Sensing Murder - Season 4

This week, for the first time ever, the prime suspect in a murder enquiry has turned to Sensing Murder for help. Since 1977, farmer Lindsay Calvert has had to endure local suspicion that he murdered his wife Lesley, who was missing for seven months before her body turned up in an area that had already been searched. Although the coroner ruled that Lesley died from 'unknown causes', and the police thought she had probably committed suicide, Calvert is still convinced that his wife was murdered. Calvert is adamant that he adored his wife. "It was everything I ever dreamed a relationship would be," he says. "We were soul mates - and she was a fantastic mum." Soon after Lesley's disappearance, some local people started to speculate on his possible involvement in the crime, and disturbing things began happening in the Calvert household. "We had a house cow shot. We had four sheep shot up here by the stock yard - gut shot at that, which is very cruel," Calvert explains. "My kids had two pet goats, they both disappeared." His daughter, Sandra Calvert also remembers the unsettling occurrences. "We'd go down to our grandparents for dinner and we'd come back and things had been moved in the house. Things had been pulled out of the hot water cupboard - it was scary." Now, frustrated by the years of suspicion, Calvert wants the psychics to clear his name and unmask the real killer. Psychics Webber and Cruickshank travel into the heart of Taranaki King Country in search of answers about Lesley's mysterious death.

In 2004 Brendan Percy was found dead of hypothermia and dehydration in a sub alpine area above Oamaru in suspicious circumstances. Psychics Kelvin Cruickshank and Sue Nicholson go to new heights to uncover the truth about Brendan's death.
