On July 11th, 1973, 15 year old Diane Campagna swung her red beach bag over her shoulder and headed out the door of her house in Merrimack, New Hampshire.

She was off to swim in a nearby lake with her friend, 15-year-old and Sarah Delis.

At least, that was the story they told their parents.

Neither girl was expected home that night. It appears they pulled a classic teenager scheme.

Anne told her mom she was spending the night at Diane's, and Diane told her parents she'd be sleeping over at Anne's house.

But their parents weren't suspicious as the girls left for the day.

It wasn't until the next afternoon when the pair didn't return to either home that the parents began to worry.

What began as a missing person's investigation for two teenage girls in the summer of 1973 ended as a double homicide.

In 2023, this case will reach its 50-year anniversary without answers.

I'm Kylie Lowe, and this is the story of Diane Campagna

and Anne Sarah Delis on Dark Down East. On July 12th, 1973, a concerned father walked into the Merrimack, New Hampshire police station.

Dispatch had called for Sergeant Joseph Horrick over the radio

and asked him to come down to the station to take the initial missing person's report

from Marcel Campagna, Diane's dad.

Sergeant Horack told the Concerned Father that they typically didn't take missing persons

report in the first 24 hours because in many cases people turn up in that

window. But the father was adamant and so Horik said that he could issue a

bulletin in the local community and put their physical descriptions over the radios.

Diane was last known to be wearing blue jeans and sandals with a dark blue crop top blouse

and her red beach bag. She had long dark hair and was about five feet

four inches tall and left the house wearing jeans and a red blouse with a

multicolor bag. She too had long dark hair and was about the same height as her friend Diane.
