Probably stupid question: Why not just exchange it to zcash or monero or some other coin that hides transaction details? Then you can send it to a new wallet; theoretically 100% untraceably.

They did that apparently, it is mentioned in the article. There are still ways to trace it. For example, if they do it in a short timeframe or in just two transactions you can match the amounts. Not many people send 100k$ in zCash around.
