A suspected killer who's drawn comparisons to the fictional serial killer “Dexter” is still at large and “America’s Most Wanted” is hoping the public can help them track him down.

Bob Tang allegedly became irate on Mother’s Day 2017 when his wife announced that she wanted a divorce. But was it a simple breakup or a deeper betrayal? Tang believed his wife had been having an affair with his best friend, Piseth Chhay, “America’s Most Wanted” noted in Monday’s episode. Chhay was also married and his cousin, SoSo, Chi told San Francisco outlet KGO-TV in 2017 that the two wives were "besties." (Chi also denied the rumors of an affair.) 

Tang allegedly killed Chhay, a San Francisco-based Uber driver, following the apparent revelation and dismembered his body, according to the FBI. Chhay's remains were found more than a month later in the Hayward warehouse that Tang operated.

Renowned cold-case investigator Paul Holes, who famously helped track down the Golden State Killer, noted in Monday’s episode that the “crime scene cleanup” at the warehouse was “poorly done.”

“This is showing an unsophisticated offender that was likely in a rush,” Holes said.

Tang was also apparently in a rush to flee the country. His car was found three weeks after the murder abandoned at San Francisco International Airport with his cell phone left inside. Investigators discovered he had booked a one-way ticket to Cambodia, where he had dual citizenship.

“America's Most Wanted Overtime,” which follows the franchise's main episodes and takes deep dives into the cases featured, compared the dismembering techniques to Dexter Morgan from the show “Dexter.” The fictional protagonist is a blood splatter expert who murders serial killers on a regular basis. Investigator Joscott Morgan noted on the show that Tang had allegedly “acquired power tools” and packaged Chhay's remains. The fictional killer also had a habit of using power tools to discard his victims.

Investigators think that Tang is likely in Cambodia.
