I think Warmington has been around the block more than a time or two. Any reporter know a police officer isn’t allowed to touch the scene when deaths are deemed “suspicious”. Their role is to protect the bodies and the crime scene to ensure everything is undisturbed, while waiting for the coroner and forensic pathologists to arrive. Prior to the autopsy, which certainly wasn’t completed in the Sherman residence, no police officer would’ve been able to determine either the cause or manner of death by visual observation, the same day the bodies were discovered.
My theory is the source was not a police officer and both TPS and the media intentionally allowed the fabricated story to unfold until the official double homicide announcement but why, I’ll leave it at that. Other than to say during investigations of staged homicides, obviously the murderer/s intended the deaths to be perceived that way. Even if LE knew better, there’s no immediate benefit for LE to show their hand.
