A New York mom vacationing in South Florida was expecting a healthy dose of sun, surf and fun. Imagine her surprise when her daughter unzipped a bag in their rental Nissan Rogue and found a rifle â€” a big rifle. Looking just like the ones real soldiers use. Horrified, she immediately called E-Z Rent-A-Car and then drove to the nearest police station. And there would be one more surprise: The AR-15 semiautomatic had been left behind by model Lauren Tannehill, the wife of Miami Dolphins quarterback Ryan Tannehill. â€œWe got out of the car, we were kind of freaked out,â€ Judith Fleissig recalls of the moment this month when she and her daughter found the weapon. â€œI didnâ€™t want to touch it.â€ Fleissig on Jan. 6 turned over the gun to the closest police station, following the rental companyâ€™s recommendation, officials said. Authorities conducted a review and determined it was legally owned and accidentally left behind. â€œThough dangerous if it would have landed in the wrong hands, itâ€™s not criminal,â€ Broward sheriff's spokeswoman Keyla ConcepciÃ³n said. â€œThey simply forgot it.â€ Lauren Tannehill, 26, is a model who was featured on HBO's â€œHard Knocks,â€ a reality sports documentary television series. The couple married in January 2012. A model in possession of an AR-15, the civilianâ€™s version of the militaryâ€™s M-16, may be incongruous to some. But it shouldnâ€™t surprise Lauren Tannehillâ€™s fans who view postings of her on Twitter. Pictures on the social media site show her and her husband shooting guns together. Ryan Tannehill, who is from Texas, has often talked about his hunting experiences. The Tannehills view this as a personal matter, according to a Dolphins spokesman Wednesday. The gun legally belongs to Ryan Tannehill, and the couple immediately called the rental car company to report a missing item, even though the couple didnâ€™t specify what was in the bag, a football league source said. According to a sheriffâ€™s report, Lauren Tannehill rented the white Nissan Rogue on Jan. 4 and returned it two hours later to the rental company, E-Z Rent-A-Car at Fort Lauderdale-Hollywood International Airport. Tannehill swapped it for a different car.
