Jimmy gets murdered in Dexter: Original Sin -Details of the killer, explored

The newly released prequel series Dexter: Original Sin continues to ignite curiosity among fans as Dexter Morgan's journey to become a serial killer vigilante has finally begun. The series premiered on December 13, 2024, and has completed its first four episodes.

As seen in Dexter: Original Sin, the murder of Judge Powell's young son, Jimmy Powell, takes center stage. Before this brutal murder, Jimmy was abducted on his way to Saint Theresa Catholic School.

His kidnapper, known as the White Mask Kidnapper, took Jimmy to an isolated dark place that looked like the interior of an old ship. Jimmy was kept in the dark and periodically given food. However, in a chilling moment, the kidnapper snipped off one of Jimmy's pinky fingers with scissors.

After sealing Jimmy's wound with a cigarette lighter and causing him immense pain, the kidnapper sent the child's finger to his father. Due to the pain and trauma, Jimmy lost consciousness and woke up after some time.

When he regains consciousness, Jimmy tries to escape the place but ends up getting attacked off-camera by the kidnapper. In a brutal and final assault, the kidnapper hit Jimmy with an ice pick, immediately leading to his death.

Following the murder of Jimmy Powell in Dexter: Original Sin, the kidnapper left him hanging from a bridge in Miami, wrapped in rope. The gruesome scene was witnessed by joggers, who immediately called the police and informed them bout the child.

Despite the police arriving on time, Jimmy couldn't be saved as he already died. Since Dexter Morgan was also present at the crime scene, he witnessed Jimmy's dead body and was shaken to his core. This was Dexter's first time seeing the dead body of a child.

Despite the emotional shift after Jimmy's murder, Dexter is tasked with solving another murder case of a prostitute. Meanwhile, Tanya's (Sarah Michelle Gellar) analysis revealed that Jimmy was killed somewhere else before he was hanged.

However, the police remain far from finding the killer in Dexter: Original Sin Episode 4 "Fender Bender." One theory about Jimmy Powell’s death points to Hector Estrada, a dangerous drug kingpin.

As seen in the original Dexter series, Estrada has a history with Harry Morgan, who investigated him years ago in connection with other crimes. It might be possible that the drug kingpin killed Jimmy to take revenge for Judge Powell's actions against the cartel.

However, his involvement in killing Jimmy in Dexter: Original Sin currently remains uncertain, leaving room for more theories. Additionally, the investigators haven't found any link between Jimmy's murder and the cartel, as they didn't make any demand either.

So, if not the drug kingpin, then who killed Jimmy Powell in Dexter: Original Sin? It might be possible that someone within law enforcement might be involved in the gruesome act, or it's a new serial killer in the bustling city.

The Miami PD will likely continue their quest to find out Jimmy Powell's murderer, as he wasn't a commoner but Judge Powell's young son. So, fans can expect the upcoming episode to explore more about the kidnapper and his identity.

Additionally, Dexter Morgan is about to kill Mad Dog in Episode 4, but he manages to escape and later gets struck by a car. The episode ended with a cliffhanger as it's unclear if Mad Dog is dead, leaving Dexter in a tense situation.
