Rangers who responded to the scene did not find evidence that vehicle had traveled down the levee or that one was in the river.
“There were some visible tire tracks in the park at the site of the crash at the top of the levee,” Hess said. “We could not tell for sure if it was from the same car that was involved in the crash.”
He noted that there were no known witnesses to the crash or 911 calls reporting the incident.
On Jan. 4, Christon’s father reported him as missing to Trotwood police.
“Once it was discovered that the now-missing man was the same person that was involved in the crash, we decided to re-double our efforts to locate the car in the river,” Hess said.
On Jan. 5, Ohio State Highway Patrol Traffic Crash Reconstruction team members went out to the scene. MetroParks rangers worked with Vandalia police to use a drone to search the river from above and Wright-Patterson Air Force Base Water Rescue used an underwater drone and sonar-equipped boat.
“The car was not found, and again, there was no evidence to believe the car was in the river,” Hess said.
It is not clear how long the car was in the river. An investigation into Christon’s disappearance showed that his phone stopped operating on Dec. 31, leading investigators to believe that’s when the incident took place.
