Michael Keenan (12 December 1939 – 30 April 2020; age 80) was an actor who played roles in three Star Trek spinoffs, Star Trek: The Next Generation, Star Trek: Deep Space Nine, and Star Trek: Voyager.
He is probably best known for playing Mayor Bill Pugen in Picket Fences during its first season in 1992-1993. That series featured many actors who appeared on Star Trek, including Ray Walston, Roy Brocksmith, and Leigh Taylor-Young.
Keenan passed away on 30 April 2020 at the age of 80 of "non-COVID natural causes". [1] [2]
