"My pelvis is crushed," she said, describing her injuries which also include a broken arm, broken teeth and bruises and scratches all over her face and arms.

Beckman got those injuries after being hit by a car while she was riding a motorcycle at West 6th Avenue and Stuart Street in Denver.

Police say Beckham's friend, who was driving the motorcycle, had safely moved into another lane to avoid a stalled vehicle. Police add that the motorcycle was established in the lane when a car suddenly came from the right.

"A vehicle swerved from the far right lane, striking the motorcycle," said Denver Police Department spokeswoman Vicki Ferrari.

The car kept going.

"I can't believe it. I would never leave someone," Beckman said.

She says she didn't even see the car coming.

"I remember us slowing. Then I remember getting hit," she said. "I remember tumbling and being in the middle of the road watching traffic, thinking 'Oh my God, I'm going to die.'"

Instead, other drivers stopped in the street and helped the 44-year-old mother of three.

"Basically, [they] ran into the middle of the road, picked me out of traffic and moved me," she said.

Those good Samaritans included the driver of an SUV who accidently hit Beckman after she was suddenly thrown from the bike. Police did not charge that driver.

"There were good people there too and without them I wouldn't be here," Beckman said.

But a hospital stay with such serious injuries isn't cheap. Beckman's twin sister Heidi Dirkse-Graw is concerned about how the self-employed therapist will pay for the bill.

She says the driver of the car needs to be found, so that that person's insurance can cover the costs.

"If the person doesn't turn themselves in or if someone doesn't turn them in, she's not going to get the expenses paid," Dirkse-Graw said.

Police are continuing their investigation, but they have few clues.

"All we've gotten in the investigation is a very, very slight description of the vehicle," Ferrari said.

Investigators say the car that hit Beckman is a mid-sized to compact vehicle with damage on the driver's side and a missing driver's side mirror. They do not know the color, make or model.

"What we're asking for is the community's assistance in helping locate witnesses who saw the driver or the vehicle or both," Ferrari said. "We're hoping that somebody did see it and will come forward."

Visiting Colorado from her home in Oregon, Beckman is hopeful that maybe the driver will turn him or herself in.

"I'd imagine they're guilt-ridden," she said. "It would feel a lot better to come clean."
