Season 13 of the groundbreaking drama begins exactly where season 12 left off as Russell's granddaughter Kaitlyn has been kidnapped by someone working for incarcerated Jeffrey McKeen. Morgan's father has been shot and Finlay is being tailed by a dirty detective. Russell is torn between confronting McKeen in prison and working the crime scene where Kaitlyn was taken, but he ultimately decides it will be more useful to let the evidence lead him to her. Following the trauma, Finlay encourages Russell to mend fences with his wife, but it turns out his wife is unhappy in Las Vegas and has gone to Seattle to spend time with her family. Other cases tackled by the CSIs in the thirteenth season include a massacre at a local diner that leaves but one survivor, the death of a fourteen year old girl killed at a large desert rave, and the murder of a famed music historian whose body was stuffed into a piano left in the middle of the desert.
