Deadly workplace?

So, as of June 9th I have been working at the same company for 20 years. It is a manufacturing plant that is part of a global company with annual sales of over $5 billion US. I work in engineering, and have for most of the 20 years I've been with the company. We have around 350 (hourly and salary) people working at this facility at any given time, and I am wondering if we are unusual in terms of deaths when compared to similar workplaces.

This might seem like an odd thing to say, but maybe you will undertand my questioning when I realy some things.....

Not long ago one of our tool and die makers was murdered at a local pub. He was shot 7 times in the back - nasty. This is the first murder in my small city of 35,000 people in about 20 years, and the first shooting murder that I can ever recall. It just happened that this guy worked where I work.

This week, one of the machine operators out on the shop floor killed himself. He apparently shot himself in the head. He seemed like a noral fellow, and whenever I had to deal with him, he was always cooperative and seemed happy.

This is not the first suicide of someone who worked at our facility. About 10 years ago, we had someone kill himself at the plant. He went to the basement of a remote area of our plant, and hung himself. He hung there for about 18 hours before he was found.

So, certainly the guy who was killed at the pub could have been anyone, but does anyone find the rate of 2 people from one plant killing themselves in about 10 years a bit high? I'm certainly not wondering if "I'm next" or anything, but it does make you wonder if there is something about this place that makes it prone to having it's employees kill themselves.

If anyone out there works in a similar sized place, I would be interested to know how many of your fellow workers have "offed" themselves.......
