Advanced Evidence System - Professional Crime Scene Investigation for FiveM

Transform law enforcement investigations on your FiveM server with the Advanced Evidence System, a comprehensive forensic investigation script featuring evidence collection, crime scene analysis, fingerprinting, DNA sampling, ballistics tracking, evidence storage, chain of custody documentation, and laboratory analysis. This professional-grade CSI system brings realistic detective work to your server, allowing police to collect physical evidence, process crime scenes, maintain evidence integrity, and build cases through forensic investigation rather than just witness statements.

What's Included

The Advanced Evidence System provides complete forensic investigation capabilities including evidence spawning at crime scenes, collection tools for officers, fingerprint analysis, DNA extraction and matching, bullet casing collection and ballistics comparison, evidence tagging and documentation, chain of custody tracking, evidence storage lockers, laboratory processing stations, case file integration, and admissibility checks for court proceedings. The system creates a realistic investigation workflow from crime scene to courtroom.

Perfect For

• Serious roleplay servers with active law enforcement
• Detective-focused communities emphasizing investigations
• Servers with court systems requiring evidence-based prosecution
• Communities wanting realistic CSI and forensic gameplay
• Servers moving away from instant-arrest mechanics
• Police departments with detective bureaus and crime scene units

Evidence Types Supported

• Fingerprints: Lifted from weapons, vehicles, doors, and surfaces
• DNA Samples: Blood, saliva, hair, and biological evidence
• Bullet Casings: Shell casings from firearms discharged at scene
• Ballistics: Bullet comparison and weapon matching
• Weapons: Firearms, knives, and instruments used in crimes
• Drugs: Controlled substances for testing and identification
• Documents: Papers, IDs, and written evidence
• Digital Evidence: Phones, computers, and electronic devices
• Trace Evidence: Fibers, residue, and microscopic materials
• Personal Effects: Items belonging to victims or suspects

Investigation Workflow

1. Officer responds to crime scene and secures the area
2. CSI unit deploys evidence collection equipment
3. Systematically search scene for potential evidence
4. Collect fingerprints, DNA, casings, and physical items
5. Tag each piece with case number and description
6. Photograph evidence in situ before collection
7. Transport evidence to police station with chain of custody
8. Store evidence in secure lockers preventing tampering
9. Submit evidence to laboratory for processing and analysis
10. Receive lab results with database matches and identifications
11. Link evidence to suspects and build prosecutable case
12. Present evidence in court proceedings with proper documentation

Framework Compatibility

• ✅ ESX Legacy - Full integration with ESX police jobs and inventory
• ✅ QBCore - Complete QB compatibility with police and item systems
• ✅ Police Scripts - Works with major police MDT and CAD systems
• ✅ Court Systems - Integrates with legal and justice roleplay resources
• ✅ Inventory Systems - Compatible with ox_inventory, qb-inventory, and others

Laboratory Features

The evidence lab provides professional analysis capabilities:

• Fingerprint comparison stations with AFIS database
• DNA sequencing and genetic profile matching
• Ballistics microscopy for bullet and casing comparison
• Drug testing and substance identification
• Trace evidence analysis under microscope
• Digital forensics for phone and computer data extraction
• Blood spatter analysis and pattern recognition
• Processing queues showing analysis time remaining

Database Systems

• Citizen Registry: Fingerprints and DNA from all registered citizens
• Criminal Database: Profiles of known offenders with prior evidence
• Firearms Registry: Ballistics data from registered weapons
• Case Files: Active and closed investigations with linked evidence
• Evidence Inventory: Comprehensive catalog of all stored evidence

Chain of Custody Tracking

Maintain evidence integrity with detailed logging:

• Who collected the evidence and when
• Transportation and handling records
• Laboratory processing and analyst information
• Storage location and access logs
• Court presentation and final disposition
• Prevents defense challenges based on mishandling

What Makes It Stand Out

The Advanced Evidence System transforms police work from simple arrests into comprehensive investigations requiring skill, patience, and proper procedure. Unlike basic police scripts where officers just handcuff suspects, this system demands crime scene processing, evidence collection, laboratory analysis, and documentation - creating realistic detective gameplay. The chain of custody tracking, database matching, and court integration ensure that investigations have consequences and meaning, making law enforcement roleplay substantially more engaging and rewarding for dedicated players.
