Baltimore County paramedic Christopher Carroll arrested on 23 charges after alleged contamination incidents at fire stations

Arrest follows months-long investigation into alleged on-duty misconduct

Baltimore County police have arrested a Baltimore County Fire Department employee after a criminal investigation into allegations that bodily fluids were placed on or in workplace items at county fire facilities.

Christopher Carroll, 36, is charged with 23 offenses. Court records list charges that include knowingly and willfully causing another person to ingest bodily fluids. Police said Carroll turned himself in on Wednesday after authorities obtained a warrant for his arrest. He is being held without bond in Baltimore County, police said.

What investigators allege occurred inside county facilities

The case stems from complaints that sexually explicit material was recorded in spaces identifiable as county fire stations and that acts shown in the material involved workplace property. Reports under review by investigators describe alleged contamination of shared equipment and coworkers’ personal items and food.

Earlier departmental communications to personnel described a safety response that included sanitizing measures across facilities and vehicles. The department also encouraged employees who were concerned about exposure to seek medical guidance through available occupational health channels.

Workplace response included hazmat-style cleaning and equipment review

In the weeks after the allegations surfaced, county fire leadership initiated department-wide cleaning measures that extended beyond the initially affected location. The actions included cleaning of common areas and equipment, as well as additional attention to high-contact and shared-use surfaces and appliances typically found in station living quarters.

County officials have also reviewed potential costs associated with deep-cleaning and replacing certain items used across stations, reflecting the practical challenges of restoring confidence in shared equipment and food-preparation areas when contamination is alleged.

Health and legal context: allegations, charges, and next steps

Public health concerns in cases involving bodily fluids often center on two issues: the plausibility of disease transmission and the need for employees to have clear guidance about testing and occupational exposure protocols. In this case, officials have communicated that medical risk assessments were part of the internal response while the criminal investigation proceeded.

The criminal case now moves through Maryland’s court process. The charges filed do not establish guilt; Carroll is presumed innocent unless and until proven guilty in court. Future court hearings are expected to address the basis for detention, the evidentiary record supporting the charges, and any conditions that could apply if release is requested.

If you or someone you know works in a shared workplace environment and believes contamination or exposure may have occurred, occupational health guidance typically recommends documenting concerns promptly, preserving potential evidence where appropriate, and seeking employer-provided medical evaluation resources.
