CHULA VISTA - A transient suspected in the stabbing death of his grandmother and uncle at an Otay Mesa mobile home park will undergo a mental competency examination before he's arraigned, a judge ruled Thursday.
Raymond Joseph Chatterfield, 29, was arrested about 7:30 p.m. Monday at a Jack in the Box restaurant in the 1100 block of 30th Street, roughly half a mile from the Beyer Way residence where Donna Chatterfield, 78, and Kenneth Chatterfield, 54, were found mortally wounded several hours earlier, according to San Diego police.
Officers responding to a 911 call about two injured people at Rancho Chula Vista mobile home park, a retirement-housing complex, found the victims shortly before 4 p.m. Monday, Lt. Paul Rorrison said. Both had suffered multiple stab wounds and died at the scene.
The motive for the slayings was unclear, though the suspect had a prior allegation of elder abuse involving his grandmother, who had obtained a restraining order against him, according to media reports. He also was rumored to be a "narcotics user," Rorrison told reporters.
Judge Patricia Garcia accepted a defense request that Raymond Chatterfield undergo a psychiatric evaluation.
She ordered the defendant to remain in custody without bail, pending a Jan. 7 arraignment.
