The painter's case is one of the few exceptional cases we've seen about accidental Bitcoin hodlers who profited. There are cases of those who lost their wallets or couldn't remember where they kept their seedphrases or PKey and as such lost every access to their wealth. However, why would the painter still want to locate the man who sent her the Bitcoin is what doesn't make sense to me. She ought to silently and quietly bask in the euphoria of her new found wealth and not expose herself.
