I remember this is what i read from the papers too
On 10 October 2004, Took coaxed Huang Na into a storeroom with
mangoes and a game of hide and seek.[2] He tied her hands and feet
as part of the game and left her in a dark room, where she
accidentally knocked her head against some boxes. When he returned
to the room, she was bleeding from the mouth. Seeing this, he
panicked and strangled her to death with his bare hands, then
undressed her to give the impression of a rape. After this, he
wrapped her body in nine layers of plastic bags, stuffed her into a
cardboard box sealed with adhesive tape, and left the box in the
storeroom.
