A number of bolts pierced the elf. These bolts were completely common in nature. They did not hold any enchantments, nor did they contain any poisons. The elf was shot completely from his front, and the wounds were consistent with a well-trained marksman(s). His body was found looking towards the gates of town, as if he was looking at his attackers when it happened, so it is assumed that they came from towards the desert, or are trying to lead us to believe such. The bolts being as common as they are leave no trace of tracking for them.
