Strengthening Forensic Laboratory Methods in Solving Murder Case Without Witnesses: Case Study Polrestabes Bandung Jurisdiction

This study examines strengthening Scientific Crime Investigation (SCI) approaches through forensic laboratory methods for solving witness-less murder cases in Polrestabes (Metropolitan Police Resort) Bandung’s jurisdiction. The case study focuses on Police Report LP/B/421/XII/2024/JBR/Restabes BDG/Sektor Batununggal, involving victim MMY who died from neck slashing and back stabbing by an unknown perpetrator.
