DHS moves to deport alleged killer and Tren de Aragua member after Biden admin let him into the US

The Department of Homeland Security is moving to deport an accused killer and Tren de Aragua gangbanger who was let into the US under the Biden administration, The Post has learned.

The feds lodged a detainer on Thursday, requesting Colorado authorities hand over Michel Jordan Castellano Fonseca so they can send him back to Venezuela.

Castellano Fonseca was arrested after he allegedly broke into an apartment in Aurora, Colorado, on Sunday and shot his wife and sister-in-law — while five terrified children cowered in the corner watching, Homeland Security sources told The Post.

The Venezuelan migrant’s sister-in-law was killed in the heinous attack.

Aurora cops nabbed Castellano Fonseca on Monday and charged him with homicide.

The DHS has now lodged a detainer request so they can take him into custody for deportation once he is no longer in the custody of local authorities, agency officials said.

However, Aurora cops may not play ball due to sanctuary laws.

“Aurora, Colorado — a sanctuary city — has given cover to Tren de Aragua gang members to terrorize our communities,” Assistant Homeland Security Secretary Tricia McLaughlin told The Post.

“The brave men and women of ICE will be relentless in their efforts to ensure Tren de Aragua terrorists are removed from our country for good,” she added.

The Venezuelan migrant crossed the border illegally in December 2023 and was swiftly released into the US with a notice to appear before an immigration judge at a future date, according to DHS.

Nearly a year after he jumped the border, Castellano Fonseca was collared for driving without a valid license in Port Richey, Florida.

During his latest arrest, authorities also discovered that the illegal migrant had a warrant stemming from domestic violence charges in Arapahoe County, Colorado, DHS said.

Aurora descended into a Tren de Aragua gangland last year after dozens of illegal Venezuelan migrants flocked to the quiet Denver suburb.

The gangbangers soon began taking over various dilapidated apartment complexes, terrorizing residents there with gun crime, theft and drug dealing.

In one viral video, gun-toting Tren de Aragua gangbangers were seen trying to kick in doors at one of the notorious apartment buildings before a man was fatally shot outside minutes later.

President Trump has prioritized targeting Tren de Aragua gang members across the US and designated the group as a foreign terrorist organization upon returning to the White House.
