What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The jumper was the second jumper in a group of three and the group was the next to last of several previous groups. His two companions lost sight of the victim relatively soon after they exited and did not witness anything abnormal. After the other jumpers landed the victim was unaccounted for. A local search was conducted and in a short time he was located about 1 mile from the airport on a hillside. An ASI inspected the parachutes. All seemed to be packed appropriately and would have operated normally. No determination could be made as to why no attempt to deploy either chute was made. The exit altitude was 17,500'. Other jumpers told law enforcement they all had oxygen and were using it as required. However, the investigating sgt. reported that the system was simply a tank with a splitter valve with tubes running to each jumper. He was unable to inspect the accident aircraft but was shown another aircraft at the event and was told by some jumpers that the systems were all alike. An autopsy was ordered but it may be 10 weeks for the results. This event was not subject to any FSDO or ATC requirements. The jump aircraft were all contacting den center prior to each jump.
