It was the Japanese-American friendship day. The Japanese representatives chose the American Museum of National History as the place to do their program. The Japanese carried with them some of their national treasures and displayed it in the museum, covered in expensive silk fabrics, till it’s ready for viewing. But the night before the day the national treasures are ready for viewing, one of the treasures were stolen. It was the samurai sword “Kotetsu.”After the investigation, the police asserted that they have 5 suspects for the case. Surprisingly, all the suspected people are students coming from the same school belonging to the same class. The students are My Melody, Kiki, Badtz-Maru, Lala and Pochacco.  Here are their statements. Listen to them well, detective:

My Melody: I was at the museum researching something for my project. I was there till that time because I was waiting for my parents to fetch me. It was probably Lala who stole it because she’s interested in the samurai culture very much.

Kiki: I was with Badtz-Maru and Lala all the time. We 3 took constant breaks at the museum’s cafe. If you’re gonna ask me if there was something odd with Lala, well, she was going to the comfort room very often that night. But still, she left the library with us and carried nothing but her books. 

Badtz-Maru: As Kiki said, we we’re just studying for the exams so that explains why we were there till that time. Something’s odd with Pochacco though: he had Manila papers, crayons and glue with him.

Lala: Okay. I admit I am very interested in the Samurai culture but I am no thief! I was taking constant breaks that time because it was very cold and I need to urinate. Also, how can I even leave the place without passing those sensors at the door?  

Pochacco: The reason why I was with art materials that time was because I had to do an oral report for our History class before the final exams. It’s not true that I wasn’t researching for it. I already did my research on the museum the night before yesterday. Besides, why would I be interested in an old, reddish, sword? I have no interest in swords.

So, who stole the treasure?
