On April 30, 2009, an elderly couple was found dead in a quiet rural village. The couple passed away simultaneously without any particular illness. A day before their death, a 77-year-old woman, 박혜자 (pseudonym), who lived in the apartment below, was also found dead. With three people in a small village dying consecutively, an investigation was initiated. The autopsy revealed that all three deaths were due to cyanide poisoning. What on earth happened in this village?

While thoroughly searching the crime scene again, police discovered an unexpected clue. Folded newspaper was placed in front of the elderly couple's fireplace. When carefully unfolded, it revealed a suspicious note; who could have left this? And why did that person leave this note and vanish? During their ongoing investigation, the police heard crucial testimony from village residents and eventually identified a strong suspect. 이지혜 said, "How could such a thing happen in the same village?" She expressed her anger, saying, "After hearing the story, the perpetrator is so shameless and brazen." 안현모 marveled, noting, "In a situation where the suspect denies everything, the lead investigator discovered an incredible smoking gun through cunning."

Meanwhile, on that day's broadcast, Boryung Police Station Investigator 전병화 appeared to discuss the intense investigative process he undertook to prove the crime, and toxicology expert 김선춘 explained the scientific basis of cyanide toxicity, providing detailed context for the verdict.

The cyanide poison incident that shook the small village, "'Leave Behind Recovery Supplement ' - Boryung Cyanide Murder Case" will be aired at 9:45 p.m. on the 3rd on KBS2's "Smoking Gun."
