I know for certain you can track which miner mines the block and what time this happened, but Is it even possible for a miner to return such a good reward??
As far as am concerned miners look forward to harvesting such block rewards because they know that these mistakes always happen & will not stop today either and you can not blame anybody for such a costly mistake, besides why bother with the fees when 9 out of 10 times the fees suggested by the wallet app will usually be adequate enough for you not to wait all day for a single confirmation

Whatever is happening here, this guy has learnt the hardway!
