Suspect relationship mapping

Criminal investigations hinge on understanding the relationships between people, organizations, locations, communications, vehicles, and financial transactions. MemoryJar's typed entity system lets investigators build structured relationship maps that go far beyond what a whiteboard or spreadsheet can capture. Create person nodes for suspects, witnesses, and victims. Link them to organizations, addresses, phone numbers, vehicles, and bank accounts. Each relationship edge can be labeled — associate, employer, family member, co-conspirator — and annotated with sourcing information. The graph view makes it immediately apparent which suspects are central to the network, which connections are indirect, and where gaps in the investigation exist. The outline view provides a parallel hierarchical structure for organizing case notes, witness statements, and documentary evidence.

Evidence chain visualization

Building a prosecutable case requires documenting the chain of evidence from collection through analysis to presentation. MemoryJar lets investigators attach rich-text notes to every entity in the graph, documenting where each piece of evidence came from, who handled it, and how it connects to other elements of the case. Create evidence nodes linked to the suspects, locations, and events they relate to. Attach photographs, scanned documents, and surveillance imagery directly to nodes using the image embedding feature. The graph makes it easy to demonstrate how individual pieces of evidence connect to build the overall case narrative. Export the complete workspace as a structured JSON file for archival, or generate Markdown reports for case files and court submissions.

Timeline reconstruction

Reconstructing the sequence of events is critical in criminal investigations, fraud cases, and civil litigation. MemoryJar's entity system lets you create event nodes anchored to specific dates and times, then link them to the people, locations, vehicles, and communications involved. The graph view shows how events connect across the timeline — which suspect was at which location, which communications preceded which actions, and how the pattern of activity builds the narrative. Investigators can switch between the graph view for visual pattern analysis and the outline view for chronological documentation, maintaining a dual perspective on the same underlying data.

Secure and compliant

Law enforcement data requires strict handling controls. MemoryJar runs entirely offline as a portable desktop application. No data is transmitted to any cloud service. All case information is stored locally on the investigator's machine in an encrypted database. The application requires no installation and no internet connection, making it suitable for use on secured law enforcement networks and evidence processing workstations. For multi-investigator cases, the LAN collaboration mode enables shared workspaces without any data leaving the agency's network. The portable executable format means the application can be deployed on any approved workstation without requiring IT department involvement or administrative privileges.
