Using light from the flame of a cigarette lighter, the Muldoons find baby Christopher safe in his crib.

It would be their first and only sigh of relief.

They found their daughter's roommate Deborah Johnson dead on the sofa bed.

In the kitchen, their daughter Jo-Anne was dead on the floor.

Both young women had been stabbed to death. Their throats had been cut.

More than 50 years later, their murders remain unsolved.

And their throats had been slashed.

Maureen was found lying on the ground outside of her Ford sedan. Jennifer's body was on the floor of the front passenger seat.

More than 50 years later, their case remains unsolved.

Holly was vacationing with her father and brothers at her grandparents cottage in Sturbridge. She had last been seen by her father around 11:45 a.m., heading toward a neighbor's house to play with puppies.

Following a tip from a local hunter, part of a one piece, blue Nike bathing suit is discovered on Whiskey Hill near the Nenameseck Sportsmen's Club on Bacon Road in Palmer, Massachusetts.

The finding launches a full scale, grid-by-grid search over three weeks along eight and a half acres of hillsides and wooded areas on both sides of West Warren Road in Palmer and nearby Ware.

In early June, the intensive search produced a second significant finding, a human arm bone.

Days later, two more arm bones and a shin bone are found.

And then a femur, two rib bones and four vertebrae.

On June 9, 2003, investigators found teeth.

That same day, Worcester County District Attorney John Conte announced the arm bone they discovered in the woods matched the DNA of 16-year-old Molly Bish.

Molly had been missing for three years.
