Lancaster police are investigating the unexplained death of a 17-year-old youth who was found dead in his parked car on the street Sunday morning, with the engine running.
The body of Kyle T. Stablewski, of Broadway in Lancaster, was discovered at about 8:30 a.m., after a neighbor on Gale Drive noticed the vehicle running.
An autopsy Monday morning in the Erie County medical examiner's office found possible signs of carbon monoxide in the youth's system, police said, but no definitive cause of death was given pending further toxicology results.
Detectives have learned that Kyle attended a house party nearby on Gale Drive until early Sunday morning.
"So far, the investigation shows he left the house party at 1 or 2 in the morning, and he went to his car," Lancaster police Capt. Timothy Murphy said Monday. "We're not sure what happened then. It appears he may have fallen asleep after he started his car."
Investigators plan to check the youth's vehicle for possible carbon monoxide leaks. They also plan to interview everyone who attended the house party, where detectives say there may have been some underage drinking.
The investigation is being headed by Detectives Leon Robak and Donald Lynch, along with school resource officer Keith Kerl.
Lancaster police are asking anyone with information about the case to call the Detective Bureau at 683-3120.
Lancaster School Board members began their meeting Monday night with a moment of silence for Kyle.
Spokeswoman Patricia Burgio said flags were flown at half-staff in the district Monday.
"A counseling team came in and was available to students," she said.
Members of the Lancaster Town Board ended their meeting Monday in Kyle's memory.
