Mark John Keating, age 68, of Huntington, NY, died peacefully Sunday, July 8. Cherished father of Ryan, Cindy (Larson), and Kevin, devoted grandfather of Weston and Liam, and beloved brother of Maryann (Maresco), Al (dec,), and John (dec.). Mark served honorably on the Nassau County Police Force for 35 years. An avid golfer, selfless friend, and loyal companion to many, Mark was always in good humor and never passed up an opportunity to share a laugh, often at his own expense. He will be deeply missed by all of the many people he touched throughout his life. The arrangements were handled by Oyster Bay Funeral Home. In lieu of flowers, donations can be made in Mark’s name to the American Diabetes Association (http://www.diabetes.org).
