[8] Frazier, who had one sister, was raised by his mother Carol, but he was neglected as a child, and he was also in custody of social services at one point.

Brown begged for her life and Frazier fired a shot in the back of her head and left the apartment briefly to check if anyone had heard it.

[11][12] On March 8, 1992, in Detroit, Michigan, Frazier murdered a young girl in midst of a rape attempt.

Frazier submitted that he fell in love with Detroit homicide detective Monica Childs, who was in charge of the case, and he was thus tricked into confessing to both the murders of Kendrick and Pauline Brown.

[3] In Alabama, Frazier was indicted by a Jefferson County jury in November 1993 on charges of capital murder for the death of Brown.

[20] Two days later, during a sentencing hearing on June 7, 1996, the jury recommended the death penalty by a vote of 10–2 for the charge of capital murder.

[21] On August 8, 1996, for the offence of capital murder, Frazier was sentenced to death by Circuit Court Judge Hon.

[33][34] Frazier and another convicted killer, Tommy Arthur, suggested that their executions should be carried out by either hanging or firing squad, which were not accepted by a federal judge.

[35][36] In 2015, Frazier was one of five death row prisoners who filed a lawsuit opposing the state authorities' bid to administer large doses of midazolam in lethal injection executions.

[42][43] On October 19, 2024, a request for Frazier's death warrant to be issued was made, and on January 7, 2025, Alabama Governor Kay Ivey scheduled Demetrius Frazier's execution date as February 6, 2025, following an order from the Alabama Supreme Court authorizing the Governor to set the date.

[44] Frazier was set to be the fourth person on Alabama's death row to be executed by nitrogen gas inhalation, after Alabama conducted its first three nitrogen gas executions in 2024: Kenneth Eugene Smith in January, Alan Eugene Miller in September and Carey Dale Grayson in November.

Frazier's lawyers argued that the prior three executions showed that the nitrogen gas executions did not guarantee an immediate loss of consciousness before death and a painless death, given that there were witness accounts of the three offenders having experienced conscious suffocation, convulsions and sudden involuntary movements on the gurney.

[48][49][50] U.S. District Judge Emily C. Marks was chaired to hear a federal appeal against the nitrogen gas execution.

They also criticized Frazier for filing such a claim merely weeks before his execution when his transfer took place for more than a decade ago, and described it as a "farfetched argument".

Similarly, the representatives of the Alabama Attorney-General's Office also argued that the appeal should be rejected and called it an attempt by Frazier to stall his upcoming execution.

[61][62] In response to the upcoming execution of his aunt's killer, Pauline Brown's nephew Curtis Starks Jr., who was in high school when the killing occurred, stated that his aunt was an integral part of the close-knit family and her death was a terrible loss, and found it the most devastating thing that Brown was murdered just because she was pleading for her life.

[7] On February 6, 2025, 52-year-old Demetrius Terrence Frazier was put to death by nitrogen hypoxia in the Holman Correctional Facility.

Alabama Corrections Commissioner John Hamm confirmed that Frazier no longer had any heartbeat 13 minutes after the gas was first released.

Frazier also suggested that the media should contact a former detective from Michigan, claiming he made a false confession about the murder of Crystal Kendrick.

Frazier also received a final visit from his mother, sister, and counsel before the death sentence was carried out.

[65][66] After the execution of Frazier, Governor Kay Ivey released a statement, affirming Alabama's stance to enforce the law and pursuit for justice, stating that everyone should abide by the laws of Alabama and expect to face consequences for breaking it without exception, and proclaimed that rapists and killers were not welcome in society.

She added that justice was served with the conclusion of Frazier's case and execution, and offered her condolences to Brown's family.

[7] Similarly, Alabama Attorney-General Steve Marshall condemned Frazier as a monster who killed two innocent people and "left a trail of unspeakable violence", and stated that he was "fairly and appropriately punished" for the crimes he committed in Alabama, and offered condolences to the surviving family members of Brown.
