High School Sweethearts Killed in Hit-and-Run Weeks Before Wedding

A Louisiana State University student and her firefighter fiancé, both just 21 years old, were killed in a suspected drunk-driving hit-and-run near the college campus, cutting short the future the high school sweethearts had spent years planning together.

Leah Victoria Fonte and Shane David Hirstius, both from Metairie, Louisiana, were walking along Nicholson Drive in Baton Rouge early Sunday, October 18, when police say a 20-year-old driver veered off the road and struck them.

The couple had reportedly been celebrating a friend’s birthday before the tragedy.

Fonte, a senior at LSU with dreams of becoming a dentist, died at the scene. Hirstius, a volunteer firefighter known for his dedication to helping others, was rushed to a hospital in critical condition but later died from his injuries.

Police arrested Mia Camille Dawson, 20, in connection with the crash, charging her with vehicular homicide, operating while impaired, reckless driving, hit-and-run driving and vehicular negligent injuring.

The deadly collision occurred around 2:40 a.m. in the 5000 block of Nicholson Drive, near Lee Drive.

According to Baton Rouge police, Dawson was driving a 2016 Nissan Rogue southbound when she allegedly left the roadway and struck the engaged couple as they walked along the right shoulder.

Investigators say Dawson continued driving after the collision and later stopped at a Circle K convenience store on Brightside Drive.

She subsequently notified police that her vehicle had been involved in a crash, according to local reporting.

When questioned about drinking, Dawson allegedly denied consuming alcohol. However, arrest documents obtained by WBRZ indicate that she later submitted to field sobriety testing and a breath test.

Her reported blood alcohol concentration was 0.048%, below Louisiana’s standard legal limit of 0.08% for drivers 21 and older.

But Dawson was only 20, making her subject to the state’s stricter underage drinking-and-driving laws. Louisiana prohibits drivers younger than 21 from operating a vehicle with a blood alcohol concentration of 0.02% or higher.

The test result does not, by itself, establish that alcohol caused the collision, and investigators have not publicly released a final reconstruction of the crash.

Dawson was booked into East Baton Rouge Parish Prison and was scheduled to make her first court appearance Monday afternoon.

The criminal charges remain allegations, and she is presumed innocent unless proven guilty.

Meanwhile, the deaths have left two Louisiana communities mourning a young couple whose lives were closely intertwined.

Fonte and Hirstius had been together since high school and became engaged in 2025. Their wedding was planned for March 2028.

Fonte was completing her senior year at LSU, where she studied biological sciences on a pre-dental track and hoped to pursue a career in dentistry.

Hirstius served as an operator and firefighter with the Third District Volunteer Fire Department in the River Ridge area.

The department described him as a dedicated first responder whose compassion and commitment extended far beyond his official responsibilities.

“Shane was much more than a firefighter,” the department wrote in a tribute, remembering his generous spirit and passion for helping people.

His fellow firefighters said he approached his duties with enthusiasm and was always willing to step forward when someone needed assistance.

The department also mourned Fonte, recognizing the couple’s close relationship and the future they had been preparing to share.

At LSU, school officials confirmed Fonte’s death and announced that counseling and support services would be available to students and faculty affected by the tragedy.

“The LSU family is grieving today after learning of this tragic accident involving our student, Leah Fonte,” LSU Chancellor Jim Dalton said.

LSU President Wade Rousse also expressed condolences to Fonte’s family and friends on behalf of the university system.

The crash has renewed attention to the devastating consequences of impaired driving, particularly among younger motorists.

Under Louisiana law, drivers younger than 21 face stricter alcohol limits, reflecting the increased risks associated with underage drinking and driving.

Vehicular homicide charges can result in substantial prison sentences if prosecutors establish the required elements of the offense, although the outcome depends on the evidence and circumstances of each case.

In Dawson’s case, investigators are continuing to examine what happened before the SUV left the roadway and struck the couple.

Authorities have not announced whether additional charges will be filed.

For the families of Fonte and Hirstius, the investigation comes amid an unimaginable loss.

The two had grown up together, fallen in love and planned to marry, with careers and a future ahead of them.

Instead, their loved ones are now preparing to say goodbye to both of them following a crash that police believe may have involved an underage impaired driver.

As the criminal case moves forward, the couple’s families, friends and fellow students are remembering two young lives lost before their shared future could begin.
