A man reportedly in the U.S. illegally was charged with killing a missing 19-year-old Maryland woman whose body was discovered off a highway earlier this week.

Hugo Hernandez-Mendez, 35, of Bowie, Maryland, was arrested Thursday in the killing of Dacara Thompson, Prince George’s County Police Department said.

Hernandez-Mendez is an illegal immigrant and had a U.S. Immigration and Customs Enforcement (ICE) detainer issued on Thursday, according to WJLA-TV.

Prince George’s County Police Department told Fox News Digital that the department was not releasing the immigration status of Hernandez-Mendez. ICE did not immediately respond when Fox News Digital reached out.

Hernandez-Mendez was charged with first- and second-degree murder in Thompson’s death.

Maryland Gov. Wes Moore released a statement on the death investigation on Friday, calling Thompson a “bright light” who was “committed to public service.”

“Our entire state mourns the horrible loss of Da’Cara Thompson, who was taken from us by an act of senseless violence,” the governor said in the statement, vowing to use “every tool at our disposal” to hold those responsible for her death accountable.

The 19-year-old’s cause of death has yet to be determined, though police said it may be ruled a homicide based on the evidence collected.

As the investigation remains active, police said detectives are working to determine whether Hernandez-Mendez and Thompson knew each other before the day she went missing.

Hernandez-Mendez is currently being held without bond by the Maryland Department of Corrections.
