After they get to the camp Murdoc has his camera, although he apparently wasn't carrying it while chasing MacGyver through the woods.
Murdoc uses a 35MM-film "still" camera to photograph the "banquet-table death" scene, yet the "view through the camera" shot shows a b&w-TV-monitor viewfinder and a lighted "recording" indicator, as would be seen in a VHS movie camera.
In a classic instance of a Contrived Convenience, MacGyver's Phoenix ID card and money is left by the car so that Murdoc will be able to make use of it for his purposes. No explanation is given is given for why MacGyver would do such a thing.
