A grim discovery was made over the weekend in Hayward casting greater suspicion on a man named Bob Tang, the person of interest in the May disappearance of 48-year-old Uber driver and married father of two, Piseth Chhay. As KRON 4 reports, SFPD investigators were called to a warehouse in Hayward Saturday morning where they found bags of mutilated human remains, and this warehouse is connected to Tang, who is believed to have fled the country before he could be questioned by police last month.

Chhay was last seen on May 14, Mother's Day, and his wife says he was headed to see Tang that afternoon. Chhay was a full-time driver for Uber but was not on duty that day. His vehicle, a Mercedes SUV, was found stripped less than a week later on a desolate street in the Bayview, and police began to focus on Tang, 48, who owned a business in a warehouse about 20 blocks from where the car was found. Police further conducted a search warrant at an address in Antioch owned by Tang, and he was last seen by his family on May 22, allegedly heading to that property to check on a security alarm that had gone off. Tang was scheduled to meet with SFPD investigators on May 23, but his family reported him missing on May 24. His car was found just about a day later in an SFO parking garage, and it is believed that he fled to his native Cambodia. The FBI is now involved in trying to track him down.

SFPD spokesperson Robert Rueca said in a release on Sunday that the department had been alerted to the possible remains — apparently located by the smell, according to NBC Bay Area — by workers at the warehouse, which is "the size of a retail warehouse store." The Medical Examiner's Office then took custody of the remains, and because of their condition "investigators will need to use DNA testing to identify the deceased."

KTVU reports that the warehouse is the US Trading company at 21118 Cabot Road in Hayward, and that Tang used to work there.

Chhay's wife gave a tearful interview Sunday to ABC 7, saying of Tang, "We believe he's in Cambodia," and adding, "I just hope that body part doesn't belong to my husband, but if it is, Bob Tang had something to do with it."

Kim also said that Chhay's mother and aunt had arrived in town and would be providing DNA samples to aid in the investigation.
