Voice of a Murderer (2007) Timeline Explained – Every Event in Order

The kidnapper, known as the Bastard's Voice, deliberately targeted Detective Kim Wook-jung to demonstrate his control and taunt the investigation. By capturing and torturing the lead detective inside a car trunk, the kidnapper sent a chilling message that he could reach anyone involved in the case. This act was meant to intimidate the police force and showcase his psychological superiority over the investigators, making it clear he was always one step ahead.

Foreshadowing: Earlier in the investigation, the kidnapper had already shown his ability to evade police surveillance and manipulate the timeline of events.

Lee Jae-joon, Han Kyung-bae's former best friend, was initially investigated as a suspect because he harbored a heavy grudge against Kyung-bae. However, he was ultimately cleared due to an airtight alibi that placed him elsewhere during the critical time frames. The police could not establish a direct link between him and the kidnapping, making it one of the red herrings in the investigation.

Foreshadowing: The film introduces Jae-joon early as a potential suspect with clear motive, creating initial suspicion before his alibi emerges.

A forensic audio expert revealed that one of the so-called proofs of life, the recording of Sang-woo pleading for his life, was likely manipulated or fabricated. This discovery forced police to reassess how much they could trust the audio evidence and reconsider their public strategy. The realization that the kidnapper could fabricate victim's voice recordings added another layer of psychological terror and uncertainty to the case.

Foreshadowing: The kidnapper's methodical nature and technical sophistication were established early through his careful phone handling and location switching.

The kidnapper directed the final delivery to a location near Lotte World, and Han Kyung-bae personally placed the ransom money at the specified site, believing his son was still alive. However, the exchange resulted in nothing, no reunion with Sang-woo and no further contact from the kidnapper. This failed exchange confirmed the worst fears of the family and investigators, signaling that Sang-woo was likely never coming back.

Foreshadowing: Throughout the investigation, the kidnapper consistently evaded every attempt to track or trap him during exchanges, demonstrating his cunning.

After Sang-woo's body was discovered on the 44th day near Han River park, Han Kyung-bae returned to his anchor chair to deliver the tragic news to the nation. In a final act, he shared a recording of the kidnapper's voice with the public, turning his personal tragedy into a public pursuit of justice. This broadcast aimed to keep public attention on the case and maximize the chances of catching the perpetrator.

Foreshadowing: Earlier, Kyung-bae had agreed to a public appeal to mobilize the city, showing his willingness to use his media position for the investigation.

The Bastard's Voice employed meticulous operational security throughout the 44-day ordeal. He never lingered on phone calls, constantly switched locations for each exchange, and maintained a cold, emotionless tone that revealed a calculating mind. His patience and methodical approach kept investigators constantly reacting to his moves rather than anticipating them, allowing him to stay one step ahead despite the massive police resources deployed.

Foreshadowing: From the first ransom call, the kidnapper demonstrated careful tactics by avoiding detection and keeping communications brief.

On the 44th day of the investigation, authorities discovered Sang-woo's lifeless body near a park along the Han River. This devastating discovery came after weeks of failed exchanges, manipulated audio proofs, and an exhaustive search. The timing, just as hope was fading, marked the tragic conclusion to the 44-day nightmare that had gripped the city.

Foreshadowing: The repeated failed exchanges and the kidnapper's silence in the final days had already hinted at the worst possible outcome.

The torture of Detective Kim Wook-jung was a pivotal moment that demonstrated the kidnapper's willingness to directly challenge law enforcement. Being captured inside a car trunk and subjected to physical torment not only traumatized the detective but also sent a powerful message to the entire police force. The incident intensified the urgency of the manhunt while showcasing the personal risks investigators faced confronting a calculated and dangerous criminal.

Foreshadowing: The kidnapper had already shown he could access information and manipulate the investigation from the shadows.

Once forensic experts revealed that the proof of life recording could be manipulated, the police had to fundamentally shift their approach. They could no longer trust audio evidence as confirmation of Sang-woo's survival and had to treat the case as potentially involving a deceased victim much earlier. This revelation also prompted them to reconsider how much information to release publicly, fearing the kidnapper might use fabricated evidence to mislead the investigation further.

Foreshadowing: The kidnapper's technical sophistication was evident in his ability to make and receive calls while constantly changing locations.

Han Kyung-bae agreed to a public appeal because the investigation had reached an impasse and conventional methods weren't yielding results. By mobilizing the entire city through a televised appeal, he hoped to generate public pressure and gather new leads. As a prominent news anchor, Kyung-bae understood the power of media and used his position to amplify the search, transforming his personal crisis into a community effort.

Foreshadowing: Earlier in the film, the police had formed a secret task force and forensic unit, yet the kidnapper continued to outmaneuver them.

The film does not reveal the identity of the Bastard Voice, maintaining his enigmatic and calculating persona throughout the narrative. Despite the extensive investigation, the coordinated efforts of the police task force, forensic teams, and the public appeal, the kidnapper remains unidentified at the end. The only trace left behind is his voice recording, which Kyung-bae shares publicly in a final attempt to seek justice.

Foreshadowing: The kidnapper's careful operational security, never staying on calls, constantly switching locations, was designed to leave no identifiable trail.
