I didn't see a thread on this yet, but it looks as though John Coughlin's mom has passed away, too.
From his Twitter:
The old house feels empty. I just want to hear her voice or give her a hug. Call your folks today for me and tell them you love them.Poor guy.Feel like I'm making this up as I go along. I'm trying to learn fast though. Dad needs me and Mom is watchin.
