Weihan David Wang was a 20-year-old Chinese-born University of California, Santa Barbara junior studying computer engineering who died on May 23, 2014. Described by family and friends as peaceful, academically focused and devoutly Christian, he had been active in student life and helped code a campus guide called Gaucho Life. He graduated from Fremont Christian School in 2012 and was the only child of Jinshuang Jane Liu and Charlie Wang.

On the evening of May 23, 2014, Wang was fatally stabbed in his Isla Vista apartment. He suffered multiple stab and slash wounds—reports state about 15 stab wounds and some 23 slashes—and was found face-down in a bedroom, partially covered with blankets and clothing. Two other young men in the apartment, Cheng Yuan James Hong and George Chen, were also stabbed and killed that night. Authorities identified 22-year-old Elliot Rodger as the attacker; he died during the subsequent rampage and no arrests were made.

Wang’s parents said he had been planning to move out because of tensions with a roommate and was looking forward to coming home for the summer and celebrating his 21st birthday. Does anyone who knew Weihan or lived in Isla Vista then have memories or information to share that could add detail to his life and final days?
