Memorial services were held Saturday for two Lubbock couples killed in Monday's plane crash.
Paul and Marcia Johnson and their friends Bill and Betty Roach were returning to Lubbock, when their plane crashed in Branson, Missouri. Federal investigators still don't know what caused the plane to go down.
The pilot, Dr. Paul Johnson, reported some sort of difficulty before the crash. Family and friends remembered the four in two separate memorial services.
