The 72-year-old woman, who asked to remain anonymous, said she was in her car on Misty River Road when a man approached her.
"He walked up and just grabbed me out of my truck," she said. "I fell onto the ground, on the grass."
She said the carjacker, identified as Collin Welch, drove off before crashing into a home across the street.
A neighbor took cellphone video of the aftermath.
One person can be heard screaming, "let's move away from him, let's move away from him."
"He backed out of the driveway in my truck," the woman said. "The keys were still in the ignition because I [had] just got home. When he backed out of the driveway, he backed up into that house."
Welch was arrested shortly after.
According to records, Welch has been charged with aggravated robbery.
The victim's car has since been returned. While there is damage to the front and back, she says she's just happy the outcome wasn't any worse.
"I'm blessed he didn't have a weapon or anything," she said.
She also wants to warn others to be careful, even outside your own home.
"Watch your surrounding and be careful," she said. "I'm fine now. I calmed down. My adrenaline was up, my blood pressure [was up]. EMS came and checked me out."
Welch has not made bond and is still behind bars.
