Five people, including a 10-year-old boy, are dead after an SUV driver going east apparently lost control of his car and crossed a Long Island Expressway median in Manorville—and then went airborne hitting two other vehicles. Many first responders called it one of the "worst" crashes they'd ever seen.

The crash occurred around 9:35 a.m. near Exit 68 on the LIE, and the Suffolk County police said that Carmelo Pinales, 26, was driving east in the Subaru Outback that barreled into the westbound lanes, hitting a Honda and a BMW. Suffolk County Chief of Detectives Gerard Gigante said, "It looks like the Outback went airborne, hit the top of the Honda — the Honda doesn’t have front-end damage, but has significant roof damage. And it appears the BMW and the Outback collided. The engine of the Outback was thrown several hundred feet into the woods. The car is pretty much destroyed. It’s broken up into numerous pieces."

Pinales and his sister Patricia Pinales, 27, were pronounced dead at the scene while his son Christopher Pinales, 10, died at Stony Brook University Hospital. Other occupants of the car, Winnifer Garcia, 21, and Patricia Pinales' three-year-old daughter, were hospitalized for non-life-threatening injuries.

The Honda's driver, Scott Martella, 29, was killed in the crash, while his fiancee, Shelbi Thurau, 29, was hospitalized for non-life-threatening injuries. Martella, a former aide to Governor Cuomo, was communications director for Suffolk County Executive Steve Bellone.

An occupant of the BMW, Isidore Adelson, 81, died from his injuries last night; the BMW's driver, Marvin Tenzer, 73, and passengers, Sandra Tenzer, 69, and Helen Adelson, were hospitalized for non-life-threatening injuries.

Christopher Pinales had turned 10 and the family was reportedly heading to a birthday celebration when the crash occurred.

Investigators are looking into whether Pinales was speeding. However, according to WABC 7, "Relatives of the Pinales' family say they believe an earlier accident left an oil spill, which contributed to the crash."

Governor Cuomo issued a statement, "I extend my deepest condolences to the family and friends of those lost in the accident that occurred on Sunday morning on the Long Island Expressway... I personally knew Scott Martella who was among those killed in the crash as he served in my administration for more than four years. Scott was a dedicated, beloved public servant who worked day in and day out to improve the lives of his fellow New Yorkers. Scott was always full of big ideas to help solve the toughest challenges of the day, and he was deeply respected for his strong work ethic, candor and fighting spirit. Long Island is a better place today because of his service and dedication to the community."
