SAN BERNARDINO A 28-year-old Barstow woman walking on State Route 210 was struck by a car and killed Tuesday night.

Vanessa Marie Bravo was walking westbound on a dimly-lit portion of the freeway when a motorist driving westbound in the second lane hit her, according to a California Highway Patrol news release.

The vehicle was approaching Waterman Avenue at an undetermined speed when the incident occurred about 9:37 p.m.

"It's a tragic series of events. From our family we know she led a very, very hard life," Bravo's uncle, Edmond Bravo, said.

According to Bravo, she was estranged from her family and had addiction problems. Based on obscenities she wrote on her Facebook page a few hours before the accident, he suspects she had gone into a "downward spiral." She was also the mother of six children and may have possibly been pregnant with a seventh, he said.

A 911 call made just prior to the collision indicated there was a female with dark clothing running in the roadway on Interstate 210 and the Waterman Avenue overpass. Following the collision the first car involved, a 2006 Ford, was rear-ended by a second motorist in a Dodge.

Bravo sustained major injuries and was treated on-scene until being taken to St. Bernardino Medical Center in San Bernardino. Shortly after arriving at the hospital at 10:21 p.m. she was pronounced dead by hospital staff, according to a news release from the San Bernardino County Coroner.

The driver of the Ford suffered moderate injuries and was taken to Loma Linda University Medical Center. A passenger from the Ford was also taken to Loma Linda University Medical Center with minor injuries.

The driver of the Dodge suffered minor injuries and was transported to Arrowhead Regional Medical Center.

The collision is under investigation. Witnesses are asked to call the CHP at 909-383-4247.
