What time of day was this?
What did he look like, other than black? Attire, etc.
You knew he was walking behind you. Did you look over your shoulder multiple times?
Relatively clean shaven, clothes worn but clean. Brown jacket, shirt, jeans and boots. No slur in his speech. Firm hand shake and looked me in the eyes. Normal dude, probably going home from work. About 5’10 and probably 175.
I looked at him when I was walking my coworker to her car as he came from an area I didn’t expect. That’s it. Then I walked down the sidewalk maybe 30 feet to the bus stop. Then I stepped to the back edge so he wouldn’t have to walk around me.
