Jennings told Detective Longshore that when he heard those gunshots, he took cover behind his own car until his supervisor got there.

And then, reluctantly, he went down with her to get a closer look.

He said that was about 9.45, a few minutes before the first responders arrived.

Later, Jennings told Longshore he felt bad that he didn't see more.

It bothers me every day to know that I didn't see it.

Memory is a mysterious and not always reliable process.

Storing bits and pieces of information in the brain.

Then retrieving them.

Crystal clear, apparently, in the moments immediately after an incident.

And increasingly unpredictable as time goes on.

That's why investigators decided on a special type of questioning technique for Jennings called a cognitive interview technique.

Recalling what he had seen or done earlier that day might help him remember things.

Missing details.

If you were to lose your car keys, as we all have done, just trying to think back, you know, okay, where could they be?

You come up with a blank.

But if you can put together what you did

For the hours before that, all of a sudden it may come to you.

Sure.

You just take it step by step.

Jennings looked relaxed in a sleeveless t-shirt and comfortable shorts, like he was chatting with a good friend instead of with Detective Diane Harris about a gruesome murder.
