I believe this is the only unconfirmed input

https://blockchain.info/tx/4c23df09b6d320a9f090e14b704f86cf544d31dee9e8fc8279ccedbae82e222c

As for the tx its not on any other explorer and it never was. It was showing only on blockchain.info (i dont think it got to the mempool)

I am wondering if the tx is still in the system somewhere or he got the btc back and should resend again?
