Funerals were held for Michael Logan Walker, 50, and Rachael Walker, 44, on Tuesday
An Oklahoma teen charged with two counts of first-degree murder for allegedly fatally shooting his parents believed they were Satan worshippers who were communicating with him telepathically, according to reports.
Online court records obtained by PEOPLE confirm the allegations against Michael Elijah “Eli” Walker, 19, of Edmund.
Police allege he shot both of his parents — Michael Logan Walker, 50, and Rachael Walker, 44 — on March 4 at their home in the Oklahoma City suburb of Edmond.
The Oklahoman reports the suspect’s brother told detectives Walker had allegedly said he killed their parents because he believed they worshipped the devil and were sending him messages telepathically.
According to the paper, Walker’s attorney, Derek Chance, plans to pursue a not guilty by reason of insanity defense, but first wants his client examined, saying he does not believe Walker is fit for trial.

“He’s very mentally ill, and even at this point it’s difficult even for us to get through to him in any of our meetings,” Chance told reporters.
Chance entered a not guilty plea on behalf of his client. PEOPLE’s attempts to reach him for comment were unsuccessful.
Funerals were held for the Walkers on Tuesday.
Michael Logan Walker’s sister, Maya Walker, made a statement to reporters following Tuesday’s services, saying, “Today, we honor two beautiful people.”
“My brother Michael is known as a highly-talented musician,” the statement adds. “His identity was founded in being a Christ follower, husband, father and friend. My sister-in-law, Rachel, was a champion for her family. She sought out the best in everyone and she loved people fierce. She took delight in the smallest details in life.”
The statement further alludes to the suspect’s mental health.
“We hope and pray for the best outcome for this tragedy and for Eli, my nephew, to get the best care possible,” said Walker.
