Deep Dive
Why is it particularly challenging to investigate unidentified corpse cases?
Unidentified corpse cases are difficult to investigate because the deceased's identity is unknown, making it hard to apply standard investigative methods like examining social relationships to determine motives. Additionally, environmental factors like water damage or decomposition can obscure critical evidence.
What key evidence was found in the Sichuan Fu River floating corpse case?
In the Sichuan Fu River case, a male corpse was found with multiple head injuries and a 30 kg cement block tied to the body, suggesting the body was intentionally submerged. The complex binding method indicated the involvement of multiple individuals, ruling out suicide.
How did investigators determine the murder location in the Sichuan Fu River case?
Investigators used water flow data from a nearby hydroelectric station to estimate the body's drift distance, narrowing the murder location to within 2 km upstream of the discovery site. They focused on Shengli Island due to its ongoing development, lack of surveillance, and proximity to the river.
What forensic findings helped in the investigation of the Taiyuan kiln skeleton case?
Forensic analysis revealed the victim likely died from mechanical asphyxiation, supported by 'rose teeth' and punctiform hemorrhages in the heart and lungs. Additionally, a smooth neck wound suggested sharp force trauma, complicating the death cause determination.
What crucial DNA evidence led to solving the Sichuan Fu River case?
DNA evidence collected from a local police station, initially unmatched, was successfully matched upon re-examination, identifying the victim as Tian Guichang, a 41-year-old divorced man with no fixed residence or job, previously involved in a minor altercation at a karaoke bar.
