Tho Ngoc Ly, 40, of San Pablo, California, was last seen on September 6, 2023, when she and her 74-year-old mother, Que Thi Tran, were reported at their shared home on the 1900 block of Sutter Avenue. Her husband, Phuc Vo, reported them missing on September 13, 2023, saying they had left for Southern California in a 2017 Honda Fit after a family argument. Detectives were unable to confirm they reached Southern California and began to find inconsistencies in Vo’s statements.

Investigators later observed Vo driving Ly’s car; the vehicle was recovered in Oakland on December 5, 2023. A search warrant at Vo’s home in February 2024 yielded unspecified evidence, and Vo was arrested. On March 4, 2024, he was charged with two counts of murder with a special circumstance enhancement and held on $2 million bail. A body recovered from the Alameda/Oakland estuary on September 30, 2023, was confirmed by DNA in March 2024 to be Que Thi Tran. Ly’s remains have not been located and the investigation continues. Her two children were placed with other family members after the arrest.
