Forensic Files II 1 сезон 10 серия — The Letter

In 2015, a health-conscious chiropractor from Whitesboro, New York mysteriously dies. After Mary Yoder's autopsy shows the cause of death as colchicine poisoning, the investigation into her suspicious death becomes a homicide case. Digital forensics are used to tie Internet searches and an anonymous type-written letter to an unlikely suspect - her office administrator who was her son's ex-girlfriend.
