Managing Multiple Callers
The First Call
Managing Multiple Callers
L
Brief
Active shooter incidents may generate several 911 calls within seconds.
Some callers may be hiding. Some may be running. Some may be injured. Others may be calling from outside the scene, reporting what they heard or saw.
Your challenge is to gather critical information without becoming overwhelmed by the volume of calls.
Why Multiple Callers Matter
No single caller usually has the full picture.
One caller may know where the suspect entered. Another may know where victims are located. Another may see the suspect leaving. Another may report a suspicious bag, vehicle, or second suspect.
Together, multiple callers help dispatch build the operational picture.
What Multiple Callers May Report
- Shots fired
- Suspect location
- Suspect description
- Weapon information
- Victim locations
- People hiding
- Evacuation routes
- Secondary entrances or exits
- Suspicious bags or vehicles
- Conflicting suspect descriptions
- Rumors or social media information
Dispatcher Tip
Multiple callers do not create confusion when information is organized.
Separate what is confirmed, reported, unconfirmed, duplicated, and urgent.
Caller Priority Types
Caller Inside the Threat Area
This caller may provide the most immediate information about suspect location, movement, weapons, victims, and hiding locations.
Priority: High
Caller Who Can See the Suspect
This caller may provide suspect description, direction of travel, weapon information, clothing, bags, or vehicle details.
Priority: High
Caller Outside the Location
This caller may provide information about evacuation, exits, parking areas, suspect vehicles, or crowd movement.
Priority: Moderate to High depending on information
Caller Reporting Social Media Information
This caller may not have firsthand information. The report should be documented and verified through agency procedures.
Priority: Depends on content and urgency
Duplicate Caller
This caller may repeat information already received, but may still provide a new detail.
Priority: Screen quickly for new critical information
The First Question for Multiple Callers
When multiple calls are coming in, the first question should quickly determine whether the caller has direct, useful information.
“Are you there now, and can you see or hear what is happening?”
This helps separate direct witnesses from callers reporting secondhand information.
Information Sorting
During multiple-caller incidents, dispatchers should mentally sort information into categories:
| Category | Examples |
|---|---|
| Critical | Shots being fired, suspect location, victims injured, officer safety threats |
| Important | Suspect clothing, vehicle description, direction of travel, caller location |
| Unconfirmed | Possible second suspect, social media reports, conflicting descriptions |
| Duplicate | Repeated reports already documented, unless a new detail is provided |
Conflicting Information
Multiple callers may give different information. This does not always mean someone is wrong.
Callers may be seeing the suspect from different angles, at different times, in different lighting, or from different locations.
A suspect may also remove clothing, change direction, enter another area, or be confused with fleeing civilians or plain-clothes responders.
“Multiple descriptions being reported. One caller reports black hoodie; another reports gray jacket. Second description unconfirmed.”
Dispatcher Tip
Do not discard conflicting information too early.
Label it clearly, document it, and allow responders to verify.
Managing Caller Flow
During a surge of calls, agencies may use different procedures depending on staffing, technology, and policy.
General best practices include:
- Keep direct witnesses on the line when possible.
- Quickly screen duplicate callers for new critical information.
- Document caller location and relationship to the incident.
- Relay life-safety information immediately.
- Identify unconfirmed information clearly.
- Coordinate with other dispatchers to prevent duplicated or missed information.
- Use CAD notes consistently and clearly.
What to Ask a New Caller Quickly
If calls are stacking, use a fast triage approach:
- Are you at the location now?
- Can you see or hear the suspect?
- Where exactly are you?
- Where is the suspect now?
- Are people injured where you are?
- Do you see a weapon, bag, or vehicle?
- Is this firsthand information or something someone told you?
Key Dispatcher Takeaway
Multiple callers can overwhelm a communications center, but they also provide the pieces needed to build the operational picture.
Your job is to identify which callers have direct, urgent, life-safety information and to make sure that information reaches responders quickly.
Multiple calls are not just noise. They are data.
