Yea, it was a pretty chilling event. Long story short, Shane (disgraced former police officer) didn't want himself or his pregnant wife to have to go to jail for some murders that they were linked to. They had a very young son (how old was Jackson, 2? 3?), and Shane didn't want him to grow up in foster care knowing his parents were murderers, or for his unborn daughter to share a similar fate. So, he drugged some drinking water that he gave his wife and son, and they simply died in their sleep. "Happy and innocent. Just the way I found them", as his suicide note read. He placed them side by side on a bed, and left a bouquet of flowers in his wife's hands, and a toy police car in his son's hands. Similar to Chris Benoit leaving bibles next to Daniel and Nancy's bodies. While Shane was in the process of writing his suicide note, an army of police knocked-down the door of his house, and when a couple female officers turned a corner and saw him sitting in his bathroom, he shot himself in the head. I don't think chilling is a proper word to describe the event, it was just terribly sad more than anything.
I should've continued watching that show.
