientists at the Department of Biology at Texas State University used the Beckman-Coulter CEQ 8800 DNA sequencer to arrive at this result, using the sample provided by the TV station (i.e. not from the head kept by Canion).
One person who disagreed with this identification was Canion, who assessed the DNA information as flawed. On her website, Chupacabra Headquarters, she wrote: "The Cryptid is ALMOST a match for a common coyote, but it is actually a greater percentile for a common terrier and a Saint Bernard." And what she found was neither of those. She announced she would go after more testing at the University of California in Davis, and that her website would post the results.
Results were soon forthcoming. In a January 22, 2008 e-mail to Greg Snook of Strange Magazine, Phylis Canion revealed them. After testing hide, tooth and tissue of the beast, UC-Davis's Veterinary Genetics Laboratory worked out that it was coyote (Canis latrans) on its mother's side and Mexican Wolf on its father's side. They were still trying to figure out why it lacked hair. Canion reacted: "They say it is a hybrid — I still say it is a chupacabra."
The mystery of hairlessness was also a concern at Texas State University, where further skin samples had been taken to solve this and presumably other questions.
