Suzie Barnham-Keaton is a former meth addict who became involved in Horatio's personal life after revealing she had known his late brother. After Susie rehabs in Indiana and returns to Miami, Horatio learns that her daughter, Madison, is Raymond's child (episode 208, "Big Brother").
In a later episode, her daughter becomes terminally ill. Neither Horatio nor Susie are matches for a bone marrow transplant, but he convinces Yelina Salas (who had assumed Madison was Horatio's daughter before Horatio told her about Ray), to have her son tested. Presumably, Ray Jr. is tested and proves to be a match, and Madison is cured.
