First I've heard of that. These same neighbors thought this was a normal family too, I guess.
From Channel 5, KSDK:
Neighbors heard "constant banging, screaming, even whimpering" and "a lot of vulgarity" coming from Devlin's apartment.
On Drudge & MSNBC Home page they are articles stateing neighbors heard screams , whimpering & banging noises . They called the Kirkland cops about the noises too ! I believe it was the day after Ben was taking the call was made to the cops !
