Lore & Background
Carlyle Harris married Mary Helen Potts on February 8, 1890. He later killed her with an overdose of morphine in the form of sleeping pills. Although her death was first attributed to a stroke, physicians discovered the murder because she displayed severely contracted pupils, a characteristic symptom of morphine poisoning. Harris was prosecuted by Assistant District Attorney Charles E. Simms Jr., with witnesses including Dr. Rudolph Witthaus. He was represented by prominent defense attorney William F. Howe. Harris was found guilty of first degree murder on February 8, 1892, the second anniversary of his marriage to Helen Potts, and was executed in the electric chair at Sing Sing Prison on May 8, 1893.
Reader's Guide
The case of Carlyle Harris is significant as a historical example of murder by morphine overdose being detected through the telltale sign of contracted pupils, a symptom that led physicians to question the initial stroke diagnosis. The trial involved notable figures: Assistant District Attorney Charles E. Simms Jr. prosecuted, while prominent defense attorney William F. Howe represented Harris. Dr. Rudolph Witthaus testified as a witness. The case also left a cultural legacy: journalist Algernon Blackwood, who had been a police reporter for the New York Times during the trial, wrote the story 'Max Hensig, Bacteriologist' based on the events. Additionally, journalist and author Bernard Barshay wrote 'The Case of the Six Capsules' based on the trial, which was later recorded on the record 'Four American Murder Mysteries.' The case thus contributed to both forensic medical history and popular crime literature.
