Worth the recommendation?

Wells and his wife got the support of friends during this time. In fact, it was a friend who recommended McKenzie to them. During their visit, both he and his wife were clearly unsatisfied with the lack of answers from the police’s end. The moment they visited the talented clairvoyant, they got more than what they expected.

The details

McKenzie gave an unnerving yet precise account of what happened on the day the girls disappeared. He told them that the murder involved one male and one female. He even described how the suspects looked. He further stated that he could see a red car being used to move the girls’ bodies somewhere so that these could be hidden in a ditch. Who exactly were these killers and was McKenzie correct?
