Yes. I wonder if it's possible that when police found the car, then spoke to his family, something such as "if we could see his banking information it might show where he is, like purchases" and the 3rd party accessed the information and then it was all down hill from there and ST was declared missing?
I only wonder this because my ex husband and I were on good terms after separating. Even though we had no joint financials, he gave me the Internet details for his banking for various reasons. He had quite bad MH issues at times and if we hadn't heard from him for a few days, I could see by his bank where he'd been/what he'd been buying recently (hoping of course it was always him using the card!). He went on benders at times. The last time we hadn't heard from him for a few days, I could not see any activity on his bank account and went to police. He was located deceased later that day with no suspicious circumstances. So, not saying his folks checked his bank all the time, but may have had his details and used them prior to the bank being advised ST was missing.
I think in early reports LE indicated ST hadn't used his bank or accessed SM, so perhaps they just got the necessary documents to access his accounts very quickly.
