Included in its report was a study by a neuropsychologist, Nevzat Tarhan, who asks prosecutors not to disregard the possibility of telepathy causing severe distress and headaches in the victims, giving them a tendency to kill themselves, reports Hurriyet Daily News . Brainwaves could have been sent from 1.5km (just under a mile) away, Hurriyet quotes Tarhan as saying. The report apparently doesn't offer a clear answer as to whether the deaths were murder or suicide but it's been submitted to the Ankara Chief Prosecutor's Office for further investigation.
