Any help would be appricatted as I feel this is a safety concerns as well as harassment and or disturbing ones peace.
Nothing you can do. As others have said, welcome to the CB wasteland. As soon as you "fix" this issue, another will pop up.
FCC isn't going to do anything. Getting them to enforce licensed services like GMRS, amateur, broadcast, etc. is hard enough. They've all but given up on CB.
But, if you really want to try, you'll have to do all the hard work for them. That will mean positively identifying the street address of the transmitter. Recording proof of it being dead keyed on purpose. Write it all up and present it to the FCC.
And then wait.
And wait some more.
Keep waiting.
You are not even close.
Maybe in a year or two, when the FCC has nothing better to do, has a full budget and they are really bored, they'll look at it.
If they can identify the source, they'll send a letter of admonishment.
Then you wait some more.
Keep waiting.
Yep, you guessed it, keep waiting.
Maybe the FCC will administer a slightly harsher worded admonishment.
Repeat wait cycles. Again, maybe in a year or two they'd actually send out a NAL with a fine.
I'm sure by that time the guy with the offending CB will get bored, his radio will break, his antenna will fall down, his power supply will burn out, etc.
So, basically a lot of work and a lot of waiting.
The FCC doesn't troll around now in trucks looking for people to bust, they don't have the staff. They wait for complaints. Trust me, they have MUCH higher priority issues to deal with that CB. CB is down there with the Mickey Mouse FRS radios, maybe a bit higher, but not much. The FCC washed their hands of the CB wasteland a long time ago. You'd be hard pressed to find much in the way of records of actual enforcement on the CB band. Maybe one or two for guys running thousands of watts, but not guys dead keying.
And the "safety concern"? Come on, seriously, it's CB. You cannot claim a safety hazard on a license by rule system that the FCC gave up on years ago. Especially, when as stated above, there are 39 other channels to use.
"disturbing the peace"? CB and Peace are not two things I'd ever put together. If it's disturbing your peace, then it's time to turn your radio off. Seriously. Trying to claim this is a serious legal matter is taking this a bit to far. Not trying to jump on your case, but lets keep this in perspective here. Hobby radio, 4 watts, 39 other channels, no licenses, consumer grade radios, grown adults acting like children?
"Harassment"? Unless it is directed at you, you're not going to be able to prove this is harassment. It might be annoying, but it isn't harassment.
FCC doesn't care. This is low priority. Local PD/SO has got bigger issues to deal with.
If you are really into radio that much and nonsense like this gets your feathers ruffled, you need to step away from CB and work on getting a more suitable license. The nut-jobs that play these games on CB will eat you alive and crap you out. They are not scared of the FCC, they know the local PD isn't going to waste their time on this, and they know they can annoy other people by doing this. That's where they get off on this, knowing they've annoyed someone else. It isn't worth the fight.
And....
Are you 100% sure this is a deliberate dead key? Or is it just interference from some other source? Unless you can track this down to an actual CB radio with the key taped down, the FCC is probably going to ignore it. There are way too many other sources of interference on CB. Cheap radios alone will be a source of interference. Modern electronics can all cause issues, WiFi, routers, etc. etc. etc.
Rumors of CB'ers duking it out on the streets about who's the "channel king" may have been something in the 70's, but I'd find it hard to believe that it's something that really happened recently. Usually stupid stunts like that have been relegated to internet chat boards, radio forums, etc.
