Fairfax County repeatedly refused deportation “detainer” requests from Homeland Security and released an illegal immigrant from Venezuela back into the community despite arrests for driving under the influence, hit-and-run, firearms crimes and malicious wounding, Homeland Security said Thursday.

Yohandri Roger Mosquera-Rosas was first arrested when he snuck into the county in October 2022 and was released under Homeland Security Secretary Alejandro Mayorkas’s “parole” powers.

He quickly amassed a massive rap sheet with arrests in Fairfax County starting on New Year’s Day in 2023, where he was charged with malicious wounding, child endangerment and multiple gun-related charges. In June 2023, he was charged with another firearm crime, then earlier this year was twice charged with DUI and hit-and-run.

In three of those instances, U.S. Immigration and Customs Enforcement issued a “detainer” request asking the county to cooperate in turning Mr. Mosquera over for possible deportation, but the county refused. In the fourth instance, Mr. Mosquera was released before ICE could lodge a detainer.

“Yohandri Roger Mosquera-Rosas’ charges render him a significant threat to the residents of our Northern Virginia neighborhoods,” said Liana Castano, field director for ICE’s Washington office.

She labeled Mosquera an “egregious” offender.

ICE officers tracked down Mr. Mosquera in Springfield on Sept. 12. He is currently being held at an ICE facility in Farmville, Virginia.

Fairfax County operates largely as a sanctuary jurisdiction, refusing cooperation with ICE.

The sheriff’s office, which runs the jail, said it requires a warrant signed by a judge in order to cooperate. ICE says that since immigration enforcement is a matter of civil law, no such warrant is possible.

The sheriff’s office also says that when it did cooperate on holding people for ICE, the federal agency would sometimes fail to show and pick them up.

The Washington Times has reached out to the office for this story.

Mr. Mosquera is the latest in a string of cases where ICE says Fairfax County has refused to cooperate.

Many of those cases involve sex crimes committed against young teen girls.

That includes Jose Fabricio Veizaga-Vargas, a Bolivian man convicted in July of misdemeanor sexual assault of a child.

ICE says Fairfax County declined to honor a detainer request, releasing the convict back into the community.

In August, Veizaga was arrested for drunken driving a blood alcohol level of 0.15 to 0.2. The county again defied a detainer, ICE said. A week later, he was arrested on child pornography charges and again the county authorities refused ICE’s detainer request, the agency said.

ICE nabbed Veizaga in Annandale on Aug. 19.
