Is this a disturbing trend???

...or am I suffering from confirmation bias?

From CNN: Florida man kills wife, 2 kids, himself, officials say

It seems like we are seeing a lot more murder suicides lately. Or are they just being reported more often?

Just Google MURDER/SUICIDE and it's sickening. I'm not sure, but I think this kind of crime disturbs me more than any. I'm sure someone can think of one that is worse, but what about one that happens this often?

What motivates someone to kill? I had a time in my life when I considered suicide, fortunately, I came to my sense. But how does one progress to killing their own children or their spouse? I have difficulty understanding most physical violence toward your loved ones.

When does your brain's ability to logically assess your situation break down into this kind of madness? What is happening in the brains of these people?

Two of the couple's children -- 5-month-old Zack and 7-year-old Ryan -- also were killed, but a 13-year-old got away, with the father chasing and firing after him, officials said.

It makes me ill to think about something like this. The child who survived must feel like his life is over.

Are there statistics kept on this type of crime? Is this the result of the poor economy? I just don't get it...
