Around 4:30 p.m., the driver of the lifted truck struck the pedestrian while making a left turn on a green light, according to Citrus Heights Police.
The woman did not have the right of way when she entered the crosswalk.
"Apparently he didn’t see her and took off and ran her over,” said Michael Morrow, a passerby who tried to help after the crash.
Paramedics tried to save the woman but she died at the scene.
The driver cooperated with officers and neither alcohol nor drugs were believed to be factors in the crash.
The police department anticipated the intersection to be closed for around five hours.
