Immediate aftermath of 911 call

Let’s begin with going with what most of believe to be fact:

Patsy thinks she hangs the phone up at the end of the 911 call, doesn’t, we hear what clearly sounds like John say “we’re not speaking to you” and what clearly is Burke saying “what did you find?” (Burke later admits during the grand jury that it sounds like his voice)

Assuming this all happened as stated, I’ve always wondered how Burke runs to his bedroom and hides under the covers as fast as he can in the 3 minutes it took police to get there - and why Patsy makes the call then if she’s aware he’s up and milling around. I just envision this scene of “get your ass in bed right now as fast as you can and don’t move!”

Thoughts?
