FONTANA, Calif.—A California inmate charged with the stabbing death of a California prison guard has been ruled mentally competent.

San Bernardino County prosecutors say 35-year-old Jon Christopher Blaylock killed Chino prison officer Manuel Gonzalez in January 2005.

The 44-year-old Department of Corrections guard had allowed Blaylock out of his cell in an attempt to quell racial tensions inside the prison just before he was stabbed.

The Inland Valley Daily Bulletin ( http://bit.ly/SPim0U) says some doctors testified that Blaylock believes he's a member of Dutch royalty and prison guards are out to kill him.

Others testified that he's not delusional and is simply an inmate who has learned to manipulate the system by faking medical issues to delay court proceedings.

The jury decided on Wednesday that Blaylock is mentally competent and criminal proceedings were reinstated.

Trial resumes on Jan. 11.
