FLORENCE, Ky. -- They made it official 57 years ago.
Sunday marked the anniversary of the day Bill and Peggy became Mr. and Mrs. Bill Stephenson.
They were high school sweethearts drawn together as teenagers: a talented athlete and a cheerleader.
"They were king and queen of New Haven High School," said Beth Stephenson-Victor, their daughter.
On Sunday, Beth smiled as she thumbed through a scrapbook she made for a previous anniversary her parents celebrated. She loved making them for her family.
But that all changed over Memorial day weekend 2011 . That's when Bill and Peggy Stephenson, both 74, were found dead in their Ridge Edge Court home in Florence.
A family member went to their home after they failed to show up for church.
"We just want answers," Beth said, speaking on her parents’ anniversary to help keep their memory alive. She hopes doing so will convince someone to come forward with a clue that can help solve the case.
The Stephensons would be welcoming their second great-grandchild in October if they were still alive.
For Beth, knowing that child will grow up without ever knowing their great-grandparents is difficult. She struggles just as much with not knowing why someone would want to kill her parents.
She said her parents were upstanding members of the community and good people.
At the same church where they were married all those years ago, Union Baptist Church in Florence, Bill served for years as a deacon and Peggy played the organ.
The two also worked tirelessly with a truck stop ministry on Burlington Pike.
"We're still hearing stories of lives that they've touched," Beth said.
Boone County detectives have pursued hundreds of leads across several states, and they've also been working with the Vidocq Society , made up of volunteer crime experts who meet in Philadelphia.
The Kentucky crime lab that found a DNA match to the killer is now sharing evidence with a private lab the Vidocq Society utilizes in Philadelphia.
While those findings led to some answers, they also created new questions.
"Genetically we know who the person is, but there's no match," Beth said. "It makes no sense."
Beth clings to the hope that keeping the case in the public’s mind will lead to a break.
"I want people to realize that they were human beings and they didn't deserve what happened to them," Beth said. "We miss them so much, and we just want to know who did it and why."
