The operators of Vessel #1 and #2, both personal watercraft (PWCs) were riding in the vicinity of Crow Butte Park on the Columbia River.  They became bored because there were no waves to jump.  A small boat came through the area and boat operators began jumping the wake of boat.  

Vessel 1 was following Vessel 2 as they each jumped the wake several times.  Operator of Vessel 1 said the last time Vessel 2 jumped the wake, instead of going straight ahead which it had done the previous times, it instead veered right, which put Vessel 2 directly in front of Vessel 1 as it was in mid-air.  This resulted in Vessel 1 landing directly on Vessel 2.  

After Vessel 1 landed on Vessel 2, the operator of Vessel 1 turned around and saw that the operator of Vessel 2 was in the water.  Operator of Vessel 1 checked on the operator of Vessel 2 and saw that he was non-responsive and that his face was cut severely.  The operator of vessel 1 then went to the park to get help, where he panicked and could not remember what had happened and did not know how he got back to the park.  

At some point a third vessel came and brought the operator of vessel 2 to the park.  The third vessel left before the operator could be questioned and attempts to contact her have been unsuccessful.  

The operator of vessel #2 could not remember what happened or what he had been doing.  He was missing teeth, had a broken jaw, lacerations to face and a probable concussion.
