The owner of a Staten Island construction company pulled a revolver on a former business partner and demanded the man hand over his dentures, police sources tell the Staten Island Advance. Jospeh Nativo, the 47-year-old owner of Atec Construction, also allegedly demanded $1,200 in cash, two cell phones, a Bluetooth wireless device and the jacket worn by his victim, 40-year-old Gennario Sibbio. The incident took place in Nativo's office, but he says Sibbio wasn't a business partner but rather a former employee who stole from his company: "He owes me over $27,000 from the company. I took his phones. I took his car. Everything that I gave him, I took it. I paid for his new teeth to be put in... I told him to leave the company. I asked for my teeth back." His lawyer says the allegations are being exaggerated by the toothless Sibbio to retaliate against his former boss. And Nativo, who was arraigned Monday on a charge of first-degree robbery, denies pulling a gun: "We yelled and we argued, don't get me wrong. But in the end, those teeth belonged to me."
