A Miami-Dade man was arrested Sunday after investigators linked him to an alleged armed kidnapping and robbery during a phone sale arranged through Facebook Marketplace, authorities said. Lazaro Nunez-Martinez, 31, faces charges including kidnapping with a weapon, grand theft and tampering, according to an arrest report. The allegations have not been proven in court. The victim told detectives that on Sept. 28, he contacted a seller through Facebook Marketplace to buy an iPhone. They met at the seller’s home, and the victim bought the phone, the report said. Weeks later, the seller offered to sell him more phones, and they arranged to meet outside the victim’s apartment building. At the meeting, the victim approached a BMW parked behind the building. When he opened the front passenger door, another person sitting in the back seat sat up and pointed a gun at his head, according to the report. The armed person ordered him in Spanish to get into the car and hand over his belongings. The victim tried to get out while the car was moving, but the suspects pulled him back inside, the report said. During the drive, he threw about $4,000 toward bushes, then escaped from the car and ran. One suspect stopped to retrieve the money before the suspects left, according to investigators. The victim gave detectives the seller’s phone number, which they used to identify Nunez-Martinez, the report said. Investigators also matched the BMW to him. Detectives later spotted him traveling on Florida’s Turnpike and arrested him after a traffic stop. The Miami-Dade Sheriff’s Office has designated public locations as safe havens for people meeting to buy or sell items online. The agency recommends using such locations for transactions.
