TULSA, Oklahoma - The family of a woman killed on New Year's Day is pleading for the person responsible to come forward.

Christina Bradshaw was driving to work when she was the victim of a deadly hit-and-run.

Police say the man who hit her was stealing a trailer.

Christina Bradshaw's family says she was one of the friendliest, sweetest women they know.

She died Wednesday afternoon and police are still looking for the man who did it.

"She'd have that big ol' smile on her face and she could brighten up your day within a heartbeat," said Angela King, Bradshaw's sister.

She has nothing but fond memories of her younger sister.

"I envied her," said King. "I really did. I looked up to my younger sister. She had a heart of gold and she didn't deserve what had happened to her.

Christina Bradshaw died New Year's Day when her car was hit by a truck speeding through the neighborhood at 9th and Richmond.

Police say the driver of the truck that hit her had just tried to steal a trailer when he suddenly took off and slammed into Bradshaw's car.

A day later, and her friends have come to try and make sense of it all.

"It's kind of unbelievable; always happens to the good ones," said Dave Jackson, and friend of Bradshaw.

Bradshaw was known for her infectious smile. She didn't have any children of her own, but she took her nephews and nieces under her wing and treated them like royalty.

Justin Pigeon, her nephew, said, "Anytime I needed somebody to talk to or somebody to hang out with, I knew that I could call her at any moment. And it didn't matter where she was, she'd make it happen to where she could be with me and hang out with me and talk with me."

Bradshaw worked a number of jobs.

She was a part-time clerk at Fiesta Mart at 11th and New Haven, where a collection is now being accepted to help her family.

"She was the most dependable, loyal employee that I could ever ask for," said store manager Joe Waggnor.

She was also known for taking care of the elderly. She was a caregiver and worked with hospice patients, always there, always smiling.

"She was a wonderful, wonderful person," King said. "She had a heart of gold. She'd give her clothes off of her back to help somebody else.

After hitting Bradshaw's car the suspect ran away. Police describe the man as in his late-20s or early-30s with a buzz haircut.

Police say they are running a search warrant on the stolen truck Friday to find finger prints and DNA.

Photo lineups will be shown to witnesses as well.
