LOOKINGGLASS — A foster son is accused of shooting to death three members of his foster family in this rural community about 10 miles southwest of Roseburg.

Shortly before 8:45 p.m., Robert Adams dialed 911 to report that his foster son, 16-year-old Kevin Wayne Adams, had murdered his family in the 400 block of Whispering Pines Way.

Deputies from the Douglas County Sheriff's Office responded to the scene and located and detained the teenage suspect.

Inside the residence, police found three deceased victims. Court documents identify the victims as 55-year-old Donya Adams, Robert Adams' wife; 26-year-old Amory Adams, the Adams' daughter; and 10-year-old Payshience "Tia" Adams, the Adams' foster daughter and Kevin Adams' biological sister. The Douglas County Medical Examiner's Office and members of the Douglas County Major Crimes Team later confirmed the victims' identities.

In an interview with police, Robert Adams said he left home at approximately 6:30 p.m. Tuesday and returned to the home shortly before making the 911 call. When he arrived home, he found his foster son outside who said to call the police, but told him not to go inside.

Robert Adams entered the house and found his three family members had been shot and killed. On his bed, Robert Adams found a handgun which was not where the firearm was supposed to be, according to court documents.

Kevin Adams later told police that he shot the victims multiple times after his foster father left the house and then waited outside for his return.

Kevin Adams was arrested and lodged at the Douglas County Juvenile Detention Facility. Aggravated murder can be punishable by death or life imprisonment, and a 16-year-old can be charged as an adult under Oregon's Measure 11 felony guidelines.

According to Brad O’Dell, a spokesman with the Douglas County Sheriff’s Office, the Douglas County Major Crimes Team was activated and on scene. The team consists of detectives and investigators from the sheriff’s office, the Roseburg Police Department, the Oregon State Police and the Douglas County District Attorney’s Office.

Because of the tragedy, two Douglas County Department of Motor Vehicle offices that Robert Adams managed were closed Wednesday, according to a department spokesman. While both offices are expected to reopen on Thursday, Oregon Department of Transportation Director Matthew Garrett said in an all-staff email that entire department was in mourning.

"I urge you to be sensitive to those touched by this tragedy, which prompted us to refrain from opening the DMV offices in Roseburg and Canyonville at least for Wednesday. I hope I speak for all of us when I say that all of us at ODOT are mourning," he wrote.
