The Baltimore Sun has the story on this sad news. Here is Senate President Mike Miller’s statement:

My heart is broken for Mike Busch’s family, the State of Maryland, and the Speaker’s extended family – elected officials and staff that he has been a mentor and coach to over his time in public service. Mike has been a friend for years, and has led the state to new heights of environmentalism and education, while ensuring that a new generation of leaders move our state forward. He was a true model of a State Delegate; he cared for every corner of the state, but never forgot about the people he was elected to represent. I will miss him as a friend and partner in state government and I join all the state in mourning his passing.
