Court officials say 39-year-old Joshua Aikens was convicted Friday of first-degree murder for his role in the death of Robert Quenton McCullough in the fall of 2020.

Aikens was sentenced to life in prison with the possibility of parole.

Under current Tennessee sentencing law, a life sentence with the possibility of parole is 60 years.

If Aikens, while in prison, conforms his behavior accordingly, then he will be eligible for up to 15% ‘good behavior’ credit, meaning that he could be released as early as 51 years from the date of his initial arrest.

Aikens will receive credit toward his 60-year sentence for the time he has already served in jail since his arrest.

Robert Quenton McCullough was last seen on October 7, 2020, and was reported missing by his mother on October 17, 2020. After a lengthy missing person investigation by multiple agencies, McCullough’s body was discovered in an abandoned trailer in Oakdale, Tennessee on December 2, 2020, by the Roane County Sheriff’s Office after a tip led them to the trailer.

Three individuals: Joshua Aikens, Shane Parks, and Nicholas Holloway, were charged with the murder of McCullough.

The three have all been in custody since their arrest.

Parks and Holloway are awaiting trial.

The murder of Quenton McCullough was investigated by the Roane County Sheriff’s Office with the assistance of the Rockwood Police Department and the Morgan County Sheriff’s Department.

The multi-agency cooperation, along with the assistance of the Knox County Regional Forensic Center and the Forensic Anthropology Team on this case, was instrumental in the successful prosecution of Joshua Aikens.

The case was prosecuted for District Attorney General Russell Johnson’s Office by ADA Bob Edwards and ADA Jonathan Edwards. They were assisted by Victim Witness Coordinator Tami Bailey.

Aikens was defended by Attorney Tracey Williams.
