Former Coworker Filmed Me, Was Fired, And Now I’m Getting Racist Notes/messages. What Can I Actually Do?

Hi, I’m in Texas and honestly just trying to understand what options I have at this point because this seems to just be escalating and i feel like im not getting the help i need.

I posted previously in another sub, but things have escalated and people suggested I come here?

To summarize...I work full-time from home and part-time at a school. A coworker at said partime job (who on reddit ive been calling Casey) secretly took videos of me outside of work to try to “prove” I was faking a disability.

I reported this to HR first. Legal eventually got involved. She was put on an admin break, then moved to a different office, and as of this week I was told she’s been finally terminated. She has a relative (her stepfather) who works 2nd tier only to our Director, and he's also reached out to apologize stating that she is struggling financially and is a hard worker and thus was very stressed about getting a better paying position. I can copy and paste it below if needed.

There were snow days during part of this (Texas winter storms), so there was a gap where no one was on campus. I was told this delayed me from even logging on to my company email and seeing this info.

What’s happening now is that since she was fired, some really unsettling things have started around the same time. For example on Tuesday the 27th, I found a handwritten note placed on my car while it was parked outside my home. It included a racial slur (“n-b*tch”) and calling em selfish. I quickly checked with neighbors on either side and I was the only one who got a note. I checked my dash cam and moved a camera on my home to cover the area going forward. The footage from my dash only shows someone bundled up approaching the car, but no identifying details. As their face was covered and they were wearing like ski looking goggles.

Wednesday night the 28th,, I went to trivia night with a friend who drove us in her vehicle (she had "snow tires" on her vehicle and though the roads in our area were pretty clear we wanted to be cautious). When we came back to her car, there was another note with similar language left on her car! We went back and asked for footage but they said they didn't have cameras that worked out there. No damage to either car and we did double check during daylight just in case.

I’ve also started getting texts from unknown numbers beginning Monday that are hateful or at least pretty scary. I haven’t replied to any of them. I’ve muted the numbers (in case they text again) and saved screenshots for the police...I reported both note incidents and the messages. I was told that filming in public isn’t illegal..leaving a note without damaging property isn’t a crime, and the messages aren’t "actionable" unless they escalate???

They did take reports and told me to keep documenting which I fully intend to do.

Casey no longer works for the company. HR/legal are aware of the original situation. I’m documenting everything (dates, screenshots, photos). I have cameras and a dash cam. I’m not fully changing my routines, but I am being cautious.

I think that's pretty much everything...but ask me questions if needed and I will answer. So my questions are:

1. At what point does this become harassment or stalking under Texas law?
2. Is there anything proactive I should be doing now besides documenting?
3. Would a cease and desist make sense, or could that backfire?
4. Is there any civil option here, or is this realistically just “wait and see unless it escalates”?

I’m not trying to overreact...but the pattern is starting to freak me out and I want to make sure I’m handling this the right way and get the help I need to make this stop. I am almost certain it's Casey but without proof I'm not able to get any traction with the cops.

Thanks in advance
