According to investigators, she was not wearing her seat belt during the accident and was partially ejected from the truck.
According to the nurse's obituary, she is survived by her husband, Joshua Trevillian, her daughter, Kinslee, her parents, two sisters, her best friend, and many nieces and nephews.
Her new husband, family and community are in disbelief over the fatal accident.
"It was really a tragic accident that happened and it's something I think a lot of us are still trying to grasp," said Candice Gentry, a former coworker of Trevillian's.
"Because it's very tragic, when it happened… right after a wedding... it's just terrible."
Gentry revealed that Trevillian became "unbelievably happy" when her boyfriend [Joshua] proposed to her and she spoke about how happy he made her.
"I was so happy for her," she added.
