She said she used OfferUp to sell many of her old things.

“It’s scary. It’s scary,” she said in an interview with Eyewitness News. “I could have lost my life.”

The woman said, recently, she sold a radar detector on the app, purchased by the couple who reportedly came to her house to check it out.

According to the victim, a baby slept in the backseat of the vehicle while the man and woman looked over the radar device, when all of the sudden, the man took off with the merchandise.

While she said her security camera got a clear picture of the incident, it turns out the woman wasn’t the only victim in the scam:

The couple allegedly robbed one unsuspecting seller earlier, going on to rob three others the same day — including a man at a Shell station off Eastex Parkway, who reportedly lost his iPhone to the couple.
