I think his mate has been ‘got at’ and forced to go along with the body in the car boot, I don’t think he’s part of all the conspiracy.

Someone I know thinks the barrister was killed because of her humanitarian work and the Americans wanted her gone, and it’s them who are behind it all. The soldier just happened to be her last case, and the Americans set him up to make it seem he killed her.
