According to Gardena police, Corey Delaine Stewart, met the victim last September on Tagged.com.
The two communicated for several weeks before planning to meet in person.
The victim says she only agreed to meet Stewart with the understanding that he was setting her up for a job interview.
But the meeting ended in violence, police say, when Stewart drove the victim to a residential neighborhood in Gardena and raped her at gunpoint.
The woman told investigators that she was unable to escape because the door handles inside the vehicle had been disabled.
Investigators say its possible that Stewart may have been working with an accomplice who uses the same car to commit similar attacks.
Anyone with information is urged to call Det. Michael Ross at (310) 217-9635.
