TULSA, Oklahoma - A memorial service will be held Thursday for Dr. Garrett Coble, 29, who lost his life in a plane crash Friday. Coble was a passenger on a twin-engine Cessna 401 that crashed on the way to a Teen Mania Ministries conference in Iowa.

The memorial service will take place at 2 p.m. in Christ's Chapel on the Oral Roberts University campus.

The crash also claimed the lives of Oral Roberts University graduates Luke Sheets, 23; Stephen Luth, 22, and Austin Anderson, 27.

The only survivor, Hannah Luce, 22, is recovering from burns sustained in the crash.

Coble was an assistant professor of marketing at Northeastern State University in Broken Arrow.

"The NSU community is extremely saddened by the loss of Professor Coble," said NSU President Steve Turner.

"His service to our students at the Broken Arrow campus was meaningful and appreciated. Our thoughts and prayers go out to his family and friends and to his friends' families who also experienced significant loss as a result of this tragic accident."

Coble had served on missions for the teen ministry group founded by Hannah Luce's father, Ron. Luth and Anderson had just accepted positions on the marketing staff at Teen Mania Ministries.

Coble received a Ph.D. in business administration with a marketing emphasis from Oklahoma State University, according to a release from NSU-BA. He received three outstanding graduate teaching awards while at OSU.

He taught at ORU from 2010-11 then joined the faculty at NSU-BA in August, 2011. 

"In the short time Garrett was a faculty member at NSU, he had a positive impact on his students and on his faculty colleagues in the Department of Business Administration and the College of Business and Technology," said Dr. Roger Collier, dean of the NSU College of Business and Technology.

"He was at the beginning of a promising academic career. We will miss him."
