The days just don’t get easier for Betsy Houtz.

“So often I’ll hear her say mom, mom,” she told us with tears in her eyes. “I’ll look everywhere and she’s not here.”

Five years ago she lost a friend, someone who could always make her smile, she lost her daughter, Sherry Houtz.

“It’s just not fair,” Betsy told us. “I can’t let go. People tell me it will be better, you’ll get over it, but you can’t get over losing a child.”

Betsy’s world turned upside down February 12, 2013.

Sherry was walking along I-99 when she was struck by a car. The suspect took off.

“She hit the front passenger bumper, flew over the car and into the air,” Betsy explained. “She went down really hard and the car never stopped.”

There’s even a cross that still sits on the side of the highway where Sherry was hit and killed. It’s a reminder that she’ll never be forgotten and hope that a suspect will soon come forward.

“We believe whoever the driver of the vehicle was that evening, they have the information, or somebody that’s close to them may have that info and hopefully they come forward and do the right thing,” Trooper Jeff Petucci, from Pennsylvania State Police, said.

To this day police are still investigating as loved ones continue to look for closure and an answer to one simple question, why?

“I don’t know how the person keeps going by living and looking at himself in the mirror,” Betsy told us. “I just don’t understand.”

For now, Betsy holds close to the memories she still has of Sherry, like the butterfly necklace she wears with her daughter’s ashes. It’s a way to keep her close to her heart.
