An illegal Venezuelan migrant accused of executing a Loyola University Chicago freshman from New York entered the US under the Biden administration, and was released under Chicago’s sanctuary city laws before the killing, the Department of Homeland Security said Sunday.

Jose Medina-Medina, 25, allegedly murdered 18-year-old Sheridan Gorman early Thursday morning while she walked along the Chicago lakefront with her friends, according to a DHS release obtained by Fox News.

The illegal alien was caught and released at the border under President Joe Biden’s administration in May 2023, according to the DHS.

Medina-Medina was also previously released from local custody in Chicago— a sanctuary city — just a month later after he was arrested for shoplifting from Macy’s.

The gunman approached Gorman, a freshman from Yorktown, New York, while wearing a mask at around 1:30 a.m., according to cops.

As Gorman attempted to flee, he allegedly shot her in the head, before escaping to a nearby apartment building.

“Sheridan Gorman had her whole life ahead of her before this cold-blooded killer decided to end her life,” DHS Acting Assistant Secretary Lauren Bis said.

“She was failed by open border policies and sanctuary politicians who released this illegal alien twice before he went on to commit this heinous murder,” she added.

“We are calling on Governor Pritzker and Chicago’s sanctuary politicians to commit to not releasing this criminal illegal alien from jail back into American neighborhoods,” Bis said.

Gorman’s grieving parents had earlier issued a tribute describing her as “deeply loving,” and “everyone’s cheerleader.”

No motive has been given for the shooting, which a New York state lawmaker has slammed as evidence of America’s “clearly broken” immigration system.

“Our immigration system is clearly broken and endangering innocent American citizens. No one should be a victim of a system that fails on multiple levels,” State Assemblyman Matt Slater (R-Yorktown) told The Post.

Gorman and friends went out to the pier at Tobey Prinz Beach in the wee hours to try to catch a glimpse of the northern lights, her family said.

That’s when a masked gunman “emerged from the shadows,” according to a police report.

A single bullet casing was found a short distance from Gorman’s body.

“It didn’t seem like it was intentionally targeted toward any of us,” a friend told the Chicago Sun-Times.

“It seemed like he was there for a reason, and we were just [in the] wrong place, wrong time. I’m guessing, because there was not another shot after that. It was just one,” the friend said.

The investigation remains open.
