I trusted him and we worked together with an almost magic energy.

Im so grateful for the opportunity I had to experience that joy.

I will miss him always.

A great light has dimmed in my life.

And for all who knew him.

His powerful onscreen presence as the no-nonsense mobster earned him a Daytime Emmy for Outstanding Supporting Actor in 1992.

He was nominated for a second time in 1993.
