Motorcycle chase breakdown in communications

[CharlesDom]

Just a little while ago (about 10:05 PM) Baldwin Park police started chasing a motorcycle, soon afterwards Air 45 joined.

It went from the 605 Frwy to the 210 Frwy East all the way into Rancho Cucamonga. As the units neared RC, Air 45 and Baldwin Park PD (2 ground units) couldn't communicate with each other and dispatch couldn't hear the ground units either but dispatch could hear Air 45 clearly.

My question is; why couldn't Air 45 and the BP ground units hear each other, they were in the same area.

Dispatch had to relay Air 45 comms to Rancho's dispatch then to ground units. Yeah I know, really weird.

There was a brief ground search after the suspect ditched his motorcycle and tried to run away on foot. That's where the problems came in; the air unit kept up with the suspect but had problems relaying to the info to the ground units. They couldn't hear him.

Also I wonder why BP was cleared to travel so far out of their area when they could have easily had CHP take over, they were on the freeway most of the time until the pursuit reached Rancho.

I've never heard such a scenario before. But in the end they caught the suspect, he only had a brief getaway.

Interesting. The only thing I can comment on is CHP- they don't like getting involved in other departments pursuits. They're extremely consious of the liability, and public image. There was a pursuit here in sac county earlier this week. CHP would not take over the pursuit.... Sac chased the guy way out of their juristiction then cancelled the chase. CHP picked the chase again after a half hour or so after it was relayed the guy was going to prison the next day and was leaving the state.

Baldwin Park uses repeaters and the ground units probably weren't getting into the repeater. If the ground units aren't getting into the repeater, nobody will be able to hear them. As far as BP dispatch needing to relay the helicopter traffic to RC dispatch it sounds like the helicopter didn't have or didn't switch to the RC channel.

Interoperability or the lack their of! As far as BP and RC two different radio systems. You BPPD on a UHF system and RCPD on 800 trunk system. BP could hear Air 45 still due to line of site but I am curious to why the ground units couldn't communicate unless they don't have the ability to go to direct.
One of the two dispatches should've found a common law channel and patched into it but for some reason a lot of dispatches don't due this.
It's not unusual for PD/SO to go out of their AOR, I think a lot comes down to who and why their chasing.
LAPD once chased a suspect from west LA to Barstow but then again this fine department has some screwed up policy regarding chases, that or the WC was hoping he was making a break for Las Vegas.

It's not unusual for a department's radios to be equipped with direct, or talk around channels and mutual aid channels, and the officers have no idea that they're there, or the radio programming is so complicated that it's not easy to get while driving in a pursuit. I even know of one department that states 'thou shalt not change channels without an LT's approval'.

I realize im a bit late responding to this, but I do have the audio from that chase that I recorded myself, I have edited out all the nonsense stuff and I also included the audio from Azusa PD's freq (when the guy exited the 210 for that brief moment) Heres the link:

This video reminds me of the female car chase in Santa Cruz last Saturday. They chased her all the way to Redwood City and back. The CHP joined the pursuit, when the suspect hit highway 17. The change from green to the ruby channel was seamless once they hit the county line...

Know if anyone captured the audio of the chase? Sounds like a good listen...

I don't don't know about the BP incident, but that You Tube video is crazy. It's hard to tell if that woman was drunk, insane or maybe both...
