According to The San Diego News, at around 9:20 am local time the victim was dashing across a crosswalk when she was struck by a Subaru Outback.
Witnesses say the woman tried to stop when she realized the oncoming vehicle, driven by a 67-year-old man, was not slowing down but tripped and fell into the car. She was rushed to the emergency room with extensive head trauma but doctors were not able to save her.
Police are questioning the man that hit her but neither the name of the victim nor the driver has been released to the public. Despite this, the hashtag #RIPTwiFanG has sprung up on Twitter to start funds for a memorial service.
