Jasper, a four-year-old Tasmanian devil, was killed at a zoo in Albuquerque, New Mexico, according to ABC News.

It is unknown who or what killed the Tasmanian devil, but the facts that have emerged are reportedly leading to speculation that the animal may have been attacked by a human.

When Zoo staff initially found Jasper's body on Wednesday, they reportedly did not suspect foul play.

"The first suspicion of how the devil died was that it was possibly killed by another devil," the police report states.

It continues, "After the necropsy was completed the veterinarian Ralph Zimmerman found a small piece of the devil's skull fractured, staff went back into the enclosure."

Two large chucks of asphalt were reportedly discovered in the pen, adding to the facts of the case. Police then suspected that the Tasmanian devil was killed by someone who hit it with a piece of asphalt after entering a roped-off area, according to an Albuquerque police report.

Jasper was reportedly one of four provided to the Albuquerque BioPark Zoo last year by the Healesville Sanctuary as part of an effort to start a breeding program for the endangered species, according to the Albuquerque Journal. The Tasmanian devils have reportedly been killed off on the island of Tasmania south of the Australian mainland due to a form of cancer that had been spreading, according to the Associated Press.

As it's unclear whether Jasper was killed by a human or another animal, an independent investigator has reportedly been assigned to help police with the case.

"It looks like there was malicious intent and essentially our poor Tasmanian devil was killed, intentionally, by what seems to be blunt force trauma to the head," Albuquerque mayor's chief-of-staff, Gilbert Montano told KRQE-TV.

Facts emerging regarding the death of Jasper have upset many people.

"Upon hearing about it, the mayor was shocked, outraged, extremely concerned. These little guys are an endangered species," stated Montano.
