Overview

• Cold Case: The Tylenol Murders debuted on Netflix on May 26, 2025, renewing focus on the cyanide-laced capsules that killed seven Chicago-area residents in 1982.
• The documentary includes James William Lewis’s last recorded interview before his 2023 death, plus firsthand accounts from victims’ family members and former law enforcement officials.
• Filmmakers explore alternative theories, notably the possibility of factory-line contamination at a Johnson & Johnson plant, and revisit other persons of interest.
• In response to the killings, federal law mandated tamper-evident seals on over-the-counter medicines and spurred Johnson & Johnson to lead industrywide packaging reforms.
• Despite four decades of investigation and these new perspectives, no arrests have been made and authorities suspect there may be additional, undetected victims.
