A Louisiana State University student and her firefighter fiancé, high school sweethearts, were killed when a woman allegedly struck them with her vehicle as they walked along the side of a road early Sunday morning.

The Baton Rouge Police Department identified the victims as 21-year-old Leah Fonte and 21-year-old Shane Hirstius, who were engaged. Officers arrested Mia Dawson, 20, in relation to the incident on charges of operating while impaired, reckless operation of a vehicle, hit-and-run driving, vehicular homicide and vehicular negligent injury.

Officials said Dawson veered off the road at around 2:40 a.m. Sunday and struck the two people who were walking on the right shoulder of the road.

Fonte died at the scene, while Hirstius was taken to a hospital, where he later died.

In a Facebook post, the River Ridge Volunteer Fire Department said: "Shane was much more than a firefighter. He was a person with an enormous heart, an unforgettable smile, and a genuine passion for helping others."
