Bummer news but not surprising.
Jeff Conway overdosed back on May 11th and has been in a coma since. His manager has suggested it was most likely pain pills that caused the overdose. I believe it. I watched Jeff on two episodes of Dr. Drew Celebrity Rehab and the dude had some serious demons, one of them being his jack wagon of a girlfriend, Vicki Lizzi. She liked him on drugs so she could share in them and keep him under her control. Wonder what she'll do if he doesn't make it? It's not like he had tons of money anymore, besides she wouldn't be entitled to any of it unless he put her in his will, which is possible.
I really loved Jeff on Taxi, he was so cool... hopefully he can pull through but I doubt it. So sad.
