The San Bernardino County District Attorney's Office filed two additional charges against Mercedes Vanesa Guevera. Both new charges are for insurance fraud. She allegedly reported her car stolen following the hit-and-run and abandoned her car at the scene while it was on fire, officials said.
Investigators said Guevara drove through a red light at high speeds when she hit victim Maribel Gonzalez at a crosswalk on West Highland Avenue last Wednesday night.
They added that the suspect did not stop to render help.
Gonzalez was 8 months pregnant during the fatal crash. The unborn child also died.

Police said someone from another car picked up the suspect and drove away. Evidence from the disabled car help to identify Guevara as the suspect.
On Monday, Guevara, 31, was arrested and booked on two counts of manslaughter in the hit-and-run crash. She is due back in court Aug. 20.
Gonzalez's mother said the family is still waiting for the coroner to release the bodies so a funeral can be held. She is also waiting to learn the sex of her unborn grandchild.
"It was going to be a surprise. She told me to buy an outfit for a girl and a boy," she shared.
