GARDEN GROVE – A 22-year-old woman who reportedly fell out of a vehicle on the westbound 22 freeway Friday morning appears to have jumped out on her own, authorities said as a California Highway Patrol investigation continues and new details emerge.

A dispute inside the car possibly led the woman to jump out on her own, said Sgt. Chris Pendleton with the CHP.

Pendleton said the man inside the car was an acquaintance of the woman.

Witnesses began reporting the incident at 6:31 a.m. just east of Knott Street. CHP initially described the woman as a child.

CHP officer Nathan Logan said the woman appeared to have minor bruises.

Jonathan Ganley of Anaheim said he was driving his Land Rover with his wife and one-year-old when he saw the woman “flipping head over heels on the freeway.”

Ganley pulled over into the center divider emergency lane and ran across the freeway.

“…She was up and running. I caught up to her and tried to calm her down,” Ganley said.

Ganley called 911 and Orange County Fire Authority paramedics treated the woman.

CHP officers were questioning the driver of a Lexus GS 300 that pulled over about 100 feet down the freeway.

The incident is still under investigation.
