Investigators determined the man’s 33-year-old live-in domestic partner was responsible for the stabbing, police said. She remained at the home and reported minor injuries. She was taken to a hospital for evaluation, released and later booked into Las Colinas Detention Facility on suspicion of murder.
The couple lived together as common-law spouses and shared a young child, who was at school and not present when the stabbing occurred. Police worked with San Diego Unified School Police to locate the child and confirm the child’s safety.
