Deputies have arrested and charged a 16-year-old after they say he shot and killed his foster mother and two siblings, according to KRON.

Investigators said they found Keven Wayne Adams, the alleged shooter, at the scene of the Oregon home where the homicides occurred.

Adams allegedly admitted he shot and killed the victims, according to KOIN.

His foster father, Robert Adams, reportedly placed a 911 call stating his wife, Donya Adams, his daughter, Amory Adams and foster daughter, Payshience Adams were all dead as a result of gunshot wounds, court papers revealed.

The teen had reportedly waited for his father to arrive home.

Deputies said the father was told by the teen to not go inside, but instead to call police.

The father ignored the alleged shooter’s command not to enter the home. Once inside, he found the three victims and said he saw a weapon on a bed “which was not where it should be,” court records quoted the father as saying.

Investigators believe Adams shot the victims multiple times and used a handgun to carry out the crimes.

A Facebook search revealed a page belonging to an Amory Adams, who studied at Umpqua Community College, a facility in Roseburg, Oregon. That is the same college in which a shooter killed 10 people and injured nine in 2015, KATU reported.

Court records indicate Payshience Adams is the suspect’s sister and younger than 14.

Deputies reportedly took the teen into custody without a confrontation.

Authorities have booked him into juvenile detention. He is charged with aggravated murder. The juvenile is being held without bond.
