Dat Tat Tran was a 36-year-old University of California, San Diego student who disappeared on March 29, 1997. He told his landlady he planned a trip up north for spring break and rented a car in San Diego. On March 31 he rented a second vehicle from a Washington state agency; that car was never returned and the rental company later reported it stolen.

On July 22, 1997 the Washington-rented vehicle was found abandoned in a hotel parking lot and had reportedly sat there for three to four months. Tran has had no contact with family or friends since his disappearance and his whereabouts remain unknown. The San Diego Police Department lists the case as an unsolved missing person investigation.

If anyone knew Dat Tran, his travel plans, or recognized the Washington rental vehicle’s location, can you share what you know?
