Ooh, that is creepy about the MacDonald house being left for 9 years. The coolest thing about the case for me was that they figured out that ALL FOUR FAMILY MEMBERS had different ABO blood types. I think that was about as sophisticated as DNA typing went in those days. But with the four different types, they were able to piece together from the blood all over the house what happened and in what order. And it totally contradicted MacDonald's cheesy story. I thought that was awesome, as though the poor souls were able to point to their killer from their graves.

If I remember correctly, the murdered wife's parents began to doubt son-in-law very quickly much like Laci's parents/family.
