Do you know who murdered Tsunao? On May 8, 1996, Dr. Tsunao Saitoh, a prominent Alzheimer's researcher at the University of California, San Diego, was tragically murdered along with his 13-year-old daughter, Loullie. The double homicide occurred late at night as the two returned home from Saitoh's laboratory. When they arrived at their house in La Jolla, they were ambushed in their driveway by an unknown assailant. Dr.
Saitoh was shot while still in the car, and Loullie, who attempted to flee, was also gunned down a short distance away.
The investigation revealed .380 caliber shell casings at the scene, identifying the weapon as a Grendel P-12 semi-automatic pistol, although the gun itself was never recovered. Despite a thorough investigation, authorities have struggled to identify a clear motive or suspects. Dr. Saitoh had no known enemies, and neither he nor his daughter were involved in activities that would place them at risk. The case remains unsolved, and law enforcement continues to seek any new leads in the ongoing investigation.
This tragic case left a lasting impact on the scientific community, where Dr. Saitoh was well-respected for his contributions to neuroscience and Alzheimer’s research.
