Luis Fernando Carranza, a 24-year-old Hispanic/Latino man from Denton, Texas, was killed during a confrontation in the parking lot of a QuikTrip in the 300 block of West Eagle Drive. Although the date originally associated with the case was September 29, 2025, the official Denton Police Department account places the shooting and Carranza’s death in the early morning hours of Sunday, September 28. At 12:58 a.m., a 911 caller reported that a fight was taking place in the parking lot and then heard gunfire while speaking with dispatchers. Responding officers found Carranza suffering from an apparent gunshot wound, rendered aid, and had him transported to a hospital, where he was pronounced dead. Medical-examiner information subsequently reported in local news identified the cause of death as a gunshot wound to the chest.
Investigators said the encounter began with an argument over a right-of-way issue in the parking lot.
Police determined that Carranza and a friend had no prior relationship with the two people later identified as suspects, Alfred Jackson Jr. of Pattison, Mississippi, and Olivia Guster of Port Gibson, Mississippi. According to the police investigation, the verbal disagreement escalated into a physical fight. The department’s initial account said Jackson struck Carranza’s friend with a shovel while Guster assaulted both Carranza and his friend. Investigators further alleged that Jackson produced a firearm, shot Carranza, and then pointed the weapon at Carranza’s friend. Court-document reporting based on surveillance footage described the sequence somewhat differently, stating that Jackson appeared to knock Carranza to the ground with the shovel before pulling a gun and shooting him in the chest. Both accounts identify Jackson as the alleged shooter.
After the shooting, police said Jackson and Guster left the QuikTrip in a vehicle driven by Guster. Witnesses supplied officers with information about the fleeing vehicle, and police located and stopped it a short time later in the 1400 block of West University Drive. Guster remained with the vehicle and was detained. Jackson ran from officers during the traffic stop, but police apprehended him shortly afterward and initially arrested him for evading arrest or detention. As detectives continued investigating the shooting, they obtained warrants accusing Jackson of murder and aggravated assault with a deadly weapon. Detectives also obtained a murder warrant for Guster. Both were first taken to the City of Denton Jail before being transferred into Denton County custody.
Denton County Jail records subsequently reflected serious criminal allegations against both suspects. Jackson was held on the murder case as well as aggravated assault with a deadly weapon and evading arrest or detention. Guster was held on a murder charge. Reporting that relied on the Denton County Jail records listed Jackson’s total bond at $2.11 million and Guster’s bond at $1 million. The two Denton County jail-record links associated with the case correspond to the defendants’ incarceration records, although the county’s Public Access pages currently enter a redirect loop when accessed through this research environment. Independent reporting that specifically cited Denton County Jail records confirmed the charges and bond figures.
Guster later disputed the implication that she willingly participated in a murder. In a jailhouse telephone interview reported from court documents and local television coverage, she said she had gotten out of the vehicle intending to break up the confrontation and claimed that she was struck in the face during the altercation. Her mother likewise publicly maintained that Guster had acted defensively rather than initiating the violence. Those statements represented the defense side of the story and did not change the police allegations: investigators accused Guster of assaulting Carranza and his friend during the fight and then driving Jackson away from the scene after Carranza was shot.
The investigation therefore resulted in two murder arrests, with Jackson additionally accused of threatening Carranza’s surviving friend with the firearm and of fleeing from police. The available online reporting reviewed through August 20, 2026, does not establish that either Jackson or Guster has been convicted, acquitted, sentenced, or otherwise reached a final disposition in the homicide case. No reliable online source located in this search documented a completed trial or conviction. Accordingly, Jackson and Guster should be described as defendants or suspects accused in Carranza’s killing rather than as convicted offenders. The public record available online most clearly establishes the arrests, the filed charges, the substantial bonds, and the police allegation that a seemingly ordinary dispute over right-of-way escalated within minutes into a physical confrontation and the fatal shooting of Carranza.
