SMH, must be a Kalifornia millennial wanting someone else to do their work for them so they can take credit and get paid.
First off you'd need to provide some more information that just a date. The approximate time in UTC or at the very least an approximate local time is a must have piece of information. Second, you're talking about some of the most highly controlled, and so hardest to search through, sectors of airspace in the US. So even if you have a good idea of what time the event occurred, there is little guarantee that it is a feed covered by LiveATC. If you have a tail number for the aircraft then sometimes more information from other sources can be looked at to try to narrow down the search as well. Being that this is apparently something that was covered by some news crew, a link to their story might also be somewhere that someone here could get additional details as well. I don't know if this is your first assignment for CBS in San Diego, or you just have no clue of how aviation and aviation audio works, but in the future these are some things to keep in mind when requesting audio here.
