I suspect there were many defendants, as the claimants searched for the deep pocket. The security company may have substantial insurance, for example. Perhaps he can now afford to have his skull rebuilt. I wonder if they postponed the reconstruction either due to lack of funds, or they wanted to make an impression on the jury at trial. If I was the plaintiff counsel, his appearance alone would drive up the value of the case, as everyone looks at him and goes 'ewww'. So if there was no clinical urgency to have the reconstruction done, better to hold off for the jury.
