I suppose you mean this:
{
          "amount": {
            "amount": "38611393904",
            "asset_id": "1.3.0"
          },
          "extensions": [],
          "fee": {
            "amount": 47737,
            "asset_id": "1.3.0"
          },
          "from": "1.2.90162",
          "memo": {
            "from": "BTS8BbZqGbPVjHkYtswX92QbJwgAKovnwkRddW4Qq3zvyLYWKCD88",
            "message": "aec3266640276c866e87de1a891441c6",
            "nonce": "401396210379214",
            "to": "BTS7N3Y2ozxLvnRk5z2bQXHoTY431aLnizi1KhjcU1CreYtXrZM8C"
          },
          "to": "1.2.444403"
        }
"BTS7N3Y2ozxLvnRk5z2bQXHoTY431aLnizi1KhjcU1CreYtXrZM8C" is the memo key of the recipient. The recipient *account* has ID "1.2.444403", the sending account has ID "1.2.90162".
It seems that the explorer is out of sync. Other explorers show the transaction, e. g. 
https://bitsharescan.com/account/joeboomofo, and it's also in your account history on 
https://wallet.bitshares.org/#/account/joeboomofo .
