On 16 April 2017, Peter Dansie took his then 67-year-old wife Helen out of her nursing home and drove her to Veale Gardens in Adelaide where there are several rock pools.

At 6.26pm he called emergency services, stating that Helen's wheelchair had fallen into a pond and she had drowned.

He was later charged with his wife's murder. The evidence in this case was largely circumstantial. Was it an accident or was it carefully planned by Peter to free himself from a wife he no longer wanted?
