A man shot and killed inside a Florida Publix this weekend was buying lottery tickets before the shooting occurred, police say. The shooting stemmed from an argument in the checkout line of a Publix on Saturday evening in the upscale neighborhood of Coral Gables.According to NBC Miami, the shooting left 50-year-old Franklyn Jose Pineyro dead and 51-year-old Osmel Lugo-Gutierrez facing a second-degree murder charge.An arrest report states Pineyro was in the customer service line and buying lottery tickets when Lugo-Gutierrez approached him from behind.The report states Pineyro lunged at Lugo-Gutierrez with his arm outstretched, but he lost his balance and stumbled. Once Pineyro regained his balance, the report states he took a step in Lugo-Gutierrez’s direction. That’s when Lugo-Gutierrez allegedly lifted the front of his shirt, pulled a pistol from his waistband and shot Pineyro once in the chest, killing him.Lugo-Gutierrez was booked into Miami-Dade’s jail, where he is being held without bond.
