Reporters are thorough. Someone’s sex is so obvious they will report he/she. Any good reporter will ask why the police haven’t mentioned someone’s sex.
A decision to not use sexual-based pronouns will be made because the subject of the report identifies as trans.
You are presumably a grown adult who has known this instinctively since childhood.
As a journalist you would ask why are they reluctant to say “she” about someone called Heather. You would not be doing your job properly otherwise.
We can get into the detail if you want but I get bored easily. I’d much prefer to send gifs of kittens.
