I’m going to echo the suggestion to approach men (and later women) for whatever reason to practice approaching people you don’t “have business” with.
Ask a question, comment on something benign (cool shirt?), etc.
And also expand your list of contexts where it’s ok to talk to people.
Anywhere that groups of people gather is a good option. Concerts, cafés potentially, parks…as long as you aren’t cornering anybody, you should be fine.
I’m not investigating those bullet points. First thing I’m doing is trying to get help for myself, and getting “help”/police for the dead person. And also a lawyer for myself.
Getting help for myself includes contacting people at home, confirming the timeline and alibi.
