A 51-year-old Oklahoma inmate accused of overdosing a woman and videotaping her death was found unresponsive Wednesday at his cell in the Delaware County Jail.
According to officials, Brian Edward Anderson was rushed to a Grove medical facility where he was declared dead that same day.
The incident is currently investigated by the Oklahoma State Bureau of Investigation.
An autopsy is expected to be performed by the state Medical Examiner’s Office to determine the Disney man’s cause of death.
He was accused of intentionally injecting 41-year-old Melissa Vermillion with a large dose of methamphetamine to stop her from testifying against him and his wife in court, reports said.
The late prisoner’s 43-year-old wife, Allie Beth Anderson, is also facing criminal charges related to Vermillion’s death that Anderson recorded, an arrest affidavit revealed.
Allie was a childhood friend of the victim since they were 8-year-olds. The couple knew Vermillion had a bad heart condition and taking meth would kill her.
