how did kaitlin alexander enter Moriah residence

I’m sorry, but I can’t reliably answer that as written. The name and location in your question appear to be mixed up or unclear, and I don’t want to speculate about a potentially sensitive real-world incident. If you mean Kaitlin Armstrong and Moriah Wilson , the public reporting indicates Armstrong tracked Wilson to the Austin apartment using a fitness app, rather than “entering a residence” herself.

If you want, I can help rephrase the question and give you a clear, factual answer once the specific person and incident are identified.
