Another San Francisco man, a man named Bob Tang who also goes by "Bob Tov," has gone missing, however in this case it may be by the man's own volition as police were seeking to question him in connection with the Mother's Day disappearance of Uber driver Piseth Chhay. Tang and Chhay are the same age, 48, and are said to have been friends or acquaintances, and in a release on Wednesday the SFPD's public information officer Grace Gatpandan said, "Mr. Tang is also believed to be the last person who saw Mr. Chhay."

Tang was scheduled to be interviewed by police on Tuesday, May 23, however he left his home on May 22, apparently to respond to a phone call from a security company notifying him of an alarm going off at a property he owns in Antioch. His family has not seen or heard from him since, and they reported him missing on Wednesday, May 24. Investigators now say they've received information that he may have fled the country, possibly to Cambodia.

Chhay's family say he was not working on Sunday, May 14 when he last left home, and he said he was going to meet a friend.

Less than a week later, his Mercedes SUV was found stripped on Davidson Avenue in the Bayview.

Tang, pictured above, is described as an Asian male, 48 years old, approximately 5'4", weighing 130 pounds, with brown eyes and black hair. His vehicle associated is apparently unaccounted for as well, and that is a 2004 Silver Toyota Sienna SUV, with California license plate 5JOT221.

In addition to a search warrant executed at a property in the Bayview on Tuesday, police say they also executed a search warrant in Antioch as well. ABC 7 reports that the Bayview property was Maple Trade Corporation at 1280 Van Dyke Avenue, a property that is associated with Mr. Tang that is about 20 blocks south of where Chhay's car was found.

The SFPD tells ABC 7 that they have reached out to the FBI for assistance if in fact Tang has fled the country.

Anyone who has information about Tang or Chhay's whereabouts is asked to contact San Francisco police via the anonymous tip line at (415) 575-4444, or text a tip to TIP411 with SFPD at the beginning of the message.
