DERRY TOWNSHIP (KDKA) — Seven years after her death, a Westmoreland County woman’s murder remains unsolved.

Samantha Lang’s family says they want answers, and now there’s extra incentive for witnesses to come forward as her family is offering more money as a reward to find out who is responsible for her death.

When Rachel Miller describes her sister, it’s nothing but happiness.

“She was amazing. Her smile lit up a room,” said Miller.

But when she describes how her sister died, it’s nothing but horror.

“It was brutal,” Miller said. “He slit my baby sister’s throat from ear to ear.”

On March 27, 2007, 22-year-old Samantha Lang was murdered inside her home in Derry Township. It’s been seven years without a capture and conviction.

“You get angrier, especially since her killer is walking the streets,” said Miller.

In an effort to keep what happened to Samantha in the public eye, more banners and signs are up as is the total reward money.

“It’s $50,000,” said Miller. “It’s a lot of money to do a lot with. All you have to do is come forward.”

The state police continue the investigation and they have lots of clues.

“We’re just hoping something pops up that were able to focus our investigation on a particular individual,” said Trooper Steve Limani, of Pennsylvania State Police.

Until that happens, Miller is begging everyone to not forget what happened to her sister.

“We’re asking someone to come forward. It’s time,” she says.

If you have any information about the murder of Samantha Lang, the State Police want to hear from you.

Meanwhile, her family says they’ll never forget and will continue to look for her killer.
