Authorities in Selkirk are continuing to investigate what caused a fatal wreck on Route 9W that killed 18-year-old Logan Penzabene of Coeymans.
Officials say that based on eye-witness statements and evidence at the scene -- the Oldsmobile driven by Penzabene crossed the double yellow line and collided head on with the tractor-trailer.
Analysis has shown that the truck did begin to slow down and try to avoid Penzabene, and speed does not appear to be a contributing factor into the crash.
Matthew Hamilton, the passenger of the car, is still in the Intensive Care Unit at Albany Medical Center Hospital in critical condition.
The driver of the tractor-trailer was not hurt in the crash.
