CHICAGO (AFP) - A young Ohio man who confessed online to killing a man while driving drunk was charged with vehicular homicide on Monday, court records show.

Matthew Cordle, 22, was also charged with driving under the influence.

"When I get charged I will plead guilty and take responsibility for everything I've done to Vincent (Canzani) and his family," Cordle said in the video posted last week on BecauseISaidIWould.com.

Cordle recounted how he "blacked out" behind the wheel after a night of "heavy drinking" then hit another vehicle in a wrong-way crash on an Interstate highway on June 22.

The video ends with Cordle looking into the camera and telling viewers: "I'm begging you. Please don't drink and drive. I can't bring Mr Canzani back ... but you can still be saved. Your victims can still be saved."

Mr Canzani, 61, was described in his obituary as "a gifted photographer" who attended art school in Ohio and later served in the US Navy as a submarine missile technician.

Local news reports at the time of the accident said Mr Canzani died at the scene of the pre-dawn crash, and that medical staff described the driver of the vehicle that hit him as "very, very drunk."

Every day in the United States, almost 30 people are killed in motor vehicle crashes that involve an alcohol-impaired driver, amounting to one death every 48 minutes, according to the Centers for Disease Control.
