Very sad to learn of this news.
I remember him well as Robbie in Fair City. He was a tour de force on that soap. 47 is so so young to go - TBH I thought he was a good bit older
I also knew Karl from a support group I attended and he was a decant, down to earth chap.
Poor guy. I wonder if he was ill for a while, recently he was doubled over a lot and leaning on counters in the show, and after being away for a while, he returned stooped over and it was explained that he put his back out excercising.
