Attacks on Internet-of-Things (IoT) devices have grown immensely and there is an urgent need to empower Digital Forensic Investigators (DFI) who are tasked to investigate such attacks. In this accepted journal paper, we conduct a user study with 39 digital forensic investigators from both public and private sectors to document the challenges they faced in traditional and IoT digital forensics. We also created a tool, Stitcher, that addresses the technical challenges faced by investigators when handling IoT digital forensics investigation. The efficacy of Stitcher is confirmed by our study results where 96.2% of users indicated that Stitcher assisted them in handling the crime, and 61.5% of users who used Stitcher with its full features solved the crime completely.
