    The man accused of stabbing his mother and sister to death in their Rancho Penasquitos home was determined mentally incompetent to stand trial, a judge ruled Wednesday morning.

    Brian Rockwell Williams, 24, was arrested shortly after police found the bodies of SDPD detective Donna and her daughter Briana "Bree" Williams in the house. Brian was calmly sitting next to his dead sister in front of the home when police arrived. He did not resist arrest.

    Police sources and family members acknowledged that Brian suffers from schizophrenia. On June 30, officers were called out to the family home after Brian caused a disturbance.

    Schizophrenia is a mental illness that can lead to violence if not treated with medications, according to psychiatrist Clark Smith, M.D.

    Donna Williams, a San Diego police detective, and daughter Bree Williams, a Mt. Carmel High graduate and softball standout, were remembered Thursday during a service. They were fatally stabbed in their Rancho Penasquitos home on July 18.

    "It affects the way people think, often causing paranoia, delusions and even hallucinations," said Dr. Smith in an earlier NBCSanDiego.com report.

    Yet family members and friends did not expect that Brian would ever murder his mother and sister. Many even described him as gentle and friendly, despite needing help for his mental condition.

    "He's never been violent, he's never been upset to this degree," Brother Howard Williams III told NBCSanDiego in July.

    Brian previously pleaded not guilty to the murders. The judge in the case suspended any criminal proceedings against Williams.
