I suspect she was in a place she wasn't suppose to be, where crimes were happening or had happened and she bolted when the cops came. They asked her (him?) to stay put but she didn't or she was seen leaving the area and they apprehended her for fleeing but had no evidence of her committing an actual crime.
Yes -
" Sec. 38.04. EVADING ARREST OR DETENTION. (a) A person commits an offense if he intentionally flees from a person he knows is a peace officer or federal special investigator attempting lawfully to arrest or detain him.

She has a history for that charge, so it could fall under any of those things, except 3, because there would be at least some reporting on that.
