On the 60th anniversary of “The Day the Music Died,” forensic anthropologist Dr. William M. Bass will present a lecture and slideshow about his 2007 exhumation of J.P. Richardson Jr., better known as The Big Bopper. Richardson died in a plane crash near Clear Lake, Iowa, on Feb. 3, 1959. The crash also killed singers Buddy Holly and Ritchie Valens and pilot Roger Peterson. In 2007, the Richardson family moved his body from a grave in Forest Lawn Cemetery in Beaumont, Texas, to a different location in the same cemetery and requested an examination by Bass to answer some lingering questions about Richardson’s death. The lecture will be held at the Knoxville Convention Center, and radio personality Frank Murphy of 93.1 WNOX will serve as emcee and facilitate a question-and-answer period.
