A Jacksonville jury has convicted 21-year-old Calvin Mapson of manslaughter in connection with a January 17, 2025, parking-lot shooting that killed 40-year-old Trey Carter outside the Circle K on Sunbeam Road. Carter had been at the store following a birthday celebration. Mapson now faces up to 30 years in state prison when sentenced.
Prosecutors' account
According to the State Attorney’s Office, jurors found Mapson guilty of Manslaughter with a Firearm and of Possession of a Firearm by a Juvenile Delinquent found to have committed a felony act. Prosecutors say he now faces a maximum of 30 years in Florida state prison. The case was prosecuted by Assistant State Attorneys Erin Wolfson and Katherina Brown, and sentencing will be set by the Honorable London Kite at a later date. Prosecutors described the verdict as the result of an investigation that linked Mapson to the shooting through witness statements and physical evidence.
Surveillance shows the confrontation
Prosecutors say the Circle K’s surveillance system captured the moments leading up to the deadly encounter. The video shows Carter entering and leaving the store, then exchanging words with Mapson and two other men in the parking lot before shots were fired. The footage reportedly shows Mapson pulling down a mask, revealing a heart-shaped tattoo on his cheek and blue-and-white Nike slides, and then firing five times as Carter falls, according to News4Jax. The same video shows Mapson and another man running from the scene, while Carter was later pronounced dead at a hospital.
How prosecutors tied Mapson to the scene
The State Attorney’s Office says investigators leaned on a mix of incriminating social-media posts, witness testimony and physical evidence to identify Mapson as the gunman. Prosecutors say Mapson was arrested months after the shooting while wearing the same blue-and-white Nike slides seen in the surveillance footage. The State Attorney’s Office credited the Jacksonville Sheriff’s Office with piecing together those details and tying them back to the Circle K on Sunbeam Road. Authorities say officers were called to the store just before 1 a.m. on Jan. 17, 2025 after reports of gunfire.
Next steps
Mapson still faces sentencing, with a potential term of up to 30 years in state prison when the court hands down punishment. A judge will set a date for that hearing. Prosecutors say their case rested on the surveillance video, along with corroborating digital and eyewitness evidence that persuaded jurors to convict, according to News4Jax. The Jacksonville Sheriff’s Office and the State Attorney’s Office continue to list the case as active while sentencing is scheduled.
