Five people were killed after a pickup truck slammed into a freight train.Authorities said they were attempting to pull over the driver of a Chevrolet Avalanche on Tuesday, but the driver fled and wasn't spotted again until Wednesday morning.Police in Sanford asked for assistance from the Seminole County Sheriff's Office. Deputies said they used a helicopter to capture video of the vehicle speeding down several roads at speeds approaching 74 mph before hitting the stopped train.Investigators said a deputy was near the railroad crossing and used stopsticks to slow it down, and just seconds later, the driver hit the crossing gates and five people died.Authorities with the Sheriff's Office said they were keeping a safe distance from the pickup truck at the time of the crash."It did not meet the criteria for a vehicle pursuit. A pursuit is the continued attempt to apprehend a vehicle," Seminole County Sheriff's Office spokesman Lt. Don Rufo said.
