WEST LINN, Ore. -- An 18-year-old West Linn man died in his sleep over the weekend and police want to know how and why.
Corey Patterson was hanging out with his friends Friday night and came home around 1 a.m., according to police. When his younger sister went him to wake him Saturday morning she was unable to.
The family called 9-1-1. Paramedics pronounced him dead.
Patterson's death was called "suspicious" by West Linn Police Department on Tuesday, but they have not found any evidence of foul play.
"It is suspicious in that he's a relatively healthy 18-year-old man. An 18-year-old young man typically doesn't just keel over," Sgt. Neil Hennelly said.
A toxicology report to determine Patterson's cause of death could take four to six weeks.
There has been an outpouring of support from Patterson's online social communities at Facebook and MySpace. A web page in his memory has nearly 300 members who offer condolence.
Patterson graduated from West Linn High School two weeks ago.
Police said they would continue to investigate his death.
