 eMJA: Byard et al, Dolphin deaths: forensic investigations
For example, in a previously investigated case in 1999, forensic examination of an infant dolphin showed that the animal had died after being speared to death (Box 5) and enabled the approximate dimensions of the weapon to be determined.
For the dolphin in Case 1, death was attributed to a stab wound inflicted to the heart, most likely by a knife or similar single-edged sharp weapon.
This means that the examination of each dead dolphin was undertaken in a similar fashion to a standard human autopsy in a suspicious case, including accurate documentation of times, personnel present and possible trauma.
