A California man who reported his wife and her mother missing in September has been charged with their deaths, police said Monday. 

Phuc Vo, 40, is charged with two counts of murder in the slayings of his wife, Tho Ly, 40, and her 74-year-old mother, Que Tran, the San Pablo Police Department said. 

Authorities have not located the bodies of the women and have not disclosed how they were killed. 

Vo filed a missing persons report on Sept. 13, 2023, saying that both women had gone missing a week earlier. He said they left their home in a 2017 Honda Fit to travel to Southern California following a family argument, police said. 

“Subsequently, Vo was identified as a person of interest in connection with the missing persons case,” a police statement said. 

On Feb. 29, investigators searched Vo’s home, and he was arrested. Neighbors told Fox San Francisco that authorities were seen digging up the yard at Vo’s home.

He is being held with no bail at the Martinez Detention Facility, according to jail records.
