New details were released Monday about a deadly crash in Greene County last October that killed four people.
Investigators said the teenage driver and two of his passengers were "huffing" just before their sport utility vehicle crashed into a motorcycle.
Cullin Frazer, Benjamin Hardy and Byron Kerr, all 18 years old, as well as the motorcycle driver were killed.
Police said autopsies showed the teens were inhaling computer cleaning spray as they headed north on Interstate 79 near Washington Township.
State police said the teens' SUV crossed over the median and went into coming traffic, where it collided with the motorcycle.
Three other teenagers in the SUV and a passenger on the motorcycle were seriously injured in the crash.
