SHELBY COUNTY, Tenn. — A 22-year-old woman is charged with first-degree attempted murder after investigators with the Shelby County Sherriff’s Office say she confessed to shooting her mother Tuesday night.

Court records show Alexcia Jones shot her mother, Tanesa Boyd, in her sleep at her home on Orange Tulip Drive around 11:30 p.m. Tuesday, but she wasn’t arrested until Friday night.

When the shooting first happened, people in the upscale neighborhood were shocked. And at the time, investigators weren’t sure who had done it.

But that changed Saturday morning when deputies announced Jones had confessed.

“I couldn’t imagine it,” neighbor Raymond Jones said. “They [are] new neighbors. They [have] been here probably like two or three weeks, and for something like that to happen this soon, just unusual.”

WREG’s Nina Harrelson discovered social media posts that appear to show Jones trying to cover her tracks.

On Facebook, she portrayed a loving relationship with her mom and praised her in several posts just hours before the shooting, saying in one: “My mother, daughter and siblings are all I have. I love them to death.”

In another, Jones posted a photo of her mother and part of a conversation they’d had that day, writing: “Love you too mama. I’ll cook you a big dinner tomorrow.”

Less than five hours later, investigators say Boyd was shot in her sleep.

The next day, Jones made another Facebook post claiming a man went into her mother’s house that night and tried to kill her, and thanking God for stepping in and saving her life.

But court records tell a different story. They show Jones’ mom was sleeping when she heard a “loud bang” and awoke to realize she’d been shot, only to find her daughter standing at the foot of her bed.

The arrest affidavit shows several people were in the house during the shooting, including children.

Investigators say Jones’ siblings told deputies she shot her mother, and Jones later confessed.

Deputies swarmed the house Friday night and arrested Jones. Investigators tell WREG they found the gun in a car outside the home.

“Police officers was down there checking the cars and stuff,” neighbor Christian Ryan said.

Ryan, 12, lives across the street, and spoke to WREG with his parents’ permission. He says he saw Jones and her mom arguing in the garage about a month before the shooting as they were moving into the home.

When asked his thoughts on someone shooting their own mom, he said, “Just sick… It’s just like, the person who birthed you? You just betray them like that?”

WREG went to the home hoping to talk to family, but a woman inside would only say through the door that they had no comment.

According to court records, Boyd was shot “through the arm and shoulder,” but deputies say she’s expected to be OK.

Until now, Jones only had some minor traffic charges on her record. She’s now charged with attempted first-degree murder, tampering with evidence and possession of a firearm during a dangerous felony.

She will be in court Monday.
