# Investigative Case Management **Aliases:** ICM **Entity class:** Federal investigative case-management system **Domain:** Homeland security / criminal investigations / information systems **Doc Type:** System Node **Maturity:** Developed ## Definition **Investigative Case Management (ICM)** is ICE's modernized electronic case-management environment for criminal and administrative investigations. It replaced relevant legacy TECS case-management functions with consolidated subject records, structured and unstructured search, de-confliction, workflow controls, electronic case files, and contemporary authentication. ## Architectural Significance ICM belongs to the source-system and case-management layer. It records and organizes investigative work under ICE authorities. [[wiki/ICEPIC|ICEPIC]] belonged to an analytical layer that correlated data and identified non-obvious relationships; the [[wiki/DHS Law Enforcement Information Sharing Service|LEIS Service]] belongs to an exchange layer that exposes selected information to authorized partners. The 2019 LEIS privacy assessment describes the service after ICEPIC and DPICS2 retirement as drawing from source systems rather than relying on the former centralized repositories. That is architectural continuity with a changed storage model, not evidence that every ICEPIC algorithm, field, or access path continued unchanged. ICM was deployed in 2016 on [[wiki/Palantir Gotham|Palantir Gotham]] as HSI's official investigative system of record. Its documented surrounding components included the [[wiki/PRIME Interface Hub|PRIME Interface Hub]], [[wiki/HSI Data Warehouse|HSI Data Warehouse]], [[wiki/Telecommunications Linking System|TLS]], and [[wiki/PenLink|PenLink]]. The 2026 modernization direction is the [[wiki/Case Management and Analytics Platform|Case Management and Analytics Platform]], which joins case workflow and investigative analytics over an [[wiki/Enterprise Lakehouse|Enterprise Lakehouse]]. ## Sources / Provenance - [[research/Immigration and Customs Enforcement Pattern Analysis and Information Collection (ICEPIC)|ICEPIC research dossier]] - [DHS — ICE Investigative Case Management PIA](https://www.dhs.gov/sites/default/files/publications/privacy-pia-ice-icm-june2016.pdf) - [DHS — Law Enforcement Information Sharing Service PIA](https://www.dhs.gov/sites/default/files/publications/privacy-pia-ice-leiss-july2019_0.pdf) ## Relationships - **operated by:** [[wiki/United States Immigration and Customs Enforcement|ICE]]. - **supports:** [[wiki/Homeland Security Investigations|Homeland Security Investigations]] and other authorized ICE users. - **modernized:** legacy [[wiki/Treasury Enforcement Communications System|TECS]] case-management functions. - **source-system role for:** [[wiki/DHS Law Enforcement Information Sharing Service|DHS LEIS Service]]. - **implemented on:** [[wiki/Palantir Gotham|Palantir Gotham]]. - **connected systems:** [[wiki/PRIME Interface Hub|PRIME]], [[wiki/HSI Data Warehouse|HSI Data Warehouse]], [[wiki/Telecommunications Linking System|TLS]], and [[wiki/PenLink|PenLink]]. - **modernized through:** [[wiki/Case Management and Analytics Platform|CMAP]].
