| One day, a man who had perhaps a 5th dan in judo came to the dojo, and Yukawa was told to practice with him. |
| He may also have been the murderer of Japanese hostages Haruna Yukawa and Kenji Goto. |
| Goto went missing in October in Syria, apparently while trying to rescue Haruka Yukawa, 42, a private military company operator, who was abducted by the militants in August. |
| And last month, the militant appeared in a video with the Japanese hostages Haruna Yukawa and Kenji Goto, shortly before they were killed. |
