I think that in the affadavit CW told LE that the keypad to the garage was broken. As he was racing to get home. So they could not get in before he was there.
That said, there was no way in before he got there, everything was locked. The latch on front door was locked from the inside so there was no way into the house, even with a key, until he got there.
I'm thinking he used a car garage door opener to let LE in. I am very curious to know if that keypad will ultimately show to be broken.
Or if it's another one of his lies to buy time.
All imo and per affadavit.
