73 duster drivers door won't close

I worked with a guy. Don't know how he did it, but on a 4 door caprice he got all 8 fingertips caught between the front and rear door down by the bodyside moldings. There were only 3 bodyguys at that shop and the other guy and myself were outside getting in my truck to go to lunch when we heard the screaming. I ran in and the door was fully latched on his hands. 2 minutes later and we would have been down the road and the office personnel would never have heard him in the other building.
