Businessman sentenced for traveling to pay for sex following HSI, local partner investigation
SAN ANTONIO — A San Antonio man was sentenced Nov. 8 to more than three years in prison for interstate travel in furtherance of racketeering activity following a human trafficking investigation led by Homeland Security Investigations (HSI) with assistance from the San Antonio Police Department and the Texas Attorney General’s office.
Derek Wai Hung Tam Sing, 52, was sentenced by a federal judge Nov. 8 to 46 months in federal prison followed by three years of supervised release. Sing pleaded guilty July 18.
According to court documents, on June 11, 2021, HSI received a request for assistance regarding an ongoing state human trafficking investigation. Texas law enforcement officers were investigating a massage parlor that was being used to engage in sex trafficking and money laundering. On April 4, 2022, HSI and the San Antonio Police Department arrested Sing without incident.
In court, Sing admitted to traveling from San Antonio to California once a month to check on his business, where he hired women to engage in sex for money. During the investigation, officials rescued three adult women from the sex trafficking case.
Assistant U.S. Attorney for the Western District of Texas Tracey Thompson prosecuted the case.
