The autopsy concluded that Baader shot himself in the neck. 3 cm above the hairline in a direction that made the bullet come out through the forehead from a straight trajectory, with a 7.65 calibre pistol which is considered implausible.[42] Moreover, the investigation carried out by the ballistic expert Dr Roland Hoffman using Baader's gun, showed that the bullet must have been fired from a distance of between 30 and 40 centimetres, which is considered likely impossible. The only case according to Hoffman that such small amount of gunpowder that was found, would fit the shoot by contact scenario would be if a silencer was used, however apparently the gun had no silencer when the body was found[43]
