Authorities have opened a homicide investigation into the death of a 37-year-old Lisle man who was missing for six years before his skeletal remains were found in March, prosecutors confirmed Monday.
DuPage County Coroner Richard Jorgensen said an autopsy determined Scott Arcaro died of a gunshot wound to the head. Two boys walking last spring through a wooded area near the 7900 block of Lemont Road in Woodridge found the victim's remains.
Arcaro, who went missing in February 2007, was identified through dental records, according to Jorgensen. The coroner declined to release additional information because of an ongoing investigation.
State's attorney spokesman Paul Darrah confirmed there is an "active homicide investigation" into Arcaro's death but would not release further details. Woodridge Deputy Chief Tom Stefanson would not comment on the nature of the case but said police have "come up with some avenues that we're running down in our investigation."
Arcaro last lived on the 2700 block of Weeping Willow Drive near Benedictine University in Lisle. His girlfriend, Nicole Goyette of Downers Grove, said in 2007 that she last heard from him when he sent a text message around 3 p.m. on the day he went missing.
At the time, Goyette said Arcaro kept in frequent contact with her and she didn't believe he would disappear on his own.
"Maybe he trusted the wrong people," she said in 2007.
Goyette could not be reached Monday, and a member of Arcaro's immediate family declined to comment.
Authorities said anyone with information on the case should call Woodridge police at (630) 719-4764.
