Transcript

[Josh Mankiewicz]

Hey, it's Josh Mankiewicz from Dateline with a special preview of my new podcast called Trace of Suspicion. Death comes for us all eventually. We can never know exactly when, where, or how. What is known is that the Grim Reaper is always out there waiting, checking our names against a list, like some bill collector on commission. United States Marine Sergeant Todd Summer had every reason to think his appointment with death was still decades away. After all, he was only 23. Except sometimes the years don't matter. As he got ready for bed that night in February 2002, the Reaper was watching. Todd had been battling some kind of bug for more than a week. Nausea, diarrhea, stomach pains, chills, fever, the full menu of misery. The doctors at the Miramar Marine Base in San Diego thought this might be food poisoning. Maybe that gas station egg roll he had eaten. We do not know how much sleep Todd Summer actually got that night. We do know that at about 1:30 in the morning, his wife Cindy was awakened by the sound of her husband gasping for breath.

[Cindy Summers]

He got up and he walked towards the bathroom and turned around and just looked at me and, like, just couldn't catch his breath.

[Josh Mankiewicz]

Years later, the memory of that night is still fresh for Cindy.

[Cindy Summers]

I went over to him, I'm like, what's the matter? He just looked at me and he said, I'm all right. I'm okay. I'm fine. And then he just fell down and I just kind of freaked out.

[911 Operator]

Come on.

[Josh Mankiewicz]

That is Cindy back in 2002, on the phone to 911911.

[911 Operator]

What happened to him?

Okay, the parents don't always.

Come on.

Go on the wherelet now.

[Josh Mankiewicz]

Cindy remembered the basics of CPR from her days as a swimmer in middle school and says she did what she could.

[Cindy Summers]

I'd never done it before other than on a dummy, so I really wasn't sure the exact sequence of how things should go.

[Josh Mankiewicz]

A platoon of paramedics, EMTs, and cops were only minutes away. But by then, it seemed the Grim Reaper had her husband in a death embrace.

[Cindy Summers]

Then police and fire got there and it was just. They had taken me out of the room and it was just all a blur from there.

[Josh Mankiewicz]

This story is about the why and the how of Todd Summers death that night.

[911 Operator]

What I want you to. What am I going to do?

[Josh Mankiewicz]

It is about the wife he left behind and the questions that have persisted for more than 20.

[Cindy Summers]

Well, we learned that they had some money issues.

[Josh Mankiewicz]

It is a story about private behavior and public shame.

[911 Operator]

She started having a lot of people over and a lot of parties shortly after his funeral.

[Grief Expert]

I understand everybody says it's the sex. We understood how it doesn't look good. The experts say that people do some pretty strange things in their grieving.

[Josh Mankiewicz]

And it is the story about investigators who found reasons to believe Todd Summers sudd was really a cold and calculated case of murder.

[Investigator]

This was really strange for a 23 year old, seemingly healthy Marine to die. So why don't we run one more test because poison could have been an option here.
