A series of bombings rocked Salt Lake City in 1985. First, businessman Steve Christensen was killed by a bomb left outside of his office. Then Kathy Sheets was killed by a similar bomb at her home. At first, the motive appeared to be business - the second bomb was addressed to Kathy’s husband Gary Sheets, former business partner of Steve. When a third bomb went off, injuring documents dealer Mark Hofmann, the case became more complicated. Investigators would soon find themselves unraveling a web of forgeries and cover-ups, using forensic document examination to crack the case. Hosts: Colleen O’Brien, Erica White.

In 1986, Susan Snow died after taking Excedrin capsules contaminated with cyanide. Her death prompted a recall and an investigation, which turned up more bottles of poisoned pills. 2 of those bottles were at the home of Stella Nickell. Her husband Bruce had recently died, and Stella insisted his death be re-investigated in light of Sue’s death. When it was found that Bruce also died of cyanide poisoning, investigators worried there was a serial poisoner at work. The truth was that only one person committed the poisonings, and the identity of the killer would be revealed by some tiny green crystals. Hosts: Colleen O’Brien, Erica White.

In July 1991, a janitor discovered burned remains in a dumpster in Vancouver. The remains were so damaged by the fire that dental records were the only possible method of identification. The remains were those of a missing woman named Mary-Lynn Breeden. Bank surveillance footage and questioning an accomplice led investigators to the man they believed killed Mary-Lynn. To convict him, scientists would have to find a source of DNA that had never been used before. Hosts: Colleen O’Brien, Erica White. Audio Supervisor: Tommy O’Brien.
