Sage Mears

The team of investigators tries to capture a serial arsonist who has been terrorizing a college campus in Tempe, Arizona. Most of the evidence from the fires had been burned beyond recognition, so the BAU must rely on psychological analysis to identify the firestarter.

When a young, female dockworker is found dead, the team discovers that the dock has mob connections that may lead to Maura's biological father (guest star JOHN DOMAN - The Wire, Borgia, Damages). Jane tries to evade sensitivity training. And Maura starts spending time with Jane's brother Tommy (recurring guest star COLIN EGGLESFIELD), much to Jane's dismay. ED BEGLEY JR. (St. Elsewhere, Pineapple Express) also guest stars.

In a continued effort to find Colleen McGrath (recurring guest star Audrey Marie Anderson), a missing young mother who had recently been recruited as a drug mule (someone who swallows pellets of illegal substances that are wrapped in condoms or latex gloves, travels to another country and then delivers the drugs), Samantha goes undercover as a woman with similar grim financial circumstances hoping to be approached by the same drug traffickers. Soon after Samantha takes a job at the retail outlet store where Colleen worked, Danny connects the outlet store's manager to another drug mule who was killed two years earlier. After getting the manager to reveal the identity of his boss, Samantha takes a job at the plant where the drug trafficker is seeking recruits. Once there, Samantha convinces Jack to let her go deeper undercover after she is recruited to be a heroin courier.
