On the night of May 8, 1996, Dr. Tsunao Saitoh and his 13-year-old daughter Loullie were ambushed in their La Jolla driveway after returning from Dr. Saitoh’s laboratory. Dr. Saitoh was shot while still in the car; Loullie ran but was shot a short distance away. Investigators recovered .380 caliber shell casings linked to a Grendel P-12 semi-automatic pistol, but the firearm was never found.

Saitoh had no known enemies and neither victim was involved in activities that would put them at risk. The double homicide remains unsolved and continues to draw attention because of Dr. Saitoh’s prominence in Alzheimer’s research.

Did anyone in the La Jolla area at the time notice a suspicious vehicle or person near the Saitoh home that night?
