Oscar Mandujano-Quinonez, who also went by “Manny,” was arrested in the evening after going to a park believing he was going to meet a potential victim he had found online, according to a Riverside Police Department news release.

Mandujano-Quinonez is suspected of stealing the purses and personal belongings of multiple women he met through the dating website Plenty of Fish, the Los Angeles Times reported.

An investigation began in Riverside last month after the suspect took out a woman he encountered through the website. While inside his silver Saturn, Mandujano-Quinonez “created a ruse” in order to get the female victim out of the car, the release stated.

Once she exited, he allegedly sped away, with the woman’s belongings still inside the Saturn.

The investigation into the mid-November theft led investigators to a warrant that had been issued for Mandujano-Quinonez’s arrest in Moreno Valley for a similar incident over the summer, according to police.

Investigators also discovered that the suspect had listed a woman’s allegedly stolen property for sale online, the release stated.

Detectives searched Mandujano-Quinonez’s Perris residence and found evidence from multiple crimes, and they believe there is at least one other victim, police said.

“This is one of those things — women scorned,” Riverside police Detective Byron Adcox told the Times. “They just got pissed off. They did a lot of the legwork.”

Mandujano-Quinonez used his actual name and photograph on Plenty of Fish, which made it easier for his victims to report the crimes, according to the newspaper.

“He’s probably not the smartest guy,” the police detective told the Times. “I sat in on an interview with the guy. He admitted some stuff but denied others.”

According to Adcox, more women have come forward following news of Mandujano-Quinonez’s arrest.

The suspect was booked into the Robert Presley Detention Center on suspicion of grand theft, according to the release.

Anyone with information about the case is asked to contact Adcox at 951-235-7863.
