Jeremy Hainsworth is a Vancouver-based freelance journalist who writes for the Associated Press, Bloomberg News and a variety of civil rights news outlets. He covered Canada's worst serial murder trial that of pig farmer Robert Pickton. Hainsworth experienced horrendous nightmares during this time, self-medicated with illegal drugs and later suffered a mental breakdown. He was diagnosed with post-traumatic stress disorder as a result of covering the Pickton case and years of crime reporting where he attended scenes of murder, suicide and fatal car accidents. The overwhelming majority of news people whose lives and careers are touched by traumatic stress are not covering brutal wars or natural disasters in distant lands. They are mostly domestic journalists who witness car accidents, murder scenes, suicides and plane crashes. Trauma suffered by police reporters is an under-reported and stigmatised issue. It is often forgotten or widely unacknowledged that like policeman and paramedics, journalists are first responders to daily scenes of horror. Admitting to experiencing trauma to newsroom colleagues, however, is widely denounced within the industry. Haunted Witness reveals how Hainsworth suffered in silence while management showed a shocking lack of support for his mental health and wellbeing. His story shines a light on the failure of media organisations to properly monitor and manage the mental health of their staff.
