The stab wounds from a knife and a javelin head would be VERY different. Knife wounds would be narrow and slender, a javelin wound would be round. The difference in wounds would be obvious. There is no way such wounds could be confused with each other. See more

Multiple sharp-force injuries, ten in total. One puncture wound on his upper back, eight more puncture wounds on the front of his torso... and a single wound in his upper thigh. Combined, the puncture wounds caused extensive internal bleeding. This man died a brutal death.
