On Tuesday, March 8, Diane Postler-Slattery, a member of the Alma College Board of Trustees, and her husband, Donald Slattery, were killed in a private jet crash in Florida.

The couple’s Cessna plane, which took off from Michigan, stopped in McMinnville, Tennessee, before continuing on to Northwest Florida Beaches International Airport in Panama City, Florida, according to sources.

The jet carrying Midland-based MyMichigan Health’s president and CEO is believed to have vanished from radar approximately two miles from the airport.

The investigation has been handed over to the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA).
