Tonight on Dateline. This was a very cold calculating plan. This innocent, kind loving woman. Those two boys were everything to her. Just imagine all that Julie lost.

Julie Justin was found covered with a blanket on the bed.

You've got a suspicious death. Is it a homicide? Is it a suicide? We just didn't know.

One of the things that police learned, Julie had an affair.

Correct.

She reported having pornographic pictures

that left outside the home like on the car or in the garage.

These photos are showing up at the office,

their phone calls, heavy breathing.

Somebody was stalking her, harassing her.

Who would harass a couple like this?

We had talked about potential suspects.

Nobody.

Nobody deserves what she went through.

She wrote a letter.

She said if something happens to me me please hand this to the police she

predicted her own death she did essentially talking from her grave I want Julie's

voice to be heard.

A young mother, dead in her bedroom.

Was it murder?

The biggest clue of all was one she left for investigators.

I'm Lester Holt, and this is Date Live.
