11/2005 An off duty motor officer with the Coronado Police Department become involved in an accident on the freeway in the city of San Diego. The motor officer was on his way home on the freeway when another motorist cut him off causing the officer to collide with the other vehicle. The officer was able to put out the accident on Blue 1 which allowed him to not only contact his dispatcher at Coronado P.D., but to advise the Highway Patrol who heard his transmission and get officers headed his way. A Sheriffs deputy from the Poway Patrol Station who was in the area also heard the transmission on Blue 1 and responded to assist. Because several communications centers and field units were monitoring Blue 1, assistance from several agencies assistance was able to respond and assist the injured officer with no delays.

07/2005 San Diego County Sheriff's deputies from the Encinitas Patrol Station received a report of a stolen big rig that was headed south on Interstate 5 from the Aliso Creek rest stop.  Further investigation revealed the suspect driving the truck was wanted for felony charges in Orange County and had stolen the truck after crashing the vehicle he was originally driving.

Responding units were able to catch up to the stolen big rig and attempted to initiate a traffic stop on the freeway.  The suspect did not yield and deputies pursued.  The pursuit lasted approximately 20 minutes at a high rate of speed with units from various Sheriff's Department, San Diego Police and the California Highway Patrol.  Using mutual aid channels (LE S CMD and BLUE 1), units were able to coordinate with each other, including the attempt in setting up a deployment of spike strips to stop the vehicle.  The pursuit was terminated once the suspect crossed into Mexico.

Deputies from the San Diego Sheriff's Department requested assistance from the San Diego Police Department with a foot pursuit of a suspect in the Imperial Beach area.  To facilitate communications between the two agencies, a console patch was put into place by Sheriff's Communications Center and the San Diego Police Communications Center (RCS/SDP1).  The responding San Diego Police Department officers were able to talk directly to the deputies in a coordinated effort, which resulted in the apprehension of the wanted subject.

03/23/2003 A California Highway Patrol (C.H.P.) unit initiates a traffic stop in the City of Santee.  The driver flees on foot and the officer gives chase, advising his dispatcher. 

The C.H.P. dispatcher requests assistance from the Sheriff's Department.  C.H.P.'s primary dispatch channel is patched with the regional mutual aid talkgroup (LE S CMD) and responding Sheriff's deputies, along with an El Cajon Police K-9 officer, switch to LE S CMD.

10/24/2003

Coronado police officers were dispatched to a burglary in progress onboard several boats in the Coronado Cays area.  Once suspect fled in a vehicle, and was taken into custody shortly thereafter. 

While officers were conducting boat-to-boat searches for the outstanding suspect, they located a suspect hiding in one of the boats.  The suspect had armed himself with 3 flare guns, and was refusing to comply with officers.  The Coronado officers backed away from the boat as the suspect began firing flares toward the officers and surrounding homes.  Coronado requested additional units from SDSO, SDPD K-9’s, and Harbor Police firefighters and divers. 

The suspect started a fire onboard the boat he was hiding in, and finally fled into the water once the boat was fully engulfed.  The suspect hid in the water under the docks, out of reach of the officers and K-9’s. 

In order to maintain coordination of these units, Coronado’s Dispatch 1 was patched to LE S CMD.  For the next two hours, dispatchers and the 24 units on scene were able to communicate effectively, providing clear fields of fire, sufficient resources available where needed, and updates on the suspect’s location.  San Diego Harbor Police divers finally took the suspect into custody.

04/2003

A residential burglary suspect is interrupted by the victim who arrived home in Bonita.  The suspect flees in a vehicle and the owner follows while calling 911.  The victim provided updated location information to the Sheriff's 911 dispatcher as he followed the suspect.  

With the suspect now in the area of San Diego Police Department, a radio patch was done to connect San Diego Police Officers and Sheriff's Deputies.  As officers and deputies were continually updated by the Sheriff's dispatcher on the suspect's location, San Diego police officers caught up to the suspect and initiated a felony traffic stop.  Suspect was taken into custody.

05/22/2001 An 18 year old ex-student armed with a 12 gauge shotgun and a .22 caliber pistol began firing at students and staff at Granite Hills High School in the City of El Cajon.  

An El Cajon Police School Resource Officer assigned to the high school notifies his dispatch and engages the suspect.  A sheriff's deputy, who was at the school conducting an unrelated investigation, also notifies her dispatch and responds to engage the suspect.  Suspect was wounded in a brief gun battle and taken into custody.

Numerous units from the El Cajon Police Department, Sheriff's Department, California Highway Patrol, fire/medical and others responded to the high school.  With the El Cajon Police dispatcher patching their primary talkgroup with the regional command talkgroup (LE S CMD), all agencies involved were able to communicate and work together effectively in crowd control, maintaining a perimeter, tending to wounded persons and searching for any other suspects.
