I agree. Seems the roommate is setting up Plausible Deniability. He knew but how will They prove it?
We do NOT know where "love aka he-she" was during this texting. Implies that he was in the apartment because Tyler says to look under his keyboard...
But where was "he-she" between the kill shot and the texting.
I'd like to see a picture of the keyboard. I bet there's a drawer below...
So why wait 5 or 6 hours to text "he-she". Makes no sense.
