Ep 12. Butterfly Effect

Carrie Wells and Al Burns have been called in to investigate the murder of a college professor. While the motive behind the murder remains unclear, what immediately grabs their attention is the oddness of the crime scene. There are no signs of forced entry, the victim's laptop is missing, and a butterfly is found on the victim's body.

As Carrie and Al begin to dig into the case, they discover that the victim had recently published a paper on the Butterfly Effect, a phenomenon that describes how small changes in one area can have drastic effects on another. Through their investigation, they begin to suspect that the murder is linked to the victim's research and that his findings may have led him down a dangerous path.

Meanwhile, Carrie is still struggling with her own personal issues, particularly her strained relationship with her sister, Rachel. She turns to her ex-boyfriend, Eliot, for support, but their reunion quickly turns sour when he reveals that he's engaged.

As the case progresses, Carrie and Al uncover a string of suspects with motives ranging from academic rivalry to revenge. When a second murder occurs, they realize that time is running out to catch the killer before they strike again. With the help of the team, including medical examiner Joanne and tech expert Mike, they manage to connect the dots and bring the killer to justice.

But even as they close the case, Carrie can't shake the feeling that there's more to the story. As she continues to grapple with her own past and her family relationships, she begins to see the Butterfly Effect in action in her own life. In the end, she realizes that sometimes, the smallest decisions can have the biggest consequences.
