From the SGP.aero site:

During the last race day the tracker signal from GN Tomas Reich was lost whilst he was flying along the ridges south east of Santiago.
An aircraft was despatched from the airfield and the Chile search and rescue were alerted. They found the glider on the hill side and Thomas was found to be alive but injured. Once he was stabilised by the paramedic crew he was taken aboard the helicopter to Santiago hospital.

Unfortunately Tomas died during the evening from the injuries he sustained during the accident.
The news of Tomas death was relayed to the competitors and organisers at Vitacura a short time after the closing ceremony of the contest.

Our thoughts and prayers are with his family and friends during this tragic time.
