Rachanda was last seen watching television at her family's residence on the Santiam Pass in Sweet Home, Oregon at 10:00 a.m. on July 10, 1990. She has never been heard from again. Her mother was at work at the time of her disappearance. Rachanda's stepfather, John Arthur Ackroyd, is the last person known to have seen her. He said he came home during a break from work and asked Rachanda if she wanted to go for a ride with him. She said no and he left. When he returned to the house at approximately 12:45 p.m., Rachanda had vanished. Ackroyd was charged in Rachanda's murder in April 2013. He died in prison in 2016 and refused to disclose the location of Rachanda's body.
