According to the analysis, the immediate cause of death was a "pulmonary edema", while the fundamental cause of death was "mechanical asphyxiation due to compression and crushing of the thoracic abdomen with injuries to the vital organs".
The examination not only reveals multiple fractures – "the entire anterior rib cage," sternum, ribs – and injuries – "bruised lungs with rips in the pleura", "liver with a wide tear" - but also the bite marks of the animal: "The rounded marks of the external exam are compatible with the teeth marks of an orca. The morphology may be partially reduced due to the wetsuit worn by personnel during the work day",cautions the report.
On December 26, two days after the incident, the zoo distributed a written statement in which they invoked the"preliminary data", and stated that the body "did not present signs of violence, nor hitting or biting, being the lack of oxygen which appears to be the cause of death, ruling out an attack."
Three days later Loro Parque released another statement which then speaks of the injuries and the violence of the event,explains that "at the conclusion of the exercise, Alexis was pushed violently by the orca due to an unexpected reaction from the animal." In addition, it also states that the trainer of marine mammals "suffered injuries due to compression of the thoracic area, and thus lack of oxygen is the most probable cause of death."In this same report, Loro Parque states that "in reviewing the details it shows that the behavior of the animal did not correspond with how these marine mammals attack their prey in the wild, but rather with how they displace."
