From previous questions this bitcoin 1FYMZEHnszCHKTBdFZ2DLrUuk3dGwYKQxh address had an invalid public key of "00" and was unspendable but the coins are now spent?? The invalid key was generated by a bug in the wallet software the owner was using and should have been "locked" due to the invalid key

see link to the owners original query https://www.reddit.com/r/Bitcoin/comments/2t3vn0/i_cant_send_my_btc_a_triangle_apear_i_use_multibit/

also see link to a paper that lists that this is an invalid key https://www.microsoft.com/en-us/research/wp-content/uploads/2013/11/734.pdf?from=http%3A%2F%2Fresearch.microsoft.com%2Fpubs%2F204914%2F734.pdf
