I am sorry to hear this - we had a case together a few years ago. Dennis Cusack was a pleasure to deal with, a straight shooter, and a really good guy in my experience. My condolences to the family. Goodbye Dennis Cusack, you, sir, are missed.

My heart goes out to you and Dennis´ entire family on your shocking loss. Dennis was my partner for the last 15 years (I retired just this month). His office was a few doors down. We often shared stories of our respective Rugby days at Norte Dame. He was a great guy and will be missed by his friends and colleagues, but none so much as by you, his bride and children. May God be with you in your time of loss and sorrow.
