Hotch is off on leave, leaving Rossi in charge. Hotch has provided an electronic OK for Ashley Seaver to complete her remedial training at the BAU, she who wants to atone for the mistake she made in the strangled women case in New Mexico. With support from Prentiss who would act as Seaver's agent supervisor, Rossi provides his reluctant OK. Meanwhile, the parole board has asked the BAU to do a risk assessment on Don Sanderson, who has served his minimum twenty-five years of a life sentence for killing his wife and daughter. A former medical resident, Sanderson has always professed his innocence, telling a story of two men and a woman who he saw commit the murders. Rossi delegates the task of the risk assessment to Morgan, who sees in Sanderson a man who has lived solely for the sake of his now grown son, Joshua, and being able to tell him what he knows to be the truth. Morgan provides his approval for Sanderson's parole. Two days after his release, Sanderson is charged with the murder of Tom Wittman, who Sanderson admits to killing, but in self-defense. Garcia can't find any connection between Sanderson and Wittman prior to this altercation. To clear Morgan's good name, the BAU need to delve into the original murders of Sanderson's wife and daughter to find why Sanderson purposefully went to see Wittman.
