It could be that I'm REALLY slow about this, but is the actor who played "Doyle" on AtS the same actor who played "Mark" on Roseanne?  Y'know, Becky's greasy-type boyfriend?  They look awfully similar, and after I started wondering I saw some Roseanne reruns and it sounds like he has a suppressed Irish accent.  Also, it was my understanding that the actor had passed away.  Again, I'm sure this is old news, but how did he die?

Hey! You're right - sadly - on both accounts; he was in Roseanne and he died from an overdose in 2002. For more info on him check imdb. http://imdb.com/name/nm0703849/
