LAFAYETTE, La. — A Louisiana prosecutor says a 35-year-old man has been sentenced to 30 years in prison for killing a girl and seriously injuring her mother by driving while drunk.

Ten-year-old Isley Thibodeaux (TIB-uh-doh) and her mother, Misty Thibodeaux, were hit as they left a Carrie Underwood concert in April 2016.

Multiple media outlets report District Attorney Keith Stutes says in a news release that Albert Kirk Sampy pleaded guilty to vehicular homicide — that is, to killing someone by driving while drunk — and negligent injury, and was sentenced Monday. The prosecutor says it is Sampy’s third DWI conviction.

News media report that Judge Patrick Michot (MEE-show) sentenced him to 15 years on the injury charge and the maximum 30 years for vehicular homicide, with the sentences to run simultaneously.
