Never EVER watch Supernatural or Flash/Arrow/Super Girl at the same time as Criminal Minds or any other police procedural.
Something weird happens and someone dies the 1st 20 seconds of Supernatural and Criminal Minds. Bam! Both Sam and Dean show up pretending to be FBI, and the BAU who are actually FBI show up to the scene.
S & D: Did you smell sulfur? Cold spots? Black eyes? Did the victim have any enemies?
BAU: Were there any witnesses? Fingerprints? Foot prints? Did the victim have any enemies?
Witness…the SO of the victim. I heard her in the bathroom screaming! *sobs* The door wouldn’t open as hard as I tried.
S & D: Note the rosary she always carried is missing. Note there are no locks on the doors.
BAU: Note that the victim suffocated in the tub, but was not drowned. Note there are no locks on the doors.
S & D: Get EMF readings from the room. Vengeful spirit. Begin to take EMF readings from other parts of the farm where the murders occurred. Know the owner personally and eliminate him as a suspect.
BAU: Suspect owner immediately and arrest him and question him thoroughly. (BTW, they don’t torture the suspect or throw holy water on him.)
S & D: Find drawings on the wall indicating one of the children in the home was involved in a terrible accident and the mother died in the burning car. They cannot burn and salt the bones. They burn the child’s toy. Bullies get injured in lawn mower incident.
BAU: Notes accidents continue to happen on the farm even though owner is in custody. They inspect the new incidents and do not discover any causal relationship to the other murders. Dismiss new incidents as unrelated.
S & D: Vengeful spirit believes S & D are threatening the child and attacks the child’s guitar teacher and S & D. Dean tells child to demand Ghost Mom to leave and that he will be ok. Spirit returns to pre-dead self and smiles and then flitters off into the after life. (Question: Does the good mom’s evil spirit that committed 2 murders and an attempted murder without remorse or repentance go to heaven?) Crime Solved.
BAU: Finds no foreign matter or evidence in either of the murder scenes, and since the only fingerprints and physical evidence belong to the owner, the owner goes to trial for double homicide. As an ex-convict he never gets out of prison and his creepy home for boys is sold at auction and bulldozed to make a discount mall. Crime Solved.
