Lauren Akerson was a passenger in a vehicle that was hit last November. Officers said Otis Newcomb of York was drunk. Court records indicate his blood alcohol level was .113, well over the legal limit.
On Tuesday in York County District Court, Newcomb agreed to plead no contest to felony manslaughter.
The victim's family approves of the agreement, saying they didn't want to endure what could be a painful trial for them.
Newcomb will be sentenced in August, and could get up to 20 years in prison.
Authorities say the van Newcomb was driving on Nov. 2 crossed the center line on U.S. Highway 34 about two miles west of York, striking another vehicle carrying 31-year-old Lauren Akerson.
The second-grade teacher from Aurora died as a result of the injuries she sustained in the crash.
