A grand jury in Franklin County , Ohio , indicted Matthew Cordle on Monday on charges of aggravated vehicular homicide and operating a vehicle under the influence of alcohol , more than two months after the deadly wrong-way collision . The 22-year-old 's online admission that he was to blame has been watched more than a million times on YouTube . Now , Ohio 's legal system must decide what punishment fits his crime . He is scheduled to be arraigned Tuesday afternoon . If convicted , he faces a maximum sentence of eight and a half years in prison , prosecutor Ron O'Brien said . Polarizing video . `` My name is Matthew Cordle , and on June 22nd , 2013 , I hit and killed Vincent Canzani , '' he says in the video posted last week . In the video , he recounts how he was out with friends , drank heavily and lost control the night of June 22 . Canzani , 61 , died when a wrong-way driver hit his Jeep on Interstate 670 near Columbus , Ohio . The video was posted on a website called `` because I said I would , '' which provides a forum for people to make promises to others . Some viewers were impressed by Cordle 's apparent courage and his plea , `` I 'm begging you , please do n't drink and drive . '' But some viewers thought the video was `` a crock , '' in the words of one commenter on the video site , aimed at reducing Cordle 's probable prison sentence . Remorse called genuine . Canzani 's ex-wife , Cheryl Oates , says she believes Cordle 's remorse is genuine . `` He said I made a huge mistake , and I 'm going to take what 's coming to me , '' Oates said . `` You 've got to respect him for that . '' Oates said Cordle should spend time in prison . But as a mother of two sons , she also feels pain for Cordle when she watches the video . `` It 's gut-wrenching coming from a mother looking at that young boy , and he just does n't understand the damage that he did , '' she said . Lawyer : Leniency is n't goal . Cordle has pledged to plead guilty and said on his video , `` I 'm handing the prosecution everything they need to put me away for a very long time . '' O'Brien said the video has not influenced him to recommend a lighter sentence . `` We had a case against him based on the evidence as I know it before the video was filmed , '' he said . Cordle 's lawyer , George S. Breitmayer III , said leniency was not the goal of Cordle 's video . `` Despite any speculation of his intentions , the video was meant to raise awareness related to the serious issues surrounding drinking and driving , '' the defense lawyer said in a statement sent to CNN . `` In addition , ( Cordle ) hopes his confession will offer the Canzanis some level of closure by avoiding any lengthy , drawn out legal proceedings .
