On the morning of November 5, 1871, a stagecoach traveling west from Wickenburg, Arizona Territory, toward California was attacked several miles outside Wickenburg along the La Paz road. Six people were killed, including the driver and Frederick Wadsworth Loring, a young Boston writer working as a correspondent while covering Lieutenant George Wheeler's cartographic expedition.
The attackers' identity was never established in court. Contemporary authorities attributed the attack to Indigenous men from the Date Creek Reservation, described inconsistently in period sources as Yavapai or Apache-Mohave. Later historical accounts have questioned that conclusion because the physical and testimonial evidence was conflicting. No one was tried for the killings.
Two passengers, William Kruger and Mollie Sheppard, survived the initial attack with wounds.
William Kruger later reported that Mollie Sheppard died from her wounds.
Memorial plaques were later placed near the reported site. The Arizona Highway Department installed a plaque in 1937, and the Wickenburg Saddle Club installed additional memorials in 1948 and 1988.
