ST. JOHNS COUNTY, Fla.: A 37-year-old woman was killed on I-95 north of State Road 16 late Monday night.

According to the Florida Highway Patrol, Brienne Lemay was traveling northbound on a motorcycle in the left lane of the interstate when the motorcycle traveled into the path of a semi-truck in the center lane.

Troopers said Lemay was pronounced dead at the scene.

Lemay’s eldest brother, Brian Chandler, said his sister is a beloved veterinary surgeon and pilot with a clean driving record. “I just, I lost it,” Chandler said. “You never want to find out that way and that’s the part that’s been frustrating.”

“My sister was so incredibly passionate about animals and helping them,” Chandler said. “She’s made a tremendous impact on some people’s lives and saving their loved ones — pets are a really important part of people’s family and somebody who dedicates their life to healing and helping and saving — that should speak volumes for who she is as a person and the type of heart that my sister had.”

Chandler noted that the trooper he spoke with was “very respectful.”
