It should have been a routine school night in Somerville, Massachusetts for 17-year-old Deanna

Kremann, homework, TV, and a walk home with her boyfriend before curfew.

But by morning, Deanna was gone.

Her body was discovered just a few hundred feet away from where she was last seen.

The community was stunned. Who could do this? And why?

For three decades, Deanna's family and friends have waited for answers,

holding on to hope as forensic science evolves.

DNA and forensic genetic genealogy is now at the center of the conversation.

Could the key to solving this case be hidden in a decades-old sample,

waiting for the right technology, or the right name to match?

I'm Kylie Lowe and this is the case of Deanna Cremon on Darkdown East.

It was the night of March 29th, 1995, and 17-year-old Deanna Cremman was over at her boyfriend's place watching TV and doing

homework. Deanna and 18-year-old Thomas Tommy LeBlanc had been an item for at least a year at that point,

and their studying slash television sessions were a pretty routine occurrence in their relationship.

According to reporting by Peter Galzinnis for the Boston Herald, Deanna had a 10 p.m. curfew,

so when it was time for her to go home, Tommy would usually walk Deanna from his place on Broadway

down to her home on Jake Street, only about a half mile away.

But that evening, as Deanna's curfew approached, she called her mother Catherine Cremant and let

her know she was going to be late. Deanna said, I love you, and Catherine said it back, before

hanging up the phone and drifting off to sleep on the couch. When Catherine woke up around

midnight, she realized that Deanna still wasn't home. Megan Trench reports that Deanna had just received a pager as a gift for her 17th birthday a few days

earlier, so Catherine called the pager, but didn't get a response.
