Nonhuman perpetrators

Finally, wildlife forensics is not always used in criminal investigations against humans. In 2000, the remains of several individuals from the last population of the highly endangered hairy-nosed wombat (Lasiorhinus krefftii) were found in Epping Forest National Park in central Queensland. Analysis of DNA confirmed that seven individuals had been killed. The likely perpetrators were identified by the genetic analysis of nearby scats, which revealed microsatellite genotypes typical of dingoes (Canis familiaris dingo). When a wombat genotype that matched one of the dead individuals was amplified from one of the dingo scats, the evidence against the dingoes was compelling, although no prosecution followed! (Banks

As part of the investigation the lion was trapped, and DNA samples were taken from its claws and stomach contents. The recovered genotypes matched both of the victims, and investigators therefore concluded that this particular mountain lion was responsible for both attacks (source: California Department of Fish and Game).
