An illegal immigrant on the run from US Immigration and Customs Enforcement was busted for a devastating hit-and-run crash that killed a University of South Carolina student Wednesday, according to police and sources.

Rosali I. Fernandez-Cruz, 24, allegedly fled the fatal scene after he failed to yield and rammed his pick-up truck into a motorcycle operated by Nathanial Baker, 21, on Blossom and Assembly Streets near the university’s campus in Columbia around 2 p.m., according to the Columbia Police Department. 

The careless motorist, who was allegedly driving without a license, was wanted by ICE since 2018, a Department of Homeland Security source told The Post. 

“A South Carolina student was killed yesterday because of an illegal alien who had no right to be here,” South Carolina Rep. Nancy Mace said in an X post Thursday.

“We’re going to fight like hell to get every last illegal alien out of South Carolina. We’re praying for the victim, his family, and the students at USC who have been touched by his passing. Hold the Line South Carolina.”

Sources said Fernandez-Cruz, a native of El Salvador, illegally crossed the US-Mexico border at an unknown date but was arrested by border patrol in Hidalgo, Texas on Dec. 24, 2016. He was released the next day and issued a notice to appear as DHS initiated removal proceedings.

An immigration judge in Charlotte, North Carolina, then ordered the undocumented migrant to be sent back to his home country on Sept. 6, 2018, sources said.

South Carolina police said Fernandez-Cruz was driving with two male passengers when he killed Baker, a business major from Glen Allen, Virginia, and fled the crash site. He then abandoned his truck and was nabbed by a nearby officer who found and detained him near the 1100 block of Greene Street, according to cops.

ICE was notified of the arrest after police discovered Fernandez-Cruz’s name listed in the National Crime Information Center database.

The two passengers, who also ran from the scene, aren’t facing criminal charges, police said.

Scores of grief-stricken USC students have since created a memorial on a sidewalk near the deadly crash site, leaving behind messages in chalk, flowers, pictures, and candles, according to local reports.

“Rest in Peace, Nate,” one message said, WACH reported.

“Thank you for the memories. We love you so much.”

Baker’s fraternity, Phi Gamma Delta, also shared their sorrow on Instagram, calling their fallen brother a leader, role model and a true embodiment of what their group stands for.

“Nate Baker brought light, laughter, and love into all of our lives,” the fraternity wrote in the post.

“Nate will always be remembered for the way he showed up for others and the impact he had on everyone around him. His passion, loyalty, and love for this brotherhood will never be forgotten. May we honor his memory by living with the same kindness, selflessness and generosity that he showed to everyone around him.”

The university released a statement calling the situation a tragedy. School officials offered their deepest sympathies to Baker’s family and friends while reminding the campus community that university counselors are available to grieving students.

Fernandez-Cruz was charged with hit-and-run resulting in death, failure to give information and render aid, failure to yield the right of way, and driving without a license.

He is being held without bond at the Alvin S. Glenn Detention Center.
