KALAMAZOO, Mich. (AP) — A man who was drunk when his boat struck and killed an 18-year-old swimmer in southwestern Michigan has been sentenced to at least 15 months in prison.

“The decision I made to drive that boat while intoxicated … was the single worse choice I’ve ever made in my life,” Tyler Boyd of Richland said in a Kalamazoo County court Monday.

Jennifer Mitchell said her son was a “perfect child.”

Boyd will be eligible for parole after 15 months in prison.
