Ep 13. Nelson's Sparrow

In season 10 episode 13 of Criminal Minds titled "Nelson's Sparrow," the BAU investigates a series of murders that seem to be linked to a case from 30 years ago. The team is called to investigate when the latest victim is found with a piece of paper that has the name and address of a retired detective, who was involved in the original case. The detective, now suffering from Alzheimer's, has no recollection of the case or the paper found on the victim.

As the team delves deeper into the case from 30 years ago, they uncover a disturbing link between the killer's victims and the detective's son, who died in a car crash shortly after the original case was closed. The team begins to suspect that the killer may be seeking revenge for the death of his own son, who was a victim of the same crime.

To make matters worse, one of the team members, JJ, starts to experience flashbacks from her past as she worked on the original case as a child. The flashbacks reveal a connection between JJ's past and the killer, further complicating the investigation.

As the team races against time to catch the killer before he strikes again, they must also deal with their own emotional baggage from the past. Personal demons and memories resurface for many of the team members, as they confront the tragic events that shaped their lives.

In "Nelson's Sparrow," the Criminal Minds team once again showcases their expertise in profiling and solving some of the most complex cases. The episode also highlights the team's vulnerabilities and the toll that this job takes on their personal lives. With exceptional acting and a gripping storyline, "Nelson's Sparrow" keeps viewers on the edge of their seats and leaves a lasting impact long after the credits roll.
