Investigations rarely lose momentum because of a single mistake. More often, they slow down gradually. Detectives stay busy, but progress becomes harder to measure. Conversations shift from theories and leads to questions like, “Are the calls reviewed yet?” or “Did the extraction finish processing?” The work continues, but the case itself is no longer moving forward.

That drift usually has one root cause: the volume of digital evidence has grown beyond the workflow built to manage it. These breakdowns are not dramatic. They accumulate quietly until days or weeks have passed, and by then the impact is already visible across interviews, follow-ups, and charging decisions.

Evidence Volume Outpaces Sequential Review 

Cases still begin in familiar ways, a burglary, an assault, a shooting. What breaks workflows is what arrives next.

If you work investigations today, you’ve opened inboxes containing hours of body-worn camera footage, multiple device extractions holding years of messages and app data, social media warrant returns spanning thousands of pages, and unlabeled folders of images and video clips. National Institute of Justice guidance confirms digital evidence now appears in nearly every crime type, not just cyber cases.

Traditional sequential review made sense when evidence fit one folder. Today the caseload math no longer works:

• One detective typically manages 15-25 active investigations

• Average case requires 45 hours of digital review

• Manual workflows collapse under that sustained volume 

When investigators spend most of their time just opening files and navigating formats, less attention reaches the connections that actually solve cases.

Late Context + Fragmentation Creates Drift 

You’ve probably experienced this: a key detail surfaces weeks after your first interview. A confession buried deep in call lists. You pick up a cold case that’s been worked by four different detectives - all retired. A timeline contradiction hiding in thousand-page PDFs. Images that change everything, discovered after witnesses are already debriefed.

Police1 reports investigators now describe their work as “digital triage,” routinely skipping evidence portions just to maintain case velocity. Early decisions get made on partial information:

• Interviews proceed without critical background

• Follow-ups target incomplete leads

• Prosecutors receive technically accurate but fragile case updates

None of this reflects a lack of effort. When evidence review lags behind case momentum, every downstream step rests on incomplete context. Cases don’t stop, they drift.

Fragmentation Turns Verification Into Parallel Work

The real challenge isn’t evidence complexity. It’s fragmentation across disconnected systems.

A jail call timestamp aligns with an interview statement. A screenshot contradicts a suspect claim. A video shows a location mentioned in a transcript. Investigators know these connections matter, but tracking them manually across separate tools exhausts cognitive bandwidth.

Verification becomes its own investigation. Digital forensics programs report analysts spend most time on these steps:

• Relocating the exact insight moment

• Confirming surrounding context

• Validating original source file

• Documenting clearly for prosecutors 

Supervisors notice when updates slow. Prosecutors notice when sourcing requires extensive reconstruction. Cases lose momentum not because evidence doesn’t exist, but because defending it takes longer than finding it.

Capacity Declines While Workloads Grow

Investigative teams face evidence growth from one direction and capacity pressure from every other.

PERF’s 2023 staffing survey found sworn officers down 5% from 2020-2022, resignations up nearly 50% vs pre-2019 levels. Cellebrite’s 2024 digital forensics survey showed 67% reporting growing workloads, 52% expecting worsening backlogs.

Municipal budget pressures compound this, expenditures now outpace revenues, leaving investigative vacancies unfilled and digital forensics under-resourced. The result: more data arriving faster than the hours available to process it.

Agencies Adjusting Through Workflow Changes

Leading agencies aren’t solving this through longer hours. They’re changing how work advances  from intake forward.

Common patterns among teams keeping pace:

• Triage immediately - context builds as evidence arrives, not after full datasets complete

• Relevance-first - focus on key people/times/locations vs opening files by load order

• Unified formats - audio/images/docs/video form one narrative view early

• Source-linked insights - notes tie directly to original files for instant verification

These changes protect what investigators do best. Interviews sharpen with better context. Follow-ups happen sooner because leads surface earlier. Prosecutors receive clearer updates with stronger sourcing. The workflow finally matches the evidence scale.

Leaders frame the goal simply: reduce data-heavy administrative time, maximize judgment and community knowledge where they matter most.

But any new tools must meet investigator standards: traceable insights, defensible conclusions, security compliance. Next, we’ll examine what investigators need from AI tools to trust them in mission-critical workflows, focusing on verification, defensibility, and CJIS-aligned security that holds up under courtroom scrutiny.
