A former Birmingham police detective will spend the rest of her life in prison without the possibility of parole.

Alfreda Fluker, 42, was convicted of capital murder in November in the “love triangle” shooting death of 43-year-old Kanisha Nicole Fuller, and attempted murder of Mario Theodore White, who was Fluker’s police partner and common-law husband.

The shooting happened in Birmingham’s Germania Park in 2020.

Since it was a not a death penalty case, Fluker’s only possible sentence was life without parole. Her sentence was handed down Monday morning.

“No one is above the law,’’ District Attorney Danny Carr said. “We hope that this sentence today finally gives the victim’s family some peace.”

Prosecutors in the four-day trial said Fluker was “intentional, cold, calculated and exact” when she found Fuller and White together in White’s city vehicle in the Birmingham park that Friday night and emptied her service weapon on the SUV.

Defense attorneys, however, said Fluker was overcome with anger when she found Fuller and White having sex in the SUV and fired in the heat of passion, not intending to hurt or kill anyone.

The 43-year-old Fuller, the mother of teen son, died a short time later at UAB Hospital. White was not injured and later resigned from the department.

Police at the time labeled the deadly shooting the result of a “love triangle.”

Fluker and White were partners on the Birmingham Police Department’s Crime Reduction Team. They also had been involved romantically for several years and had lived together since 2016.

Fluker has remained in the Jefferson County Jail without bond since her April 11, 2020, arrest. She was immediately fired from the police force.

Fluker testified during her trial, chronicling the events of that night.

She said she and White had gotten into argument when he prepared to the leave the home about 10 p.m. He took a shower, a Viagra pill and put on cologne.

Fluker said their argument turned physical and then White left their Birmingham home. She began to track him on a phone app, and eventually went to Germania Park where she said she found White and Fuller having sex.

White testified that they were only talking.

“They were having sex in the passenger’s seat in the work truck,’’ Fluker said Wednesday when she took the witness stand in her own defense. “She was on top of him, and they were having sex.”

“All I could visualize was them having sex in that truck that I ride in every day,’’ Fluker said.

She said she and White got into another physical altercation. At that point, she went to her own vehicle to retrieve her gun, and White and Fuller “hauled butt” out of the bar.

Fluker said she then began firing her gun, which she claimed was from about 100 to 150 feet away.

“I went to my truck, and I pulled my weapon and I just started recklessly firing,’’ Fluker said.

She said she wasn’t trying to kill anyone. “I wanted Mario to know to stop playing with me. I wanted him to respect me,’’ she said.

Fluker said White left the park but then put his truck in reverse and re-entered. They got into another argument, all while a wounded Fuller remained in the passenger’s seat.

Fluker said she told White they needed to get Fuller to the hospital. “He’s like, ‘No, I can’t leave her truck in the park,’’’ she said.

Fluker said she then told White she was going to take Fuller to the hospital. “He pushes me back down on the ground again and says, ‘No, she can’t talk.’’

Fluker said she leaned into the driver’s side of the vehicle and spoke to Fuller. “I said, ‘Baby girl, you OK?’ She was coughing and she’s moving her head ‘yeah.’’’

She said she then left and didn’t call anyone for help. She went to her mother’s home where she was taken into custody the following morning.

Authorities testified that Fuller was shot in the leg, the arm and the head. The head wound, described as causing a devastating injury to her brain, was the fatal wound.
