Ep 10. Keys To A Killer

In Mark of a Killer season 2 episode 10, titled Keys To A Killer, the focus is on the brutal murder of a college student named Brooke Wilberger back in 2004. The case went cold for years until a man named Joel Courtney emerged as a suspect.

Joel Courtney was a transient criminal living in the area at the time of Brooke's disappearance. He had a long history of sexual assault and burglary, and investigators quickly honed in on him as a potential suspect. But the case against him was largely circumstantial, and it took years to build a solid case.

The episode delves into the details of how investigators used everything from DNA evidence to cell phone pings to close in on Courtney. They also interview members of Brooke's family and the detectives who worked tirelessly on the case for years.

One of the key pieces of evidence in the case was a set of keys found in Courtney's possession. These keys belonged to Brooke, and they were found during a search of his home in 2009. The episode details how investigators were able to connect these keys to the murder, and how they helped build a case against Courtney.

Throughout the episode, viewers get a sense of the tension and frustration that surrounded the investigation. For years, Brooke's family had no answers about what had happened to their daughter, and investigators had a difficult time building a case against a suspect who was often on the move.

The episode also explores the psychology of a killer like Courtney, who had a long history of violent behavior towards women. Viewers get a sense of how he was able to evade capture for so long, and how he was finally brought to justice.

Overall, Keys To A Killer is a gripping and emotional episode that sheds light on the painstaking work that goes into solving a complicated murder case. It serves as a reminder of the importance of persistence and diligence in the face of seemingly insurmountable obstacles.
