Watch the full two-hour Dateline 'In the Dead of Night' below and keep the conversation going with its producer.

Hi, my name is: Shane Bishop

I've been a producer: at Dateline for 16 years.

My inspirations as a storyteller are: my large extended family in Montana, authors Tom McGuane and Norman McLean.

When I first came across this story, I thought to myself: I've never seen such a stark illustration of the best and worst in investigative work.

My biggest fear about doing this story was: that by merely working on this project we would in some way add to the family's pain rather than provide answers and insight.

The most impressive human beings I met along the way were: Andy, Tami, and Steve Stock.

These are the words I'll never forget: "What if they'd knocked on the door and asked for help? They would've given it to them. They would've got up. Got dressed. Done whatever they had to do to help em get them on their way. I can see Dad putting an arm around a shoulder and saying, son, let's sit. Let's talk. How can we fix this?
- Steve Stock, on what his parents would have done for Jessica Reid and Greg Fester if they'd simply asked for help that night.

The most striking images I saw were: the crime scene photos. I've never seen images of a crime in which more damage was inflicted on the victims.

When it's time to put it all together, I work best when: there's noise and chaos all around me, the product of many years in local newsrooms.

In one word, this is really a Dateline story about: choices -- the most important word in the English language.

Last but not least, I wish: convicted killer Greg Fester would have agreed to our repeated requests for interviews.

Thanks for watching
