Police have arrested the mother of two Oregon brothers who allegedly lured a 16-year-old boy to the woods and beat him to death.

The Olympian reports that Kindra Rose Adamson, 43, was arrested Tuesday night and charged with first-degree rendering criminal assistance. In a statement, the Lewis County Sheriff’s Office said her arrest was based on “actions and knowledge of the crime after the homicide, but prior to the arrest of the two suspects.”

The “suspects” mentioned in the press release are Jonathan R. Adamson, 21, and Benito S. Marquez, 16, who are accused of murdering Ben Eastman late last month. As CrimeOnline previously reported, text messages indicate Eastman had met with Marquez for a camping trip when he disappeared. The missing teen’s body was reportedly found in a shallow grave located on the property of the suspects’ grandparents in Randle.

The pair is accused of sexually assaulting Eastman with a stick and beating him with rocks. KOMO reports that the older brother estimated he kicked Eastman approximately 100 times during the barbaric attack. An autopsy indicated that the teen died from blunt force trauma to the head and had significant injuries to his head and torso.

Johnathan and Marquez (who will be tried as an adult) were charged with murder, first-degree rape, tampering with physical evidence, and unlawful disposal of remains. They are each being held on $10 million bail.

Meanwhile, Lewis County Prosecutor Jonathan Meyer has alleged that the mother knew about the teen’s slaying shortly after it happened and delayed authorities in their investigation. She’s scheduled to appear in court on Wednesday.

The victim’s father told KOMO that it was “about time” the mother was arrested.

“I couldn’t imagine she didn’t know anything,” he said.
