Relationship Pattern
Jealousy
Pattern Analysis
The relationship involved a long-term engagement with escalating tension due to financial insecurity, military service issues, and suspicion of infidelity. The fiancé's desertion and discovery of the victim's cheating led to a violent escalation resulting in murder. Family pressure and secrecy about military service contributed to the conflict.
Investigative Notes
Police investigation included missing person report, surveillance footage review, phone and bank transaction inquiries, and interrogation of the fiancé and his associates. The suspect surrendered voluntarily and confessed. Court proceedings led to a death sentence confirmed by the Supreme Court. Family refused to forgive, closing the case.
Investigation Confusion
Initial confusion arose from misidentification of a body and uncertainty about the victim's whereabouts. The suspect's desertion and disappearance complicated early investigation. No confusion about suspect identity after surrender and confession.
Case Reconstruction / Puzzle Pieces
Shabnam disappeared after university classes and taking a taxi to Azadi Square. Phone records linked her to Matin, who had deserted military service. Matin returned secretly, confronted Shabnam about infidelity, and killed her during a heated argument. He disposed of the body and fled temporarily before surrendering. The crime scene was reconstructed, and the case proceeded to court.
Risk Assessment
