ROSEBURG, Ore. -- There are new details Thursday morning in a triple homicide in Lookingglass, an unincorporated area southwest of Roseburg.
A woman who knows the 16-year-old suspect says she picked up on some red flags.
Kevin Adams is accused of killing his own sister, foster mom, and foster sister.
Brenda, who asked to keep her last name anonymous, says her younger son and Kevin played together all the time in elementary school, but there were problems.
She says Kevin was prone to violent temper tantrums.
“He would have outbursts, Kevin would, if he didn’t get his way,” she said in a phone interview. “He would throw things, get violent."
“He would have so many outbursts that I couldn't have him coming over anymore. It was too much to handle.”
Brenda says she didn't see signs of abuse in the family, nothing that would lead to this.
Douglas County deputies say Kevin's foster father wasn't home when the shootings occurred.
Court documents say he came home and found his son outside the home telling him to call 911 and not to go inside the house.
The victims have been confirmed as 55-year-old Donya Adams, 26-year-old Amory Adams, and 10-year-old Payshience Adams.
