( CNN ) -- Matt Cordle 's confession does n't beat around the bush : `` I killed a man . '' The Ohio man claims in a video posted on the Internet this week that he killed 61-year-old Vincent Canzani in a drunken-driving crash in June . `` I take full responsibility for everything I 've done to Vincent and his family , '' Cordle says in the video . The 22-year-old has not been charged with any crime , but Franklin County Prosecutor Ron O'Brien said Cordle is a suspect in the deadly crash and a grand jury will be asked to indict him for aggravated vehicular homicide . The video is well-produced and powerful . Cordle 's face is blurred as he begins to tell his story about being out with friend , drinking heavily and losing control the night of June 22 . Attorneys that he consulted with offered to help him avoid any punishment -- `` all I had to do was lie '' -- but he decided to come forward instead . And he wants his video to be a warning to others . `` I ca n't bring Mr. Canzani back , and I ca n't erase what I 've done , but you can still be saved , your victims can still be saved , '' he says on the video . When he gets charged , he will plead guilty , Cordle added . The video was posted on a website called `` because I said I would , '' which provides a forum for people to make promises to others . The founder of the website , Alex Sheen , said Cordle reached out to him via Facebook . `` There are a lot of emotions and parties at play here , so we stay in touch as much as possible , '' Sheen said . `` Matt is doing as well as he can . He 's upset that people are calling his act of confession 'courageous ' rather than focusing on the real issue : drinking and driving kills innocent people . '' Cordle 's current lawyer , George Breitmayer , told CNN affiliate WBNS he did not know beforehand that the video would be released . `` The video he released is a testament to both his integrity and his character , and I know that he intends to fully cooperate throughout the tenancy of all these proceedings , '' Breitmayer said .
