Inside a luxury apartment parking garage in Florida, a hairstylist was fatally stabbed by a knife-wielding attacker. The brute bragged to the police about the killing, stating that he had “killed someone and walked away.”

Hailey Hosford had stepped out of a rental car at the Retreat at Sawgrass Village in Sunrise, Fla., when she spotted an armed Jackson Sagesse begin to approach her just after 1:30 a.m. on May 28.

Hosford, 27, attempted to escape by jumping back into the rear passenger side of the car, but the 280-pound thug allegedly ripped open the door, according to an arrest affidavit viewed by The Post.

A physical altercation broke out between Hosford and Sagesse and the suspect was captured on security camera making a repeated stabbing motion into the vehicle, police said.

Sagesse got out of the car and was confronted by Hosford’s male friend, who had returned from picking up some items from his apartment.

The two men got into a “violent confrontation” before Sagesse stabbed the man, who was not identified, in the throat.

The wounded victim managed to escape from the maniac and called the police.

Sagesse allegedly returned to the car and attempted to leave in the vehicle, but failed to move it.

He was seen searching the area for evidence before leaving the garage.

Police found Hosford, who was unresponsive, inside the car. She had suffered multiple stab wounds to her neck and throat and was pronounced dead at 2:01 a.m.

Hosford’s friend suffered a puncture wound to the throat.

Hosford owned her own beauty salon in Fort Lauderdale and was a teacher and ambassador for a yoga and retreat company.

She was remembered as a “force to be reckoned with.”

“I know she was a fighter; I believe she fought, and I believe she was scared,” Hosford’s friend Aubrey Rosebrock told WSVN.

Rosebrock recalled the last message his best friend ever sent him.

“Her very last message to me was, ‘I just wanted to tell you that the sun is shining, the sky is blue, the water is turquoise, and that I love you much, and that you mean the world to me,’ and that was the very last thing she said,” he told the outlet. “She’s not a Jane Doe, and I want the world to know what her name is and who she was. There’s evil, and there’s good, and we lost the good. The good lost.”

Workers at the Retreat recognized Sagesse from the surveillance video and pointed police to his home at the complex he shared with his mother.

Sagesse was taken into custody by police wearing the same clothing as the suspect on the video, police said.

Detectives discovered blood smeared on the apartment’s rear door and two missing knives from the knife block in the kitchen, matching the description of the suspected murder weapon.

After his arrest, Sagesse admitted to the brutal stabbings.

“I just killed someone and walked away,” he told police after his Miranda rights were read, the affidavit states.

Sagesse, who gave inconsistent answers, claimed he was on his way to the gym when he noticed the car in the parking garage with its lights on.

He said he attempted to call 911 about the vehicle but didn’t have his phone, so he returned to his apartment and allegedly grabbed a kitchen knife he used as personal protection.

Sagesse said he was “murdering for self-defense” but failed to give an exact threat.

Police charged him with premeditated murder and attempted first-degree murder.

He is being held without Bond at the Broward County Jail.
