Oven Trouble

get outta there as far as you can, tom, before a bison gets you

Okay, the crime seems to be not perfect, but rather non-trialable. This would open a loophole so that the Sherriff may take the "perfect murderer" to investigate the case at the crime scene, and in an attempt to reconstruct the crime, shoot a bullet to the accused's head... case closed... A loophole also works for the rest of society...
In my opinnion a percect cirime is always the one not even noticed, so presumable there are tons of perfect crimes, just noone knows about.. ;-) ;-(

Rest assured that more and more murders (and other crimes) will be solved thanks to facebook, tiktok and instagram because the perpetrators are stupid and feel it necessary to post their crimes to these media sites.
