An individual in Memphis, Tennessee, has been sentenced to life imprisonment for the brutal killings of his newborn daughter and her mother. These violent acts have been described as “heinous” by authorities.

Brandon Isabelle, 28, received consecutive sentences totaling 51 years for the murders of 27-year-old Danielle Hoyle and their newborn, Kennedy Hoyle, as announced by the Shelby County District Attorney’s Office. Additionally, he was sentenced to 45 more years, divided between convictions for aggravated child neglect and especially aggravated kidnapping. Isabelle had initially pleaded not guilty to the charges.

Prosecutors noted that the latter 22.5-year sentences carried a symbolic weight, representing one year for each hour of Kennedy’s brief life.

The events unfolded on January 30, 2022, when Isabelle was informed that Danielle Hoyle was going into labor. He joined her at the hospital, but during this time, he was also in contact with another woman via text messages.

Isabelle and Hoyle had met at FedEx, where they both worked, and they had a brief sexual relationship resulting in Hoyle getting pregnant, according to state prosecutor Amanda Carpenter. But then Isabelle met someone new, and he was willing to “do anything” to be with her.

This other woman, who was also employed at FedEx, expressed a reluctance to deal with another child or the complications of a “baby mama,” according to Carpenter during the trial. While Isabelle was at the hospital texting this new woman, she was contemplating ending their relationship, but Isabelle was keen on giving it another chance.

“In the early hours of January 31, 2022, amidst these text conversations, baby Kennedy Hoyle was born,” Carpenter continued. Later that morning, Isabelle left the hospital and met with his new girlfriend at Mud Island, a small peninsula in Memphis. They continued their discussions about their relationship, but no resolution was reached.

Hoyle and her baby were released from the hospital the following day — Feb. 1, 2022 — and they returned home to meet their family, according to authorities. Then the mother received word from Isabelle.

He said he wanted to give Hoyle some baby clothes, prosecutors recalled, and so they agreed to meet at a Mapco convenience store in the city, with Kennedy in the backseat of her mother’s car. But Isabelle had an ulterior plan.

He “convinced” Danielle Hoyle to come down another road — one that was “desolate, deserted, [and] dark” — and as she parked her car, he approached, opened the passenger-side door “and fired five shots into Danielle’s car, striking her in the face and the head,” Carpenter stated in court. Isabelle then “dragged” her body and left her “face down in a ditch so dark that all that could be seen were Danielle’s bright pink shoes.”

Isabelle’s plan, as authorities told it, was not finished. He proceeded to take his daughter in her car seat, put her in his own car, and drive away, “leaving Danielle face down … in the muddy rainwater,” Carpenter added. Isabelle went back to his parents’ home, where he lived, and changed his clothes, all while leaving Kennedy — who was not yet even 2 days old — alone in the car.

“He had one more problem to take care of,” Carpenter flatly told the courtroom.

Isabelle returned to his car, drove back to Mud Island — an action captured by “real-time” law enforcement cameras — and stopped at the “old boat ramp” where the mouths of the Wolf and Mississippi rivers meet.

“He took Kennedy from her car seat, grabbed her by the leg, and threw her into the cold, dark water, not realizing that her little baby cap had fallen from her head and lay resting on the riverbank,” Carpenter said.

Isabelle tried to cover his tracks, authorities said. He sent messages to Danielle Hoyle “knowing that she’ll never answer,” and he drove to a nearby Walmart and dumped the car seat there. Still, he focused on his new girlfriend, texting her and going to Walgreens to buy gifts.

A police officer would end up finding Danielle Hoyle’s body after investigating her car being parked on the wrong side of the road. As officials investigated, Isabelle rushed to meet his girlfriend at her residence and immediately told her they needed to leave. The couple were soon after detained.

Police officers searched Isabelle and found blood on his socks that ended up matching Danielle Hoyle’s. Kennedy’s body was not found.

Records showed that Feb. 1 is Isabelle’s birthday, indicating he murdered his daughter and her mother on his 25th birthday.

Isabelle appeared largely stoic as his fate was sealed in a Shelby County courtroom this week, per video recorded by local ABC affiliate WATN.

“We and the family are very pleased with today’s sentence, which reflects the heinous nature of the crimes perpetrated against two cherished members of our community,” Shelby County chief prosecutor Eric Christensen said. “Danielle and Kennedy deserved protection, love, and life. Today’s sentence honors their memory and reinforces our commitment to pursuing justice for the most vulnerable.”
