As crews searched on Sunday, neighbors around the area tried to process what had happened.
"It's tragic," Jim Nagle said. "As a father and as a parent of three children, we have a son who's in between our daughters, you can only think the saddest thoughts possible and that's how I feel at the moment."
"It's just devastating," Lidiya Trusova said. "It's really sad to see something horrible occur right in front of your eyes."
Police do not believe that drugs or alcohol are a factor in the crash.
