A 23-year-old San Francisco woman was arrested this week after detectives located a missing, at-risk 17-year-old at a South San Francisco hotel, according to police. Authorities identified the suspect as Liliana Mejia, who faces charges that include human trafficking of a minor, as well as pimping and pandering. The teen, described by police as an at-risk runaway from the East Coast, was taken into protective custody while detectives continued the investigation.
According to KRON4, South San Francisco detectives went undercover after responding to an online posting that depicted the victim and advertised commercial sex services. Investigators say that ad led them to a hotel on the 1300 block of Veterans Boulevard, where they found the minor and arrested Mejia.
Undercover Response And Regional Context
The decision to answer online ads and make undercover contacts is part of a broader, coordinated effort by law enforcement to identify trafficking victims and pursue those accused of exploiting them. As outlined by the California Department of Justice, recent multi-agency operations such as Operation Coast to Coast have mobilized dozens of agencies and offered services to survivors who are located during these stings.
What The Charges Mean
Under California law, causing, inducing or persuading a minor to engage in commercial sex is prosecuted as human trafficking (Penal Code §236.1), a felony with significant prison exposure; see Penal Code §236.1. Pimping and pandering (Penal Code §266h and §266i) are also felony offenses with multi-year penalties when victims are minors, with the statutes and typical penalties detailed on state code and legal reference pages.
The South San Francisco Police Department said the case remains an active investigation and asked anyone with information to contact criminal investigators at (650) 877-8900 or submit tips via the department’s press office.
