GREENSBORO, N.C. -- All it took was one second to end the lives of five people and forever change countless others, like PD Ostwalt.

"A bad dream," he says.

Ostwalt is remembering a deadly car crash in Greensboro about two weeks ago. His graddaughter Stephanie Warshauer, 32 was one of the people who lost their lives.

"She'd come by 2,3 4 times a week," Ostwalt says, remembering the frequent visits with his granddaughter.

Warshauer and her friend Allie Bolick, 29, were riding into the intersection of Battleground Avenue and New Garden Road earlier this month when police say another car ran a red light and smashed into them. They say that car was a stolen vehicle and was speeding away from a Sheriff's deputy when it crashed.

The three people in the suspect car, Lee Manuel, 42; Theresa Monique Kingcade, 34, and Bruce Wayne Hunt, 30, were also killed.

In the instant Stephanie was killed, gone too were the moments her grandfather would look forward to.

"She'd come over and have dinner with me," he explains. "Every now and then she'd play on the piano a little bit."

Now the piano sits with him at home, a silent reminder that Stephanie won't be back to play it.

"It's unreal," he says.

P.D. shares his pain because he doesn't want this to happen to anyone else. He's already been through a lot, losing his wife and daughter in the past few years. He wasn't expecting to outlive his granddaughter.

"I've been very fortunate in life," he tells. "All three of them were just beautiful people inside and out."

He says Stephanie's impact on everyone she knew became clear to him at her services.

"The number of people who showed up at her service - I bet there was 200 young people. I didn't know so many young people knew her. Very considerate, kind."

He now keeps Stephanie's picture next to his favorite chair, close to his heart, facing her sister's portrait across the room.

"I let her look at her sister and her sister can look at her."

Some solace for a grandpa who knows his granddaughter didn't deserve to die the way she did.

"The sweetest granddaughter you'd ever want," he says.

The crash itself has called into question police chase policies in Guilford County. The Sheriff's Office tells us county attorneys will be meeting with an attorney for the victims' families Tuesday morning to discuss policies.
