Yagura Karatachi

Little is known about this Jinchūriki yet. He hailed from Kirigakure and on the Chapter 420 cover, seemed to be the host of the Three-Tailed Turtle. However, when Deidara and Tobi fought the Three-Tails, Deidara claimed the Bijuu was weak because it had no host. This might possibly be because this Jinchūriki died.

It is suggested that he is a relative of Yukimaru, as they both have similar appeariences. Also, it's been said that Yukimaru can control the Turtle. Whatever connection he may have with this boy, if any, is currently unknown.
