I've been translating the results of the scan of Tut...which can be also find here

I think you should read it carefully....it tells a lot of things
1-he didn't die for a blow to his head, scientists have proven that the piece of bone has broken by the priests during the embalming process.
2- the sternum and ribs have been cut...so it is quite probable that it has been done by Carter's team while looking for artifacts of gold (which seemed to be their first aim!!)
3-Tut could not have died due to the break to the leg bone (this cannot cause death) and no sign of infection was detected in the soft tissues in the area, so he could not died for such an infection.
4- it is too quite probable that the boneof the leg was broken after his death, by Carter's team while trying to unglue the body from the coffin. Scientists found few remains of resins along the edges of the broken bones which, at first sight,made them think of the fact that it could happened a little before Tut's death, but then they soon realise that those resins where just few drops that could have fit the internal side of the fracture due to the fact that Carter's team used lamps to heat and unglue the body from the coffin, so the resins melted inside the edges of the fractured bone of the left leg.
