But the question of why them remained.

But what if it turned out there was a connection between the suspect and someone in the Bishop family?

Everyone and everything is fair game.

I understood that and so did my family.

What troubled me was the notion that my sister's investigation was hijacked for some other purpose.

I knew that if someone killed them, that evil had intruded into our lives like nothing that we had ever known before.

In the days after the murders, the Bishop family learned from investigators chilling details of what happened in the last moments of the couple's life.

Richard died first.

The gun was put to the back of his head.

He was shot once execution style.

Nancy was shot twice in her side in Amteman.

And then I think at some point she must have realized she was dying.

And so she dragged herself by her elbows over to Richard's body where he lay.

The last thing that she did before she died was to leave us a message in her own blood.

She took her finger in her own blood and she drew a heart and a U. Love you.

Well, it's probably the most heartbreaking thing that you could ever imagine.

When I saw that heart there, mine broke.

When Detective Gene Calvados walked into that basement, he saw the brutality of the slayings firsthand, along with some odd clues.

Near the back fence, a single glove.

Investigators looked into Nancy and Richard's lives.
