Chiyo was a retired Sunagakure(Village hidden in the sand) elder who was grandmother of Sasori.
It was the combination of Sakura and Chiyo (his grandmother)
He gets into a fight with his grandmother (lady Chiyo) and Sakura and they both kill him.
He and Deidara had captured Gaara and Akatsuki had extracted Shukaku from him, hours later Sakura and Chiyo (His grandmother) arrived and began to fight him. Sakura was being controlled by chakra strings so Chiyo was using her like a puppet. After long hours of fighting Chiyo finally strikes Sasori on his heart using the first human puppets Sasori himself had created. (His parents.) Apparently he let his grandmother kill him. He then says some stuff about Orochimaru and dies.
Besides Itachi having sasuke as a little brother there are no relatives shown in naruto to any other akatsuki mebers except for sasori they have his grandmother and his cousin(gaara IS sasoris cousin belive or not!)
He never does. Chiyo Basama does. If u've seen the lastest few episodes of SHippuuden or u've read the chapter a couple years ago, u'll see Gaara's grandma tells her. Chiyo-baasama is not Gaara's grandmother.
His ring says: 玉 (Sphere)
