Who Killed Itachi?

It was a cloudy day. A little gloomy. Tsunade's day was as gloomy as the sky.

Last night, Itachi was killed in a fight. He was in a fight that consisted of: Himself, Deidara, Naruto, And Sasuke.

Each person had an intention to kill him. What needed to be known was who did the deed of killing Uchiha Itachi.

Tsunade already had too much work on her hands so why not get one of Konoha's best minds to figure out the mystery? "Shizune!" Tsunade yelled.

Her assistant rushed with TonTon by her side. "Yes Tsunade-sama?" Tsunade then explained the matter and told her to find a certain someone.

A half-hour had passed when someone walked through the door. Without wasting time, Tsunade went straight to the point.

"Nara Shikamaru, you are assigned the mission to find out who killed Uchiha Itachi!" Shikamaru sighed, "Do I have to? Why not get Kakashi to do it?" Tsunade had no time for his whining. She slammed her fists on her desk.

Shikamaru jolted. He hesitated, "A man shouldn't back down to a woman." Tsunade smirked. "Just what I wanted to hear." So with that she sent him off to the scene of battle.

Shikamaru looked at the area. "What a mess. This might take a while." He stared at blood splattered on the trees, the ground, and on the rocks. He looked at the chalked outline of where Itachi's body was found.

His lower body was chalked into the ground, whereas his upper body was chalked into a tree. And on a rock several yards away was his ring, untouched but there was blood and flesh splattered around the ring.

"This is a lot of information already" Shikamaru had studied everyone's fighting techniques, and intentions.

Deidara had always wanted to beat Itachi and his Sharingan ever since Itachi had beaten Deidara into making him join Akatsuki. Sasuke simply wanted revenge and to avenge his family. Naruto wanted Itachi dead so Sasuke would come back to Konoha.

Shikamaru looked around the scene again. He spotted several items that he could use as evidence.

"Several trees are blown away. That could only be Deidara. A few of the boulders have craters in them. Naruto and his Rasengan only could make that kind of damage. And there are many holes in the ground. Anyone could have done that." Shikamaru thought to himself for a while.

"Deidara uses mostly bombs. Made of clay to be clear." He looked for any clay. He spotted clay on some of the leaves in the trees. "If the clay is high up in the trees, he must have been attacking from the air. He must have since the damaged trees are only damaged at the top, not the stump." Shikamaru thought about Deidara then looked back at Itachi's outlining. "And if Deidara had killed Itachi, Itachi's body would have been burnt and or in pieces. And to top that off nothing is blown or in pieces near the outlining." Shikamaru leaned on a tree, "So I can eliminate Deidara as a suspect which leaves Sasuke and Naruto." He smirked. This was going along quickly.

Shikamaru had put into thought of Sasuke and Naruto working together to defeat Itachi, but knowing about Sasuke, that seemed out of the question. He looked around to see if he can spot any other evidence.

He spotted a piece of white cloth and a piece of red a few feet from it. He walked over to the pieces of cloth until he saw clearly that there was a kunai pierced into the ground that pinned down a rather large piece of black clothe.

He was trying to think about the white cloth, the blood stained one and the kunai and black clothe. They were all aligned in a straight line. Shikamaru was stumped for a while until it hit him. "That's it!"

Flashback to the battle last night

"What's wrong Sasuke? Still stuck in genjutsu?" Itachi was facing Sasuke with Sasuke's sword in his hand. Itachi wielded the sword twice through Sasuke. "Gah……….." Sasuke coughed out blood. The blood dripped onto the ground next to a piece of his robe that was sliced off. Sasuke then ripped off a piece of his robe that was sticking to a bleeding wound. He didn't want the robe to stick to the blood when it dried up. Itachi himself was covered in several cuts and wounds. "Damn Deidara, he escaped when his clay ran out." "Little brother I'll finish you!!!" Itachi wielded the sword one more time but when it was only a few inches away from Sasuke's chest, he felt a sharp pain in his left shoulder. Itachi dropped the illusion and huffed a kunai had gone through him. Itachi winced as his blood trickled down his skin. Naruto stood on a tree branch behind them. "Don't you dare kill Sasuke." Naruto was almost at his limit. "Sasuke, don't you dare die on me!"

Shikamaru look at the scene closer. The dirt around the kunai and black clothe was spreaded out in circles. "Naruto and his Rasengan must have gone into Itachi." He backed away, but tripped into a ditch. "Eh……." Shikamaru sighed and got onto his feet. He looked back at the ditch. His eyes widened. "Th-this is!"

The ditch was stretched from the pieces of clothe all the way to Itachi's outline. Shikamaru ran back to Itachi's outline. "Why didn't I see this before?!" Shikamaru backed away and sat down onto a rock. He sighed. "Then that's settled."

Naruto jumped from the branch with a Rasengan ready. Itachi was, for the first time, worried about himself. He was about to try genjutsu one more time. "Sasu-!" Itachi was cut off by Naruto when the raged demon fox chakra flowed from Naruto's Rasengan slashing through the Akatsuki member's upper back. "Bastard!!!" Naruto pushed the ball of chakra even further into Itachi's back. Sasuke's face became pale. He finally had a chance to kill his brother. The moment came at last. Sasuke used the last of his chakra for one last Chidori. "Itachi!!!" The force of Sasuke's hatred and Chidori blew Itachi away. Itachi's head went back as he screamed in pain. His back crashed down onto a tree. The Chidori was over. Sasuke stood over Itachi's body. Sasuke panted, "This is for the Uchiha clan. For mom and dad." He jerked his fist back out of Itachi. Itachi's eyes closed with the Sharingan stil intact. "Little brother………." Sasuke stood over Itachi, using the tree as support. "…….." Sasuke went unconscious and fell. Naruto was there to catch him. Naruto held Sasuke and looked at him with care. "So are you coming home now?"
