BOISE, Idaho (AP) — Idaho authorities made an arrest related to a "heinous" triple murder at a rural home in the Boise foothills and said they are working around the clock to identify the suspect or suspects in the deaths.
A 22-year-old Nampa man arrested in the case is accused of grand theft and forgery but not murder, the Ada County sheriff's office said Wednesday night in a statement.
Arrested earlier in the day at a Boise electronics store was Adam M. Dees, who is accused of three felony counts each of grand theft and forgery and a misdemeanor count of carrying a concealed weapon without a permit.
Deputies also seized a 2003 black Subaru Legacy with a gold panel that Dees was driving.
Two men and a woman were found dead Tuesday at the home. The victims' names have not yet been released.
"When I say this crime is heinous, that is probably an understatement," Sheriff Gary Raney told reporters Wednesday. "Somebody who violently, without cause, without any provocation that I know of, killed three innocent people. We are working 24 hours a day with everything we've got to put that person in jail."
Raney declined to speculate on a motive or say if anything was missing from the home. He said the victims were related, and the killings occurred sometime between Sunday evening and Tuesday morning.
"It's hard for me to fathom even after 31 years of law enforcement what could possibly motivate somebody to do to these people what they did," he said.
The sheriff declined to release many details about the investigation.
He said police were looking for suspects linked to a Subaru Legacy that was in the area when the killings occurred. He asked that anyone who saw it notify police.
The killings took place in what records say is a three-bedroom, three-bathroom home on about 20 acres with a total value of about $800,000. Authorities say the property has horses and other buildings.
He said police responded after a family member called Tuesday.
"I've probably not seen a bloodier or more violent murder occur," said Raney.
He said other law enforcement agencies were investigating, including the U.S. Marshals Service.
