DELPHI, Ind. -- Friday marks a solemn day for people living in Delphi and across the state of Indiana. It's now been five months since the bodies of Liberty German and Abigail Williams were found and their killer is still out there.
14-year-old Libby and 13-year-old Abby went missing on February 13 while hiking along the Monon High Bridge. The girls were taking advantage of a warm, sunny day off from school to take some photos and enjoy the outdoors. It was a day that would change the small community they grew up in forever.
Searches began that evening when the girls didn't show back up at their agreed-upon meeting location to be picked up by family. They searched through the night, unable to find any trace of Libby and Abby.
The next morning, search crews found the girls' bodies on a piece of private property, less than a mile from where they were last seen alive.

In the five months since that day, Indiana State Police, the FBI and multiple other agencies across the state have spent countless hours investigating and interviewing witnesses and possible suspects.
Indiana State Police Sgt. Kim Riley said investigators have received over 18,000 tips and interviewed over 1,000 potential suspects. More than 20 people have been arrested on unrelated charges because of the case, but so far no one has been charged with Libby & Abby's murders.

The reward for information leading to the arrest of their killer has grown to over $230,000 since February, but so far that hasn't led to any arrests.
In light of the tragedy, the residents of Delphi have come together to support the girls' families and each other in ways one can only imagine.
A memorial softball tournament to raise money for a scholarship fund in memory of Libby and Abby is being held this weekend. The tournament will run from Friday through Sunday with all proceeds going to the scholarship fund.

The sports complex will consist of "a couple of softball fields and a park" and will feature areas where kids and their families can enjoy sports, the arts and each other.
Planning the park has become a source of comfort for both families, and they want to make it somewhere they can go to find peace and where the girls will be forever remembered in their community.
Libby captured the two key pieces of evidence that state police have released regarding the only suspect they have in the murders: An image of a man wearing a blue jacket with his hands in his pockets walking along the Monon High Bridge and an audio clip of a man's voice saying "down the hill." Police have not said whether they believe the same man is depicted in both pieces of evidence, but they have yet to identify who either person is.
