When the Baldwin Park CHP arrived on the scene of the wreck they recognized Corsaro's photo and called the El Monte Police Department.
Corsaro was then transported to County USC for treatment of minor injuries from the wreck, according to police.
The 48-year-old was first reported missing on Tuesday morning.
Corsaro's husband discovered she was gone when he came home to a ransacked house whose front door had been left open.
"He got home at about 9:30 to 9:45 and found his home unlocked and it seemed like it had been ransacked. Everything was kind of thrown all over the house. The wife was no where to be found," said Det. Tim Siedentopp, Senior Det., El Monte Police Dept.
Detectives say several items had been taken from the home, along with the couple's white 2008 Toyota Avalon.
The license plates of the couple's cars had been switched.
"One of the cars was missing that was in the garage. The license plates that were on that car that is missing were on another vehicle that was still parked at the house. The plates that were on that vehicle parked at the house are also gone," said Det. Siedentopp.
Corsaro is also known as Joellyn McAtee. She was listed as a "missing person with suspicious circumstances," according to police.
