An illegal immigrant has been charged with killing four people after allegedly driving while intoxicated the wrong way on a highway and striking another vehicle, Oklahoma authorities said Tuesday.

Michael Rosario-Cruz, 27, was released from a hospital and booked into the Canadian County Jail on multiple charges, including four counts of second-degree murder, two counts of DUI causing great bodily injury, transporting an open container, firearm possession, carrying firearms while under the influence, and driving the wrong way on a one-way road.

According to the Oklahoma Highway Patrol, Rosario-Cruz was driving westbound in the eastbound lanes of Interstate 40 in Canadian County early Friday morning when he collided head-on with another vehicle. The struck vehicle caught fire, and all four occupants were killed.

The victims, who ranged in age from 18 to 20, were identified as Kiercey Hickson, 20, Quincy Jones, 19, Haliegh Salazar, 18, and Brad Palmer, 18.

“Driving impaired is a reckless, life-changing decision,” the Highway Patrol said in a social media post announcing the charges. “The loss of these young lives will have a lasting impact on countless family members, friends, and communities.”

A spokesperson for the Oklahoma Highway Patrol told Fox News Digital that Rosario-Cruz is the subject of a U.S. Immigration and Customs Enforcement (ICE) detainer request. This means ICE has asked to be notified prior to his release from custody so they can take him into custody and begin deportation proceedings.

It is not clear when Rosario-Cruz entered the United States or what his country of origin is. Fox News Digital has reached out to ICE and the Department of Homeland Security (DHS) for comment.

The four victims were recently honored at a vigil at El Reno High School, where three of them had recently graduated. Nancy Salsman, a retired teacher, said three of the victims were once students in her second-grade class.

“You just make that connection that never goes away,” she said. “They’re always your kids. And when something like this happens, we come together.”
