Yep just as the title says Sarutobi Asuma died on thursday due to a metal spike piercing through Hidan's chest ( Hidan is an akatsuki Member). Hidan uses this jutsu called Kami no Sabaki - God's Judgment. Kami no Sabaki is a Ninjutsu technique used by Akatsuki member Hidan. This unique jutsu allows Hidan to inflict whatever damage his body takes onto his opponent. Hidan will first form a Jashin symbol on the ground. This religious symbol of an evil god cult is tied into his belief system. Hidan will next draw blood from his opponent; the usage of his ranged scythe will help in this step. He will then consume the blood of his opponent to begin the ceremony.

With the blood consumed his body will darken and form a skeletal deaths head outline on his body. Then by placing himself within the circle of the symbol, any damage he takes while within it will also be felt by the opponent whose blood he consumed. Hidan will use a pike to cause self-inflicted damage which transfers to his opponent. If he steps out of the circle, the connection ends and his opponent can damage him with no ill effects on themselves. Note that this technique does not appear to be tied to Hidan's general ability to not die. Keeping with his strict religious nature, if Hidan wins his battle he will finish out the technique with a thirty minute long prayer ceremony by laying on the symbol with the pike through his chest. With this process his body will lose its skeletal outline and it will regain its natural appearance. Asuma fought Hidan with the help of shikamaru, Kotetsu, and Izumo. They managed to get Hidan out of his Jashin symbol and cut his head off. But Hidan was still alive and with the help of his partner Kakuzu he got his head sewn back on. He then went back into his Jashin symbol and since he had consumed some of Asuma's blood he was able to pierce his own chest making Asuma feel the effects too. Then Ino and Choji came to his rescue, Ino tried to heal him but his internal organs were damaged so there was nothing she could do(since she wasn't as skilled in medical jutsu as sakura). Asuma died moments later.
