Obviously the student is seeking information about Huck's faked murder in
Chapter 7 of the novel, wherein Huck, having had his fill of Pap's
murderous DTs, kills a pig, smears its bllod all over the hut and an ax
handle, and drags the carcas to the river to make it appear he was murdered
and his body left in the river.  He, Jim and Tom all refer to his having
been murdered, although he is hale and hearty, which may account for the
teacher's referring to his faked death as a murder.   This must be her way
of trying to get students to read--if they think it's gory, they'll read
it.
