Good thing he dropped his gun.

I was thinking how lucky it was for Jonas that Jon left his gun at the scene of the crime. Jonas was able to use it to switch the bullets in his dead partner.

If Jon Holt hadn't left the pistol, then Jonas would have been up sh!t creek without a paddle. The only possible thing for him to do would be to switch all of the bullets from Jon's gun in the evidence room for ones from his pistol. He'd then have to make his coworkers think that the killer would be using his model gun. Then again, that wouldn't work, because his gun was something only Swedish police carry, and they'd know it was Jonas. So yeah, he would have been done for.

Any ideas how Jonas could get out of it?
