The article title implies that he’s already been sentenced and is on probation. That’s what that string of words means. The probation officer he met with is doing a presentence investigation. They aren’t assigned to him.

I.e. not his probation officer because he’s not on probation because this is still pre-sentencing.

I edited italics for clarity. Don’t be an ass.

Edit I also edited this post for clarity. Twice!
