The State - News from Feb. 12, 1988

A man charged with three claw-hammer murders and an attempted murder told a psychiatrist he wanted to kill doctors because he believed they planted threatening voices in his head, Sacramento Superior Court records reveal. Jeffrey G. Jones is awaiting court proceedings to determine if he is mentally competent to stand trial. He is charged with the 1985 slayings of a physician at the University Medical Center in Sacramento, a physics lecturer at the University of California, Davis, and a man in a Sutter’s Fort restroom. He is also accused of trying to kill a third-year medical student at the medical center. A psychiatrist for the defense, Dr. Captane Thomson, said in a report to the court that Jones believed a doctor had implanted a device in his head that made him hear voices that told him to kill and made threats to him like, “We’re going to kill you.”
