G.O. 6.01 - Criminal Investigation
Purpose
- Establishes a written directive governing the Norwich Police Department (NPD) criminal-investigation function.
- Ensures investigations are efficient, effective, thorough, and guided by clear administrative protocols.
Policy Overview
- NPD shall:
- Fix specific accountability for preliminary & follow-up investigations.
- Employ a case-screening system to decide which incidents merit follow-up.
- Maintain a case-management system within IMC/RMS.
- Systematically identify habitual and/or serious offenders (per C.G.S. §53a-40).
- Violations of the order yield only departmental administrative sanctions; criminal/civil liability remains governed by law.
Detective Division (General)
- Patrol officers are the primary first-responders to all crimes/incidents.
- Preliminary investigation begins on arrival of the first unit.
- Detective Division handles matters of increased complexity/duration requiring specialized skills.
- Command Structure:
- Detective Division Commander (appointed by Chief) oversees daily ops.
- Sub-units:
- Criminal Investigations.
- Narcotics Investigations.
- Criminal/Youth Investigations.
- Temporary assignments: Patrol officers with special skills/info may be detailed to the Division; Patrol & Detective Commanders submit eligibility lists to Chief.
When to Notify a Detective
- Patrol Supervisor must call the on-call Detective Supervisor upon verification of:
- Deaths other than obvious natural causes (incl. homicide, suicide, industrial, fatal traffic, suspicious overdoses, untimely death <65 w/ no clear medical cause, etc.).
- Sexual assaults involving force within 72 hr or any sexual assault needing scene processing.
- Armed/aggravated robbery.
- Serious-injury assaults.
- Kidnapping/abduction.
- Bombings, extortion.
- Child abuse with serious injury or need for immediate, in-depth child interview.
- Any injury likely to result in death under unusual/suspicious conditions (e.g., industrial accidents of questionable cause).
- Significant burglaries/home invasions or serial-crime M.O. (significant = loss/damage >\$5{,}000).
- Police uses of force causing death or risk thereof.
- Any other incident deemed necessary by the Supervisor.
- On Detective arrival, Patrol Supervisor must:
- Relinquish scene responsibility upon request.
- Brief detective(s) on all actions/info.
- Ensure patrol reports are complete.
Command-Level Notifications to the Chief of Police
- Shift Commander notifies Chief for:
- Homicide & attempted homicide.
- Police-related shootings.
- Abduction/kidnapping; home invasions; SWAT call-outs.
- Officer injuries requiring hospitalization.
- Fatal car crashes; mass-mutual-aid events (e.g., casino brawls).
- Critical incidents as determined by any Supervisor.
- Missing endangered persons; drownings; train derailments; mass-casualty or industrial disasters; large structure fires; major HQ equipment failures.
- Off-duty misconduct possibly leading to arrest.
On-Call & Availability System
- Detectives not staffed 24/7, but:
- Issued cell phones for rapid callback; must carry during off-time or advise if unavailable.
- Communications Center maintains home & cell numbers.
- If no Detective available, Commander may seek aid from another agency.
- Callback protocol:
- Officer consults Supervisor ➜ Shift Commander ➜ (if off-duty) Detective Commander/designee decides if response warranted.
- Detective selection factors: seriousness, required specialization, solvability indicators, patrol resources, scene needs, geography, duty hours, caseload, interview volume, extensive canvass/composite needs, serial-crime leads, arrests in progress, etc.
- Specialized crime-scene services available:
- Latent prints & touch DNA recovery.
- Photography & scene sketching.
- Evidence collection/preservation.
- Crash investigation.
- All evidence transfers require documented chain-of-custody reports.
Case Screening System
Screening Roles
- Shift Commander (or designee): reviews every preliminary report, decides to:
- Forward to Detective Division.
- Retain with Patrol for follow-up.
- Suspend with no further action.
- Patrol officers must not promise Detective assignment unless confirmed.
Solvability-Factor Model
- Each report is scored; if total <7 → usually suspend (unless exceptional).
- Weighted factors:
- Suspect arrested – 10
- Suspect known/named – 10
- Suspect locatable – 7
- Usable touch DNA/fingerprints – 7
- Suspect described – 6
- Reliable witness(es) – 5
- Vehicle registration known – 5
- Vehicle described – 3
- Evidence recovered – 1
- Traceable property – 1
- Time-range of occurrence:
- <1 hr – 5
- 1–12 hr – 2
- 12–24 hr – 1
- >24 hr – 0
Assignment Logic
- Patrol retains most investigations; Detective becomes principal on assigned cases.
- Considerations: seriousness, solvability score, workload, specialized skills.
- Disputes: Detective Commander ↔ Shift Commander ➜ escalated to Captain & Deputy Chief.
- Exceptional follow-up allowed despite low score for:
- Community importance (hate crimes, cemetery desecration).
- Serial/crime-linkage (series burglaries).
- Management exception (high-media or high-risk cases).
- Investigative exception (MO intuition, intel links).
Case Status Definitions
- Open: active, assigned.
- Suspended: all leads exhausted; supervisor approval required.
- Closed: satisfactorily concluded.
Suspending vs. Closing
- Closed when: arrest made; warrant obtained; offense disproved or in another jurisdiction; victim/prosecutor decline; extradition denied.
- Suspended when: awaiting forensics/judicial matters; workload triage; property recovered; no leads or leads exhausted. May reopen on new info.
Case-File Management (IMC/RMS)
- Detective Commander ensures each entry logs:
- Complaint #, case type, assigned investigator, date, solvability & exceptional factors, original officer.
- Review cadence:
- Every workday: files ≥10 days old checked for follow-up reports.
- Goals: victim contacted within 10 days, updates every 10 days, closure target 30 days (subject to complexity), reassess solvability changes.
- Detective submits final supplement upon closure; Records Division retains originals.
- Working copies kept by detective for reference/re-opening.
Contents of a Major Case File
- Original & supplemental reports, written statements, custody forms, lab & autopsy reports, photographs, warrants/returns, impound sheets, miscellaneous supporting docs.
- No originals kept in working file; originals go to Records Room.
Access Control
- Need-to-know basis: Chief, Deputy Chief, Captain/Patrol Commander, Detective Commander, assigned personnel, authorized external agencies.
- All others require express permission.
Purging / Archiving
- Upon final disposition:
- Arrest made ➜ move file to Records; if other suspects remain, detective keeps copy.
- Warrant only ➜ copy of signed affidavit to Warrant File.
- Suspended ➜ keep working copy ≥3 months in Detective Folder then archive at Commander’s discretion.
Accountability for Investigations
Preliminary Investigation Responsibility
- Normally the initially dispatched patrol officer until:
- Case solved; all leads exhausted; supervisor reassigns; or forwarded to Detectives.
- Assistance from others does not remove original officer’s accountability.
Follow-Up Assignment Determinants
- Crime seriousness; skill sets; effort scope (travel, canvasses, witness volume); workload; solvability.
- End-of-shift decisions: Shift Commander decides postpone vs. hand-off.
- Each contributing officer files supplemental reports in IMC/RMS (supervisor approved).
- Patrol Shift Commanders review Detective-returned cases for continued follow-up & reporting.
Standard Cases Forwarded to Detectives
- All felonies impractical for Patrol.
- Misdemeanors requiring out-of-town work or protracted resources.
Shift Commander Core Duties
- Verify completeness of prelim investigation & rapid scene security.
- Approve/return initial & supplemental reports.
- Decide Patrol vs. Detective follow-up; solicit Detectives or other specialized units (Dive-Rescue, Collision Reconstruction, K-9) as needed.
Victim Status Notifications (When Feasible)
- Change of investigator or agency.
- Suspect arrest/referral.
- Suspension of investigation.
Habitual & Serious Offender Program
- Definitions tied to C.G.S. §53a-40 (persistent offender statutes).
- Investigators must:
- Identify, verify, document qualifying offenders.
- Notify prosecuting attorneys whenever such cases approach court disposition.
Practical & Ethical Implications
- Implements equitable allocation of investigative resources via solvability scoring, balancing due-process rights with community expectations.
- Protects evidence integrity (chain-of-custody, secure case-file access).
- Emphasizes victim communication and transparency.
- Aligns with POSTC accreditation standards 1.2.1, 1.2.6, 1.7.6, 3.2.1, 3.4.3 ensuring statewide professional consistency.
Real-World Relevance / Integration
- Mirrors best practices in modern law-enforcement: on-call detective models, evidence-based solvability triage, IMC/RMS electronic case-management.
- Establishes proactive collaboration with prosecutors for habitual-offender enhancements, bolstering community safety.
- Provides scalable framework adaptable to mutual-aid, regional task-forces, and multi-agency critical incidents.
