The families of the two girls killed in Delphi in February are hoping national attention on an upcoming "Dr. Oz" show will prompt new leads in the unsolved case.

INDIANAPOLIS, Ind. (WTHR) - The families of the two girls killed in Delphi in February are hoping national attention on an upcoming "Dr. Oz" show will prompt new leads in the unsolved case.

After the satellite taping from the WTHR studios in Indianapolis, the families of Libby German and Abby Williams shared openly about the heartache they feel as police search for the killer. Libby German's grandfather says he talks with police at least once a week, but says he doesn't know much more than the public.

"I want to protect the integrity of the investigation. The most important thing - I want to catch this guy," said Mike Patty.

Libby German's grandmother believes investigators are making progress in identifying the man who murdered the girls.

"I have faith in them. I know they're getting rid of tips because we've gotten calls on different things," said Becky Patty.

The mother of Abby Williams was asked if the suspect's photo or voice recorded on the girl's cell phone were familiar.

"We all came in to hear the audio. And, when we saw the sketch, we all held our breath, but at the same time, you hope you don't. You hope this isn't your neighbor," said Anna Williams.

Abby Williams and Libby German would have started high school this fall.

"The first day was tough. This was supposed to be their first day of high school. Libby was going to walk into school with her sister that day. She didn't go. That was a rough day," said Becky Patty.

The families talked lovingly about the girls.



"(Libby) was special. I know most people say their kids are special. She stuck up for kids. She tried to lead by example," said Becky Patty.



Libby's grandfather remembered how the girls enjoyed hosting sleep-overs.

"It would be nothing to have six girls at the house, camping out until they hear a raccoon. They had pool parties, they would be over there swimming. Very social little butterfly," said Mike Patty.

Anna Williams revealed that the nursing home where she works is going to sponsor 100 Christmas boxes for children around the world, a tradition that Abby enjoyed when she was alive.

"The givingness that (Abby) had inside her is going to continue. This year it'll be 100 (boxes). Next year we're going to go for 200," said Anna Williams.

Libby German's grandfather says he has several theories about the man who killed the teen girls in Delphi.

"I think he was a predator. He isolated those girls on that bridge and took advantage of their innocence. And simply murdered them. That's a fact," said Mike Patty.

"I can't fathom who would do something like this or who it would be," said Becky Patty.

"I try to let the investigators do their job. If I spend too much time in my head and heart thinking about what happened out there that day, none of us would get out of bed," said Anna Williams. "I need to say, God's got this and so do the police. And, we're going to do what we can which is work on our park and our ballfield and we're going to keep moving our families forward, inch by inch."

The families hope their appearance on a future Dr. Oz show will raise awareness about the case.

"I'm hoping that there's going to be people who haven't heard about the girls, who see this. I hope the right person sees this who says, I know that person," said Becky Patty.

"If you know, if you have the slightest hint that you know, turn them in."

"Mother to mother. Sister to sister. Daughter to daughter. We just ask that you do the right thing. Do the right thing for our girls. And to keep this from happening to the next family," said Anna Williams.
