Timothy Denton also was sentenced on Wednesday to six to eight years in prison for a burglary in a separate case. The sentences will be served at the same time.
Authorities say Denton got into an argument with Cody Williams in April 2012. Police say Denton ran after Williams and threw a 10-inch wrench at him. It struck Williams’ head, fracturing his skull.
Williams has since recovered but suffers migraines and emotion stress from the assault.
