I contacted Lukic with the cam owners info, and he called him a couple days ago, so as far as I know the gear has been returned. Thanks to Lukic and all involved. Best wishes to the climber and belayer.
I found a gray Petzl Elios helmet at Exit 38 on Sunday evening, the 10th of May. It was on the rocks across the railroad grade from write off rock I believe. Right by the trail down under the bridge. Sorry, I don't have a guidebook or good knowledge of the area.
