Jennifer vanished sometime in the overnight hours.

Right now there is no trace.

Investigators say evidence lead them to believe that she's dead.

Stick my nose back on the trail. That's all I can do.

This is already gone.

Already gone.

Already.

All right. In 1989, the Detroit suburb of Wyandotte was witnessed to the deaths of four children under the age of eight.

But what really happened? How does the family station wagon end up sinking in the Detroit River? Come with me to a warm August night in 1989, when the Delisle family outrunning errands with his wife, Suzanne, and their four children, Brian, Melissa, Catherine, and baby Emily.

The family is piled into a 1970s yellow-brown station wagon.

The vehicle originally belonged to Lawrence's father, who died by suicide just a few months earlier.

Things are looking up for the Deliles. Lawrence's co-workers at the Lincoln Park area tire store where he worked, describe him as a proud dad,

and a happy-go-lucky type of guy. Lawrence coached Little League, participated in family activities,

and spent his free time with his

four children. Suzanne is a stay-at-home mom to their many kids. The family was in the

middle of a move. They were leaving their cramped townhouse in Taylor and going to a roomier place

in Lincoln Park. They were also looking forward to having a yard for the kids

to play in. Winifred Dobert, the Delisle's neighbor for two years, described them as an

affectionate family who did everything together. She recalled the children playing happily,

and their daughter Melissa often greeted her with,

Hi!

Even repeatedly throughout the day.
