🔍 MODULE 2: RESEARCH METHODOLOGIES
Systematic Approaches to Information Gathering

LESSON 2.1: Planning Your Research Strategy
Duration: 1 hour | Prerequisites: Module 1 completed

Learning Objectives
  • Develop comprehensive research plans for investigations
  • Identify appropriate sources for different types of information
  • Create systematic documentation systems
  • Apply the "research funnel" approach effectively
The Research Planning Framework

STEP 1: DEFINE YOUR RESEARCH QUESTIONS

Start every investigation by clearly defining what you need to learn:

Primary Questions
- The main mysteries you're trying to solve
  • Who was involved in the incident?
  • What exactly happened?
  • When did events occur?
  • Where did events take place?
  • Why did events unfold this way?
  • How did events happen?
Secondary Questions
- Supporting information that helps answer primary questions
  • What was the person's normal routine?
  • Who were their close associates?
  • What stressors were present in their life?
  • What resources did they have available?
  • What similar cases have occurred?
Research Question Hierarchy Example:

STEP 2: SOURCE IDENTIFICATION AND PRIORITIZATION

Primary Sources (Highest Priority)

  • Official records and documents
  • Direct witness accounts
  • Contemporary news coverage
  • Physical evidence and forensic reports
  • Official statements from authorities
Secondary Sources (Medium Priority)
  • Expert analysis and commentary
  • Academic research on similar cases
  • Historical context and background information
  • Comparative case studies
  • Professional opinions and assessments
Tertiary Sources (Lower Priority)
  • General reference materials
  • Popular media coverage
  • Social media discussions
  • Rumors and unverified claims
PRIMARY: What happened to Sarah Martinez on March 15, 2019?

SECONDARY:

  • Fridays?- What was Sarah's normal routine on Fridays?
  • regularly?- Who did Sarah interact with regularly?
  • life?- Were there any recent changes in her life?
  • disappearance?- What was her emotional state in weeks before disappearance?
  • area?- Are there similar cases in the area?

TERTIARY:
  • 2019?- What was the weather on March 15, 2019?
  • day?- What events were happening in the city that day?
  • available?- What transportation options were available?
  • routes?- What businesses were open along her usual routes?
  • Speculation and theories

The Research Funnel Approach

WIDE TOP: Cast a Broad Net Initially

  • Start with general information gathering
  • Explore multiple angles and possibilities
  • Don't narrow focus too quickly
  • Collect more information than you think you need
  • Stay open to unexpected discoveries
NARROW MIDDLE: Focus on Promising Leads
  • Identify patterns and connections in broad data
  • Pursue the most promising lines of inquiry
  • Verify key facts through multiple sources
  • Eliminate dead ends and false leads
  • Concentrate resources on high-value research
SHARP POINT: Deep Dive into Specific Areas
  • Conduct intensive research on confirmed leads
  • Gather detailed information about key elements
  • Cross-reference findings extensively
  • Build comprehensive understanding of focused areas
  • Prepare for evidence analysis and conclusion drawing

Documentation and Organization Systems

The DOCS Method:

  • Document everything as you find it
  • Organize information systematically
  • Cite sources completely and accurately
  • Search your files regularly for connections

Essential Documentation Elements:
1.Source Information​
- Where did you find this information?​
2.Date and Time​
- When did you discover/record this?​
3.Reliability Assessment​
- How trustworthy is this source?​
4.Context​
- What circumstances surround this information?​
5.Connections​
- How does this relate to other findings?​
6.Follow-up Actions​
- What additional research is needed?​

LESSON 2.2: Advanced Search Techniques
Duration: 90 minutes | Prerequisites: Lesson 2.1

Learning Objectives
  • Master advanced search operators and techniques
  • Navigate complex databases effectively
  • Develop specialized search strategies for investigations
  • Apply cross-referencing and verification methods
Search Engine Mastery
Google Advanced Search Operators

Basic Operators:

"exact phrase" - Find exact word combinations
site:websitessite:example.com - Search within specific websites
filetype:typesfiletype:pdf - Find specific file types
intitle:"titleintitle:"search term" - Find pages with term in title
intext:"contentintext:"exact phrase" - Find exact phrase in page content

Advanced Operators:
related:websitesrelated:website.com - Find similar websites
cache:pagecache:website.com - View cached version of page
define:explanationsdefine:term - Get definitions and explanations
stocks:informationstocks:AAPL - Get stock information
weather:informationweather:city name - Get weather information

Date and Number Operators:
after:dateafter:2020 - Content published after specific date
before:datebefore:2015 - Content published before specific date
2010..range2010..2020 - Content from date range
$products$100..$500 - Price ranges for products

Wildcard and Exclusion:
* from")* - Wildcard for unknown words ("* disappeared from")
- dogs)- - Exclude terms (cats -dogs)
OR - Either term (missing OR disappeared)
() 2019)() - Group terms ((missing OR disappeared) AND 2019)

Investigation-Specific Google Searches:
Finding People:

"John Smith" + obituary + "died 2020"
"Jane Doe" + (LinkedIn OR Facebook OR Twitter)
"Robert Johnson" + address + phone + city
"Mary Williams" + (graduated OR alumnus) + university

Finding Events:
"March 15 2019" + accident + highway + city
crime + robbery + "convenience store" + date + location
missing + person + name + last + seen + date

Finding Documents:
filetype:pdf + court + records + name
filetype:doc + police + report + case
site:gov + missing + person + database
site:newspapers.com + obituary + name + date

Database Navigation Strategies

Public Records Databases:

  • Ancestry.com Research Techniques:
  • Start with exact name and approximate birth year
  • Use wildcard searches for uncertain spellings
  • Cross-reference family members to verify identity
  • Use location filters to narrow results
  • Check multiple record types (census, vital records, directories)

    FamilySearch.org Optimization:
  • Use "Historical Records" for official documents
  • Try alternate spellings and phonetic matches
  • Search by location when names are common
  • Use date ranges rather than exact dates
  • Explore community-contributed information carefully
Newspapers.com Advanced Search:
  • Use quotation marks for exact phrases
  • Combine person's name with location terms
  • Search by date ranges around known events
  • Use "Browse by Location" for local coverage
  • Check multiple newspaper titles in same area

Government Database Strategies:
Federal Resources:

  • PACER (pacer.uscourts.gov) - Federal court records
  • SEC EDGAR - Corporate filings and reports
  • USPTO - Patent and trademark searches
  • Library of Congress - Historical documents and photos
  • National Archives - Government records and documents
State and Local Resources:
  • Secretary of State websites - Business registrations
  • County Clerk offices - Property and court records
  • Vital Records offices - Birth, death, marriage records
  • Professional Licensing boards - License verification
  • Sex Offender Registries - Criminal background information
Cross-Referencing and Verification

The Three-Source Rule:

  • Never rely on a single source for important facts
  • Seek independent confirmation from multiple sources
  • Note when sources cite each other (not truly independent)
  • Document source reliability and potential biases
  • Flag information that can't be verified

  • Source Triangulation Method:

    Fact to Verify: John Smith lived at 123 Main Street in 1995
    Source 1: City directory listing (official record)
    Source 2: Voter registration (government database)
    Source 3: Utility company records (business record)
    Verification Level: HIGH (three independent official sources)


Red Flags for Unreliable Information:
  • Information appears on only one website
  • Source has obvious bias or agenda
  • Details seem too convenient or perfectly aligned
  • Anonymous sources with no verification possible
  • Information contradicts multiple reliable sources
  • Source has history of inaccuracy
Specialized Investigation Searches
Missing Person Research:
Fact 1995
Search String Examples: "2020)"
Jane Doe" + missing + disappeared + (2019 OR 2020)
John Smith" + found + identified + remains + DNA
missing + person + name + reward + family + contact
Mary Johnson" + sighting + alive + spotted + seen

Criminal Case Research:
Search String Examples:​
"court"Robert Jones" + arrested + charged + convicted + court​
case recordscase + number + "12-CR-345" + defendant + records​
"report"Sarah Wilson" + victim + crime + police + report​
suspect trialsuspect + description + witness + testimony + trial​

Historical Research:
