After reading only the headline, I for one assumed it was the official's child, so it's at least somewhat misleading, perhaps not intentionally though.
At least personally, I generally don't assume son or daughter imply age. It's just the relationship. Here's an example headline where the son was almost 100 years old[1]:
> JRR Tolkien's son Christopher dies aged 95
