Disgraced ex-Illinois Gov. Rod Blagojevich shared a stunning theory about the illegal migrant accused of executing a Chicago area college student in cold blood — that it was part of some “gang initiation.”

Blagojevich, a Democrat whose 14-year prison sentence for federal corruption charges was cut short after President Trump commuted his sentence in 2020, wrote on X that he believes Jose Medina-Medina murdered Sheridan Gorman in an effort to make an impression with a local gang.

“Sheridan Gorman’s killer is being held in isolation. I suspect Pritzker & the Dems are hiding him to COVER-UP the fact that this illegal immigrant killed an innocent young girl as part of a GANG INITIATION,” he wrote.

“I know gangbangers & how they operate. I lived with them for 8 years. And I know Pritzker & the Dems. Bet you I’m right,” the self-described “Trump-o-crat,” who served in the state’s top office from 2003-2009, said.

Gorman, 18, was a freshman at Loyola University — and from Westchester County — when she was allegedly shot by Medina-Medina, a 25-year-old Venezuelan national, on the Loyola Beach Pier at around 1:30 a.m. Thursday.

She and her friends were near their campus and taking a walk to try to catch a glimpse of the Northern Lights when Medina-Medina allegedly jumped out at them wearing black clothes and a black mask and wielding a gun, the Chicago Tribune reported.

When they fled, he allegedly fired off a single shot that struck Gorman in the head — and killed her.

Medina-Medina was allegedly caught on camera firing the gun, with his own mother helping ID him after investigators shared footage of the heinous shooting.

In May 2023, he was apprehended by the US Border Patrol and released during the Biden administration, according to the Department of Homeland Security.

He was sprung free again in June 2023 after a shoplifting arrest in Chicago.

Since Medina-Medina’s arrest, The Illinois Venezuelan Alliance said that there has been an uptick in hateful comments directed at the local Venezuelan community — while also raising questions about whether the killing could be gang-related, Fox32 Chicago reported.

“Most Venezuelans in the United States and in Chicago are hard-working people. This is a bad apple in the group,” Interim Executive Director Luciano Pedota told the outlet.

Chicago police told the outlet they could not confirm the motive.

Medina-Medina was charged with first-degree murder, attempted murder and weapons charges and is slated to appear in court on Friday.

He failed to show up for a detention hearing on Monday after being hospitalized for Tuberculosis, the Tribune reported.
