WAYNESVILLE, Mo. -- Pulaski County sheriff's deputies are investigating the death of a teenager.  William Posten, 18, died early Sunday morning at his family's home north of Richland on Missouri 133.

"It is not a common thing for someone to expire at a very early age like that from normal causes, however it has happened before," said Pulaskiy County Sheriff's Chief Deputy John Groves.

A family member found the teen's body.  When help arrived, it was too late to save him.

"A loss of a child, no matter what the circumstances, is traumatic, and when you start losing several people for various reasons, it all hits hard," said Groves.

The teen was last seen at a social gathering, but deputies would not say where or what kind of gathering.  Groves said there was no sign of trauma on Posten's body and said they do not suspect foul play.

"The scene itself didn't suggest any violence but, as you know, not everything is geared towards violence," Groves said.

Investigators are waiting on the toxicology report to tell them more.

"If there were any injections of any types of alcohol and/or narcotics of any other type of materials that may have been injected into his system, or to determine if it was nothing more than a simple death," Groves said.

Some autopsy results on Posten could be released this week, although toxicology tests at the state's crime labs typically take several weeks to complete.

Friends say the teen graduated from Richland High School in the spring of 2012.
