In the summer of 1993, a chilling series of events unfolded in Mason City, Iowa, culminating in the death of 34-year-old Greg Nicholson. A male resident of the city, Nicholson found himself entangled in the dangerous world of methamphetamine trafficking, a connection that would ultimately cost him his life. His story is not just one of a drug deal gone wrong but a calculated act of witness elimination that silenced multiple voices.
Nicholson had been arrested on federal drug charges and,
in a bid to seek leniency, agreed to cooperate with authorities and testify against his supplier, Dustin Honken, a significant methamphetamine producer in the Midwest. This decision sealed his fate. On July 24, 1993, just days before he was scheduled to testify, Nicholson disappeared. He was not the only one to vanish. With him were his girlfriend, Lori Duncan, and her two young daughters, 10-year-old Kandace and 6-year-old Amber.
For years, their disappearances remained a haunting mystery, a cold case that left a community with unanswered questions. It wasn't until the year 2000 that the grim truth was unearthed. The bodies of Nicholson, Duncan, and her two children were discovered buried in a shallow grave in a wooded area southwest of Mason City. Investigations revealed they had been brutally murdered. Honken, with the help of his girlfriend, Angela Johnson, had orchestrated the killings to prevent Nicholson from taking the stand. The couple had gone to Nicholson's home where they subdued him and Duncan. The children were tragically killed because they were witnesses.
The unraveling of the case led to the arrest of both Dustin Honken and Angela Johnson. Honken was ultimately convicted of the five murders, including that of another informant named Terry DeGeus who was killed months after Nicholson. He was sentenced to death and was executed by lethal injection on July 17, 2020. Angela Johnson was also convicted for her role in the murders and received a death sentence, which was later commuted to life in prison.
