A 19-year-old Suffolk man was found guilty Thursday in a failed plot to have a Western Tidewater Regional Jail correctional officer killed.

Raquan Darrell Knight, 19, was found guilty of two counts each of attempted capital murder by an inmate, attempted capital murder for hire and solicitation to commit murder, as well as one count of felony obstruction of justice.

Deputy Commonwealth’s Attorney Jim Wiser, who prosecuted the case, said Knight assaulted a correctional officer at the jail, which happened in June 2013 according to an online court information system. He was initially incarcerated on a robbery charge, according to the system. He has previously been found guilty in the robbery and the assault.

When Knight was indicted for the assault and battery, he apparently decided to try to have the officer killed, Wiser said.

On Oct. 11 and Oct. 15, Knight sent letters from the jail to a person he thought was a hitman, Wiser said.

“Fortunately, they were actually to our office and were received by an investigator in our office,” Wiser said. “Fortunately, nothing came of the attempted murder.”

Knight is set for sentencing on Jan. 26.
