Britnee Angelique Miller was born on June 2, 1993, and spent her childhood and teenage years in Escambia County, Florida. She was the daughter of Tina Lasonya Brown and grew up in the close quarters of a trailer park in Ensley. Accounts of her upbringing point to a troubled and unstable environment marked by strained family relationships and an absence of positive adult influences.

Neighbors described Britnee as a quiet but sometimes volatile teenager who seemed heavily influenced by her mother’s strong personality. The two lived together in a small trailer home, and Britnee’s social world revolved around a tight circle of local acquaintances and family. She became friends—and eventually rivals—with 19-year-old Audreanna Zimmerman, who also lived in the same mobile home park.

Tensions escalated dramatically in early 2010 after Miller discovered that Zimmerman had been involved with her boyfriend. A confrontation between the two erupted into violence when Miller tried to physically assault Zimmerman, and Zimmerman defended herself by using a stun gun. The incident left Miller humiliated, fueling deep resentment that would soon spiral into lethal revenge.

As a 16-year-old high school dropout at the time of the crime, Miller was legally a minor. Despite her age, she was quickly swept into her mother’s plan to punish Zimmerman. Later court proceedings revealed that Miller had experienced childhood trauma, abandonment by her father, and sexual exploitation—factors that would become central arguments in her legal defense.

On March 24, 2010, Britnee Miller became a direct participant in one of the most vicious murders in Escambia County’s recent history. That day, under the pretense of reconciliation, her mother, Tina Brown, invited Audreanna Zimmerman over to their trailer. Once Zimmerman stepped inside, she was ambushed. Miller joined her mother and their neighbor, Heather Lee, in beating Zimmerman.

Brown led the attack with a crowbar, striking Zimmerman repeatedly, while Miller and Lee restrained her and participated in the assault. Brown also used a stun gun to shock the victim several times. After Zimmerman was subdued, Miller helped drag her into Brown’s vehicle. The group drove her to a wooded area nearby, a secluded spot chosen to hide the crime.

Once there, the women forced Zimmerman out of the car. Brown doused her with gasoline while Miller and Lee stood by. Brown then set Zimmerman on fire, leaving her to die.

Despite the catastrophic burns covering most of her body, Zimmerman was able to crawl to a nearby house to call 911. She managed to tell responding deputies exactly who her attackers were. She was airlifted to a burn center in Mobile, Alabama, but died 16 days later on April 9, 2010.

Miller was arrested the same day as her mother and charged with first-degree premeditated murder and kidnapping. Because she was 16 years old at the time of the crime, Florida law exempted her from the death penalty.

Facing overwhelming evidence and her mother’s co-defendant testimony, Miller entered a guilty plea to first-degree murder. On May 7, 2013, she was sentenced to life in prison without the possibility of parole.

In March 2017, Miller sought to withdraw her guilty plea, arguing she had not understood that she could receive a life sentence even after cooperating. Her attorneys also noted the evolving legal consensus that juveniles should not automatically be condemned to die in prison. However, the courts rejected her motion.

In October 2017, Miller was re-sentenced under newer legal guidelines requiring juvenile lifers to have the opportunity for sentencing reviews. During the proceedings, her defense presented evidence of severe trauma and abuse throughout her childhood, arguing that her participation stemmed from her desperation for her mother’s approval. Despite these mitigating factors, Circuit Judge Gary Bergosh again imposed life imprisonment on November 6, 2017, but granted Miller the right to a sentence review after 15 years.

On April 3, 2019, the Florida First District Court of Appeal upheld her sentence. As of 2025, Britnee Miller remains incarcerated at the Lowell Correctional Institution, where she will be eligible for her first sentence review hearing in 2032.
