Empty Crystal Lake Medical Lab Faces Scrutiny Over Insurer Billing and Piles of Unopened Mail

An apparently abandoned medical laboratory in Crystal Lake, Illinois, has drawn scrutiny from law enforcement and federal investigators after accumulating thousands of unopened letters from insurance companies while billing for medical tests patients never received, according to an investigation by CBS News Chicago.

The facility, operating under the business name Niyraa LLC, is located inside a suburban strip mall in Crystal Lake. The operation came to light after an Illinois resident, Katie Duda, discovered an unfamiliar $500 laboratory charge on an Explanation of Benefits statement issued by Blue Cross Blue Shield of Texas. Duda said she had never visited the facility or received services from the provider.

After tracing the charge back to the Crystal Lake address, Duda and her mother visited the storefront and discovered an unlocked, empty office with a sign posted on the entrance instructing delivery couriers to leave mail inside. Inside, no medical personnel, technicians, or office staff were present, and the location appeared entirely vacant.

Subsequent visits by CBS News Chicago over several months revealed thousands of unopened envelopes, predominantly from regional Blue Cross Blue Shield entities, filling U.S. Postal Service bins on the reception desk. Pristine laboratory diagnostic equipment and sealed packages of specimen vials remained in original, unused condition across the premises.

Facility signage and active framed medical laboratory certifications displayed on the walls identify the lab's operator as Mohammed I Quadri. Neighboring commercial tenants, including Brittany Serby, the owner of a nearby wellness clinic, reported that they had never seen Quadri at the location and expressed concern regarding the unlocked doors and unattended mail.

The strip mall's property owner confirmed to reporters that Quadri has maintained consistent rent payments for the commercial space despite not being seen on site for months. Investigative reporters attempted to reach Quadri through phone calls, text messages, emails, and visits to associated addresses, and waited outside the office during standard business hours, but were unable to make contact.

James Scordo, a certified fraud examiner and forensic accountant who reviewed the site, noted that the physical evidence is consistent with a phantom billing scheme. In such arrangements, fraudulent entities bill health insurers for medical services, diagnostic panels, or lab work that were never performed on patients.

Scordo cautioned that fraudulent lab billing can create severe complications for affected individuals. Beyond the potential exposure of personal and private health data, false diagnostic entries can contaminate medical records and negatively affect a person's ability to secure healthcare coverage in the future.

Over the course of several months, the thousands of letters sitting at the front desk were relocated into black and white garbage bags placed in the back of the office. By mid-September, those bags had been removed by unknown individuals, though newly delivered insurance mail subsequently began piling up on the front desk again while the main door remained unlocked.

Local and federal authorities have been notified of the ongoing situation. The U.S. Postal Service Office of Inspector General confirmed it is actively investigating the office, while the Federal Bureau of Investigation stated it had alerted local law enforcement agencies and sanitation crews to prevent the improper disposal of potential evidence. When contacted regarding Niyraa LLC and Quadri, Blue Cross Blue Shield stated that it cannot publicly comment on individual provider relationships.
