There is also a perception that Chai Vang, had a hunting partner and that they were possibly responsible for shooting another hunter in 2001. Not sure if this theory was ever proven further, but it does set up a uneasy dynamic in that there is the spectre a killer, of specific descent, in the midst during hunting season.

Clark County sheriff's deputy said last weekend's shootings had vague similarities to the death three years ago of Jim Southworth, 37, of Medford, Wis. Southworth's body was found on family land Nov. 24, 2001, a day after he had gone deer hunting by himself.
"We're not considering Mr. Vang a suspect. We're considering him a possible witness," said Chief Deputy Jim Backus of the Clark County Sheriff's Department in Neillsville.
Hmmmm....interesting. I had not heard about that story. The way he hunted those people down in such a cold and calculated way and the fact that he showed no remorse whatsoever makes me wonder.
