Why? They are both identifying details.
His name is more identifying than the scar. If I put his name here, which i could, people could go and look him up. I didn't put gis name here because i realise that it is too identifying.
However, If I write about his scar here, which I did, people can't find him by that information,as it is less identifying.
The people on X who said that the scar could possibly have been caused by Jojo are not just speculating from nowhere.
Some of them are local people who remember this particular man having cuts and scratches on him right after Jojo went missing. So it's relevant.
