Rich Jackson is the uncle and adoptive father of Sally Jackson.
He took in his niece after his brother, Jim, and sister-in-law, Estelle, died. During Sally's last year of high school, Rich died of cancer, leaving Sally to have to work small jobs because she had dropped out of high school to take care of him.
Percy mentions Rich when he arrived home from being expelled from Yancy Academy earlier in the school year.
Rich was a caring man who greatly cared for Sally.
