Aug. 21, 2011— -- Handwritten letters are considered by most to be a thing of the past. In the age of email, texts and blogs, to receive a letter is, for many, a rare occurrence.

And yet letters written by two women became the centerpiece, if not the catalyst, in two high-profile murder cases: State of Wisconsin v. Mark Jensen and State of Arizona v. Douglas Grant.

When 40-year-old Julie Jensen, a wife and mother of two young boys, was found dead in her bed in December 1998, investigators initially believed suicide was the likely cause of death. District Attorney Bob Jambois was at the Jensen home that day and thought differently.

"It didn't look right," he told ABC News. "All kinds of things didn't fit."

But when the autopsy came back, his suspicions remained just that. There was no evidence of foul play.

It wasn't until a few days later that Margaret and Ted Wojt, Mark and Julie Jensen's neighbors, walked into the police department and handed police a sealed envelope. Just a week before, Julie had knocked on their front door and handed it to the couple. They told ABC News that Julie asked them to deliver it to law enforcement authorities if anything happened to her.
