They usually don’t confirm anything until they’ve completed their examination/investigation. That can take way longer than people think. There was a woman here who committed suicide and people were speculating that her ex actually killed her so the case was getting a ton of attention, and it took months for the coroner’s office to release their final results. Another woman definitely was murdered by her husband a couple years ago. Her remains were found last September and the results were just announced a couple weeks ago. It’s totally normal that they wouldn’t say anything in this case yet.
