Understanding the Information Timeline
Who knows what and when?

Journalists
Bystanders
Emergency responders
Court processes
Researchers
Some information (e.g. social media) can be read immediately, while other information
(e.g. records from the Delaware County Medical Examiner) isn't necessarily available to readers until later.
Check Gun Violence Archive for links to news coverage about the incident
Gun Violence Archive: gunviolencearchive.org
Example incident profile:
https://www.gunviolencearchive.org/incident/1857434
- Provides some information about incident and people involved
- Links to news articles and coverage
- This incident has multiple sources listed, which won't necessarily be the case for other incidents.
This resource can be so helpful that there's a field for Gun Violence Archive (GVA) record links in the incidents spreadsheet.
Unfortunately it's easy to get a false negative when searching GVA - i.e. to think there's no record when there actually is one.
How to look up an incident using
Gun Violence Archive:
- From the homepage, go to
Search Database (top right) - Choose Add a Rule
- Under Most Popular Filters, choose Location
- In the first blank drop-down menu, choose Pennsylvania
- For City, type the city (it should auto-complete). Click Search.
Note: Don't use the County box, it doesn't work!

Examples: Incidents by location (city)
Finding incidents by location and date range

When following links to news stories, you may run into paywalls
There may be news coverage even if there's no Gun Violence Archive record for the incident
-
Delaware County Daily Times
- Example article: "Chester is a model for reducing crime"
- You can read this by using the database Access World News (Newsbank) and searching for the article
- Find the Access World News database link on your course research guide
- Don't see it? Change from "Newest First" to "Relevance"
- Paywalled articles from other newspapers / news sources
- Search Tripod for the newspaper / source (not for the article)
- You can request a PDF using the Journal Article Request link on Borrowing Beyond TriCo
Where else to search for information about incidents
Delaware County & Philadelphia Area News Search
- Linked from course guide with examples
- Limits results to local news sources
- Particularly helpful if you have very little info to use as keywords
- Try searching by date range: "upper darby" after:2021-01-01 before:2022-12-31
- Call records for some emergency response departments in Delco
- Can give you limited basic info about incidents as understood at the time -- remember these early details aren't necessarily accurate
- Ad-supported site run by private individuals, not official
Searching social media
Use existing news coverage to help you choose keywords
Look at existing news coverage of
gun violence incidents:
- Notice patterns – what kind of information is provided? What's missing?
- Pay attention to word choice – what words might come up in news coverage about other incidents?
Some useful keywords found in news articles:
- single words: shot, shooting, killed, homicide, weapon, gun, gunshots
- phrases: "shots fired" "shots were fired"
Each search consists of three main ingredients:
- Sources - which websites or documents you're searching
- Keywords - words you've chosen to include
- Search syntax - instructions you provide to the search engine about how to handle your keywords
Build your search carefully
Let's practice building searches:
Build your search carefully
How to use search syntax:
To find articles mentioning any of these words:
shot OR shooting OR killed OR homicide OR weapon OR gun
Check for multiple keywords at one time using OR
To find articles mentioning any of these words or phrases:
"shots fired" OR "shots were fired" OR shot OR shooting OR killed OR homicide OR weapon OR gun
Example search in Delaware County Times via Access World News database
Build your search carefully
How to use search syntax:
To find articles mentioning Upper Darby and any of the other keywords:
("Upper Darby" AND Pennsylvania) AND (shot OR shooting OR killed OR homicide OR weapon OR gun)
Combine multiple concepts into keyword groups using parentheses ( )
Search by date:
gunshot Chester PA before:2019-12-31 after:2019-10-01
Group and Exclude Terms:
("shots fired" OR gunshot) AND (Chester OR "Delaware County") -"Port Chester" -"West Chester" -"Chester County"
Build your search carefully
How to use search syntax:
Advanced Google syntax
Expand your research toolkit
If you find a broken link, use the Wayback Machine to look for an archived copy.
Search websites for local government, police, etc.
Can help you find press releases and conferences
shooting site:chestercity.com OR site:delcoda.com OR delaware.crimewatchpa.com
Try DuckDuckGo, Bing, or other alternatives to Google
Try searching "police blotter" and town name
If you have an address or building, Google Maps Street View may be helpful for visualizing the location (look for earlier photos)
