Olivia Nicole Deffner, a 24-year-old woman from Plano, Texas, tragically lost her life on September 10, 2017. Olivia, who was born on October 2, 1992, in Charleston, South Carolina, had a vibrant and accomplished life. She graduated Summa Cum Laude from Ronald Reagan High School in 2011 and later earned a B.S. in Marketing from UT Dallas in 2015. Olivia was known for her passion for travel, her love for animals, and her successful career as a Digital Marketing Manager with Texas Instruments in Dallas.
On the evening of September 10, 2017, Olivia was attending a Dallas Cowboys viewing party hosted by Meredith Hight, a 27-year-old woman, at her home in Plano. The gathering turned into a horrific mass shooting when Meredith's estranged husband, Spencer Hight, stormed the home and opened fire. Spencer Hight, 32, was reportedly struggling to move on from his deteriorating marriage with Meredith, who had filed for divorce in July of that year.
The shooting resulted in the deaths of Meredith Hight and seven of her friends, including Olivia Nicole Deffner.
The Plano Police Department identified Spencer Hight as the gunman responsible for the massacre. He was heavily armed and was shot and killed by a responding police officer at the scene. The incident is considered the worst mass shooting in Plano's history. The investigation revealed that Spencer Hight's marriage to Meredith was marked by alcoholism and violence, and his inability to cope with the separation led to the tragic event.
The victims of the shooting, including Olivia Nicole Deffner, were remembered for their vibrant lives and the impact they had on their communities. Olivia's family and friends mourned her loss deeply, celebrating her achievements and the joy she brought to those around her. The Plano community was left in shock and grief, grappling with the senseless violence that claimed the lives of eight individuals.
