Marshall police said in a news release that the accident happened about 11 a.m. Sunday near Brooks Field in Marshall. The site is about 15 miles east-southeast of Battle Creek.
Deputy Chief Scott McDonald said George Speakman of Angola was found on the ground, just south of the airport.
McDonald said Speakman was with some other skydivers, but they didn't exit the plane after realizing something was wrong with Speakman's jump.
McDonald said Speakman was an experienced skydiver.
The statement from authorities says an investigation will involve police, the Calhoun County medical examiner's office and the Federal Aviation Administration.
