鸚鵡護主，攻擊兇手頭部，留下血迹，成爲定罪鐵證。

一隻鸚鵡護主時被殺，留下兇手血迹，成爲定罪證據。 一隻巴旦鸚鵡，（從新聞照片看是巴旦），名叫“鳥兒”。2001年12月24日在達拉斯市郊，當兇手殺害主人的時候飛到兇手頭上，猛叨兇手頭部。兇手用手抹去頭上的血迹，然後碰了一處開關，在犯罪現場留下了DNA. 此外，兩把殺死被害人的刀子上也發現了兇手的DNA。2003年2月18日兇手被判處終身監禁。 檢察官說：“鳥兒會說話，是它告訴我們。我們瞭解這種鳥會攻擊任何襲擊主人的人。” 兇手早先說他用一把叉子捅了鳥兒，因爲鳥叨他的頭。 Murderer convicted by evidence of pet cockatoo By Leyla Linton Court TV 20 February 2003 A pet cockatoo killed trying to protect its owner from an attacker produced evidence which helped to convict the murderer. The white-crested cockatoo, called Bird, flew at Daniel Torres as he stabbed Kevin Butler in the chest and abdomen and cut his throat. The pet pecked the killer on the head during the attack in the Dallas suburb of Pleasant Grove on 24 December 2001. Torres then wiped the blood away and touched a switch, leaving his DNA at the crime scene. His DNA was also found on two knives used in the attack and he was convicted on Tuesday of murder and sentenced to life in prison. George West, for the prosecution, said: "The bird spoke, he spoke to us. We know this bird will attack anybody who is attacking his owner." Torres had said earlier that he stabbed the bird with a fork because he had pecked him on the head. But he later denied this account and blamed the crime on his half-brother, who is to stand trial later. He had worked for the victim's pool company and had a falling out with Mr Butler, Torres said. Phillip Linder, for the defence, said he did not think the cockatoo had swayed the jury's decision. There was sufficient evidence to secure a conviction anyway.
