Evidence Storage Solutions

Preserve Every Link in the Chain of Custody

Donnegan Systems offers evidence storage systems engineered to maintain the highest standards of security and accountability. From initial intake to long-term archival, our solutions are designed to protect the integrity of every item, support accreditation requirements, and enhance operational efficiency in law enforcement, public safety, and legal facilities.

Our modular configurations allow secure storage of diverse evidence—from small items to large, bulky objects—while locks, lifting-door controls, and temperature regulation help you comply with CALEA, IAPE, and other agency standards.

Short-Term and Long-term Evidence Solutions

Key Features of Evidence Storage:

Short-term and long-term evidence storage work hand-in-hand to support a seamless and compliant chain of custody from intake to resolution. Short-term lockers offer immediate, secure drop-off points that eliminate delays, reduce handling, and protect the integrity of items at the moment they’re collected—ensuring that evidence is safely transferred without compromise. Long-term systems, including high-density shelving and specialized cabinets, provide structured, space-saving storage that allows departments to manage growing evidence backlogs efficiently.

Short-Term Storage That Starts the Chain Strong

Our evidence lockers provide secure, temporary storage when it’s most critical—during intake and processing. Both Pass-thru and Non-pass thru lockers feature rugged 14–18 gauge welded steel, self‑closing doors with anti‑pry tabs, multi‑point latching, and keyless or electronic locking systems that track usage and support audit trails.

Long-Term Storage for All Evidence Types

Mounted on carriages that slide along rails, Spacesaver's high-density mobile systems eliminate unused aisles—often doubling storage capacity while ensuring individual bin and box access. Choose from manual, mechanical-assist, or powered units—with PIN or badge access—for secure controlled access.

Regulated Storage for Sensitive Items

Specialized lockers protect critical or hazardous evidence: Refrigerated Evidence Lockers maintain 38–42°F with digital alarms and locking shippable inserts—perfect for biological samples, narcotics, or perishable items. Narcotics Evidence Lockers offer ventilated compartments and HVAC integration to dissipate fumes safely, and Weapons Evidence Lockers secure firearms and ammunition with reinforced racks, double-lock features, and various size options.

Unbroken Chain of Custody

Every custody point—drop, retrieve, store—can be tracked with ControLoc® smart locks or audit-ready electronic locking. Pass‑thru designs block front opening when the rear latch is open, preventing unauthorized access to secured locker and custody pathways.

Built to Stand Up to The Test

Your shelving system should work hard — and look good doing it. With a wide variety of custom end panel options, Hamilton’s cantilever shelving allows you to match the surrounding architecture, color schemes, or branding of your space. Choose from wood veneers, high-pressure laminates, powder-coated steel, or even full-graphic panels to make a visual statement or subtly blend into the background.
