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.

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.
