I'm not sure why you think the 0.5% figure is relevant. One of them was 62. Even if they were both 45-55, their risk of death would no doubt be dramatically higher than the mean. They were both whistle blowers, and not just ordinary whistle blowers, but whistle blowers in a high profile story. IIRC, at least one of them had been fired from their job in the last year. That's not average for that age group.
Plugging that in the binomial calculator, P(X>=2) at 32 trials is... 0.09%!! Astronomically low odds.
And you are right, their deaths are certainly not independent :)
