The NTSB's narrative final · quoted from the NTSB record
The pilot was found deceased in the undamaged glider following a landing to a field near the airport. Postaccident examination revealed an improperly secured aileron connection; however, despite being partially unseated, the ailerons clevis pin remained seated adequately to facilitate operation of the aileron. No other anomalies were detected with the airframe that would have precluded normal operation. Autopsy revealed that the pilot’s cause of death was aortic dissection associated with hypertensive and atherosclerotic cardiovascular disease, with blunt force injury contributing.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CEN22FA224.
