I've known Keith for some years through his work on the council and we both attended the wedding of a mutual friend a few years ago.
We've always been on very good terms despite the fact I'm Lib Dem and he was a Conservative.
I didn't know Andrea beyond seeing them both at civic events but she was always good for a friendly chat.
I share the community's sense of disbelief and my heart goes out to all of their family and friends.
