Authorities Wednesday released the name of a woman who was fatally stabbed this week at her Lakeside home, allegedly by her adult son.

Deputies responding to an emergency call early Monday afternoon found Judith Anderson, 79, mortally wounded at the residence in the 9400 block of Riverview Drive, according to the San Diego County Sheriff’s Department.

Paramedics pronounced her dead at the scene.

While investigating the suspicious death, deputies detained the victim’s son, 50-year-old Arleigh Clifford Anderson. Detectives interviewed him, then arrested him on suspicion of murdering his mother, Lt. Joel Stranger said.

“The motive is still under investigation,” the lieutenant said.
