Duncan was walking along Gose Pike in Boyle County when she was struck. The Boyle County Circuit Court says Tyler Williams was served warrants last week.
He turned himself in on Friday and paid a $5,000 thousand dollar bond.
Officials say Williams is charged with tampering with evidence, leaving the scene of an accident, and failure to render aid with death or serious injury.
He has an arraignment on November 5th at 9 a.m.
