Help with stolen or lost 4.4 BTC. Old Jaxx wallet/phrase brought into Exodus wallet, funds show up then disappear. Details inside, please help.

Need help understanding what happened with a user. They had an old Jaxx wallet they originally setup that had the 12 word phrase. Since Jaxx isn't around they tried Atomic wallet first but atomic only showed $2k worth, so they tried Exodus where all 4.4 btc showed up. Within minutes a transaction happened moving all 4.4btc.

Is this a Jaxx recovery wallet issue or are the funds gone? It was on his iPhone. FBI has been reached out to.

Any help or guidance is appreciated!
