This morning, an Ohio grand jury indicted Matthew Cordle—the drunk driver who released a YouTube video last week confessing that he'd killed 61-year-old Vincent Canzani—on charges of aggravated vehicular homicide.

The Columbus Dispatch reports that the 22-year-old surrendered this afternoon at the Franklin County Jail and intends to plead guilty at an arraignment tomorrow:

George Breitmayer III, Cordle’s Columbus lawyer, said his client will plead guilty to the charge, potentially accepting an eight and one-half year prison sentence, in fulfilling the “ sincere” promise made in his video.

“Any of the naysayers out there, they are going to find out ... he didn’t do this (video) for any other purpose but to raise awareness about drunken driving and get some closure for the victim’s family,” Breitmayer said this morning.

The grand jury also indicted Cordle on a charge of operating a motor vehicle while intoxicated.
