Murder of ex-partner and disposal in wastewater tank
Jealousy
The case involves a violent escalation of jealousy by an ex-lover who killed the victim due to her involvement with another man. The suspect planned the crime carefully, including attempts to avoid CCTV detection and disposing of the body in a difficult-to-find location related to his occupation. This pattern reflects possessiveness and lethal violence following a breakup.
Police investigation relied heavily on CCTV footage to track the suspect and victim's movements. The suspect was arrested on assault leading to death charges and confessed fully. The body was recovered from a wastewater treatment tank at a waste disposal company where the suspect worked. The suspect's phone history showed searches on avoiding CCTV and crime planning. Psychopathy diagnosis tests are planned.
No significant confusion reported; the suspect was identified and arrested based on CCTV evidence and confessed to the crime.
The victim left work on November 14 and was last seen entering her SUV. Contact was lost with her after that. Her child reported her missing on November 16. Police tracked the suspect Kim via CCTV, who disappeared along with the victim's SUV. On November 26, Kim was arrested and confessed to stabbing AC multiple times due to jealousy over her seeing another man. He wrapped the body in a burlap sack and disposed of it in a wastewater treatment tank at his workplace. The police confirmed the disposal location through CCTV tracking of the SUV's last movements.
High risk due to prior planning, use of weapon, and extreme violence motivated by jealousy and relationship dissolution.
Jealousy and obsession can lead to lethal violence even among older adults. Careful crime planning and use of occupational knowledge to conceal evidence complicate investigations. CCTV surveillance and digital footprints are critical in solving such cases.
The victim's loss of contact and the suspect's prior phone searches on crime planning and CCTV avoidance were key early signals.
CCTV footage tracking the victim's SUV and suspect movements helped connect the case.
CCTV recordings and the suspect's phone search history were the strongest evidence types.
