Cow commits the perfect crime

From The Telegraph

A grandmother has been killed in a freak accident after a cow barged against a gate which then hit her on the family farm.

Mrs Arnison-Newgass, who had two children and five grandchildren, and her 42 year old son Richard were tending a cow which had just given birth to twin calves when it barged against the gate. The gate swung through 90 degrees and slammed into her, the blow rupturing a growth on her liver.

This is getting scary. This cow had worked out how to use cow tools (i.e. a door) to kill a human being and to make it look like a 'freak accident' rather than murder. Let's hope they don't develop opposable thumbs or anything. Like dolphins.
