Erika Aguilar was crossing Main Avenue in Clifton two days after Christmas to meet up with friends when a silver car plowed into the 26-year-old.

She was four months pregnant at the time and, miraculously, her unborn child survived unharmed. But she suffered extensive and traumatic injuries.

The driver stopped, got out and looked at Aguilar before fleeing the scene. The hit-and-run case remains unsolved and Aguilar's mother Ana is hoping that justice will ultimately prevail.

"Just turn yourself in," Ana Aguilar said Friday as her daughter was preparing to be discharged from a rehab facility a month after the crash. "How do you leave a pregnant woman out on the street and keep going? Have a conscience and own up to what you did."

The crash occurred at 9 p.m. on Dec. 27 near South Parkway in Clifton, Passaic County Assistant Prosecutor John Statuto has said.

Aguilar, of Garfield, was on her way to join friends at a local pub where 50 cent wings were being served, her mother said. A witness described the hit-and-run driver as heavy set.

"He got out of the car, looked at her and took off," Ana Aguilar said.

Erika Aguilar suffered extensive injuries, including fractures to her mid-section, her right leg and her left hand. She also suffered deep cuts to her face, head and scalp, said her mother, who is a registered nurse.

First-responders found Aguilar lying in the road. They brought her in stable condition to St. Joseph's Regional Medical Center in Paterson where she remained for several days.

"The baby is fine," Ana Aguilar said. "The pregnancy is fine. We had a miracle."

Erika Aguilar, who also has an 8-year-old son, was eventually transferred to Kessler Rehabilitation Center in Saddle Brook.

While Erika has insurance through her job as a dental assistant, her mother has set up a GoFundMe page in an effort to raise $50,000 to pay for deductibles and medical supplies.

"She has a back brace and she's going to need a cane and a walker along with a chair for the shower," her mother said, adding that her daughter may require plastic surgery.

"We have to see how everything heals," Ana Aguilar said. "I've taken six weeks off from work to be with her, to get her walking and functioning."

Erika Aguilar, who injured her dominant hand, hopes to get back to her job as a dental assistant in Little Falls as soon as she is healed, her mother said.

The hit-and-run is not something her daughter talks about, mostly because she "doesn't remember much," her mother said.

"She cries. She asks, 'Why did this happen to me? What did I do to deserve it?' Ana said. "I tell her everything is going to be OK."

The Passaic County Prosecutor's Office asks anyone with information about the hit-and-run to call its tips line at 1-877-370-PCPO or email tips@passaiccountynj.org.
