A post mortem revealed the mother of five died from natural causes before the dog\'s attack. A police spokeswoman said: \"It established the injuries were caused after she had died. \"A juvenile dog has been destroyed following consultation with the family. An elderly German Shepherd in another room was not involved in the incident.\" Cassie\'s death was originally reported as the result of a dog attack by the family\'s pet Alsatian. This was untrue and we apologise for our original report.
