A 30-year-old Chicago city employee was arrested Tuesday and charged with multiple felonies after authorities accused him of sexually abusing a 14-year-old girl he met through a dating app, according to the Chicago Sun-Times, which cited police and court records.
Oswaldo Lorenzana De La Rosa is a civilian timekeeper for the city's Office of Public Safety Administration, not a sworn police officer. The Sun-Times reported that police allege the girl knew him by another name after meeting him on a teen dating app and that the alleged sexual encounters occurred at his Belmont Cragin home.
The police account described by the Sun-Times alleges that Lorenzana De La Rosa picked the girl up from school and provided gifts and other items. Those details remain allegations; the charges are not findings of guilt, and the available account does not establish whether the girl was contacted through any city-related system or whether his employment played a role in the alleged conduct.
What the charges allege
Lorenzana De La Rosa faces charges of felony criminal sexual assault, aggravated criminal sexual abuse, traveling to meet a minor, grooming and indecent solicitation of a child, the Sun-Times reported. The charges reflect prosecutors' allegations based on police and court records; the case remains pending.
He was expected to appear Thursday at the Leighton Criminal Courthouse for a detention hearing. Under Illinois' Pretrial Fairness Act, cash bail was eliminated and replaced with detention hearings. For eligible serious offenses, prosecutors must establish by clear and convincing evidence that detention is necessary to protect against a real and present threat, according to the Illinois State Bar Association.
The city job is administrative
OPSA was proposed under then-Mayor Lori Lightfoot in 2019 to consolidate human-resources, payroll and information-technology functions serving the Chicago Police Department, Chicago Fire Department and Office of Emergency Management and Communications, according to the City of Chicago. The department's creation was also tied to a broader effort to shift administrative work away from sworn personnel, as described in a Chicago Police Department workforce study.
City records cited by the Sun-Times list Lorenzana De La Rosa's annual salary at $61,548. OPSA was budgeted $152.1 million for fiscal year 2025 to handle administrative, technical and payroll operations across the city's public-safety departments, according to The Daily Line.
It remains unclear from the available records whether OPSA has suspended or discharged Lorenzana De La Rosa, or whether the agency has opened a separate personnel investigation. An arrest or criminal charge is not itself proof of misconduct or guilt.
Online-enticement reports measure allegations, not convictions
The allegations fit a broader law-enforcement concern about adults using online services to contact children, but national reporting data cannot establish a connection to this case or show how often similar conduct leads to prosecution. The National Center for Missing & Exploited Children said its CyberTipline received 1.4 million reports concerning online enticement in 2025, including more than 800 reports in which an offender traveled to meet a child. NCMEC describes these as reports of suspected exploitation, not convictions.
NCMEC also reported that CyberTipline reports related to child sex trafficking rose 323% from 2024 to 2025, while cautioning that the 2024 REPORT Act changed reporting requirements. That qualification makes the figure a measure of reports received—not a direct measure of the number of offenses or successful prosecutions.
A separate Illinois example
In a separate 2020 investigation in Marion, Illinois, investigators arrested a 19-year-old man accused of exploiting and blackmailing multiple juvenile victims in Illinois, California and South Dakota, according to the Illinois Attorney General's Office. That case involved different alleged conduct and multiple victims, so it is an example of online child-exploitation investigations rather than evidence of a common pattern with the Chicago prosecution.
The Chicago case will turn on evidence presented in court, including the allegations attributed to police and the charges filed by prosecutors. The next immediate procedural step is the detention hearing; the available information does not establish its outcome.
