Gerald's Smith's dinner was on the stove waiting for him to get home Wednesday around 4:30, as the 82-year-old retired real estate agent sat at a stop sign at Northeast First Street in his Buick SUV. Roger Wittenberns, 60, the multimillionaire founder of the Lady of America fitness club chain, and his longtime girlfriend Patty Ann McQuiggin, 61, spent the afternoon eating and drinking in downtown Delray Beach. They left in separate yellow luxury cars — he in a Lamborghini, she in a Porsche. They were speeding on Federal Highway, police said. As Smith headed west to cross Federal Highway, the Lamborghini crashed into his Buick Enclave, killing him, police said. Speed and alcohol are both being considered as factors in the crash, said Delray Beach Police spokeswoman Dani Moschella. Police said it was Wittenberns who told them he had been drinking in the afternoon. He suffered critical injuries in the crash and remains hospitalized at Delray Medical Center. Police haven't determined exactly how fast Wittenberns was driving. No one has been charged in the crash, but police say the investigation continues.
