John Frederic Slater

November 9, 1961June 2, 2012

John Frederic Slater passed away June 2, 2012 in El Fuerte, Sinaloa, Mexico, while flying his airplane on a goodwill mission for Liga International (Flying Doctors of Mercy). As a devoted volunteer, John transported doctors, nurses and other volunteers to provide free medical care for the poor and will always be remembered as an angel of mercy and hero. John touched many lives personally and professionally with his presence and his infectious laugh; he will be greatly missed by the community as a successful businessman, family man and friend.

John was born November 9, 1961 in Tucson, AZ to Eugenia and Albert Slater. John was a loving husband, father, son, brother and papa. Like his father before him, John loved flying and was a private pilot for over 24 years.

John is survived by daughters Vanessa Slater-Wingerter and Brooke Slater and their mother Elaine Slater, granddaughter Jordyn Wingerter; his mother Eugenia Slater; sisters Cathie Eroh, Jeanette Ham and Carla Kettrick.

John, your family will be in my prayers always. I am sorry you were taken away from us so prematurely and I'm looking forward to meeting up with you again someday. May God Give Rest and Solace to Your Soul.

I only met John once, at the wedding when my father and Jean married (some time after their respective spouses had died). It was clear that the Slater family, like my family, was very close and caring. I was so happy that my Dad had found another wonderful woman (and family) to be a part of his life.

I can only imagine the grief his mother and sisters feel. This is the downside to being so close, but who would have it any other way? The only consolation, if there is any, is that John died doing what he loved -- flying -- and helping those people who need help the most. Who among us could ask for more?

I go back a little further as a freind of Elaine from Flagstaff, we were lucky to have met wonderful men at NAU and then be able to move and be together here in Tucson. John was a awsom father and freind. My prayers go out to Elaine and Vannesa may God Bless you and your family...

John always carried a kind smile. It was clear he enjoyed his missions down to Mexico,to help others. My deepest sympathies go out to his entire family at this time of grief.
