An American murder suspect attempting to escape to El Salvador was apprehended by U.S. Customs and Border Protection (CBP) officers at Washington Dulles International Airport, officials announced.

Christofer Antonio Argueta Ramirez, 19, of Woodbridge, Virginia, had “purchased a one-way ticket on an El Salvador-bound flight that was departing from Dulles airport around 1:30 a.m.” before being detained on Sunday, according to CBP.

“Officers encountered Argueta Ramirez at the departure gate, verified Argueta Ramirez’s identity, took him into custody, and escorted him back to CBP’s inspection station,” the agency said in a statement. “CBP officers turned Argueta Ramirez over to Metropolitan Washington Airports Authority Police officers.”

Argueta Ramirez is one of two suspects linked to the death of 20-year-old Jose Guerrero, who went missing in Virginia in late 2022, according to Inside NoVa.

Two days after Guerrero disappeared, his family discovered his abandoned car in Woodbridge, which showed signs of a struggle and contained blood, police reported.

Authorities say Guerrero had arranged a drug deal with the two suspects on December 21, but the situation escalated, and Guerrero was “stabbed multiple times,” according to Inside NoVa. His body was later discovered in Prince George’s County, Maryland, in January 2023.

“Customs and Border Protection officers encounter all types of travelers arriving to and departing from the United States, including travelers wanted for allegedly committing seriously heinous offenses,” said Marc E. Calixte, CBP’s Area Port Director for Washington, D.C. “CBP continues to work with our law enforcement partners to help capture dangerous fugitives and to return them to face justice.”
