Fourth Man Found Guilty of Murdering Marine, Wife in 2008

The fourth man accused of the 2008 murders of a U.S. Marine Sergeant and his wife in their Murrieta home was found guilty today of two counts of first-degree murder and additional crimes.

Kesaun Kedron Sykes, 27, of Fallbrook also was found guilty under the special circumstances of murder during the commission of a robbery, during the commission of a burglary, rape by instrument, and multiple murders.

Jurors deliberated less than two hours before reaching the verdicts in Riverside County Superior Court.

According to a news release from the District Attorney's Office, the trial now moves to the penalty phase, during which the same jurors will hear testimony and decide if Sykes should be sentenced to death or life in prison without the possibility of parole.

U.S. Marine Sgt. Jan Pietrzak, 24, and his wife Quiana Jenkins-Pietrzak, 26, were found murdered in their home in the unincorporated area of Winchester/French Valley, near Murrieta. They were found bound and had been shot in the head.

Also found guilty in previous trials were Kevin Cox, Emrys John and Tyrone Miller. According to the DA's Office, Cox, John and Miller had all worked with Sgt. Pietrzak while stationed at Camp Pendleton.
