On April 17, Susan Elaine Rancourt disappeared while on her way to her dorm room after an evening advisors' meeting at Central Washington State College in Ellensburg, 110 miles (175 km) east-southeast of Seattle. Two female Central Washington students later came forward to report encounters—one on the night of Rancourt's disappearance, the other three nights earlier—with a man wearing an arm sling, asking for help carrying a load of books to his brown or tan Volkswagen Beetle.
On 21 April 1974, while the painting was on display at the Tokyo National Museum, a woman sprayed it with red paint as a protest against that museum's failure to provide access for disabled people.
