Investigators say the accused gunman told officers the victim did not threaten him or appear to be armed.
TYLER, Texas — A Friday evening traffic dispute in Tyler ended with a former Marine dead beside his family’s Tesla and a 23-year-old pickup driver in jail on a murder charge after police said the evidence did not support a claim of self-defense.
Authorities identified the dead man as Trevor Julian, 29, of Whitehouse, and the suspect as Dayton Alexander Morgan, 23. The shooting happened at one of Tyler’s main intersections during the evening commute, drawing multiple 911 calls and leaving drivers stalled behind a police closure that lasted for hours. The stakes widened almost immediately because Julian’s wife was driving the Tesla and the couple’s children were in the back seat. Police said Morgan stayed at the scene and spoke with investigators, but arrest records later described a version of events that detectives said failed to justify deadly force.
According to police, both vehicles were stopped at a red light at Grande Boulevard and Paluxy Drive around 5 p.m. on Feb. 13. Julian was in the passenger seat of the Tesla. Morgan was in a pickup behind it. Investigators said tension built after Morgan’s truck stopped very close to the Tesla. Morgan later told officers that the Tesla had made an abrupt stop and that his truck ended up nearer to the rear of the car than he wanted. Julian then got out and walked back toward the driver’s side of the pickup, police said. Words were exchanged. Morgan told investigators that Julian shouted for him to move back. Morgan answered with his own profanity, and the argument continued at the truck door. He then retrieved a handgun from inside the truck, racked the slide and fired through the driver’s side window, according to police accounts summarized in local reporting.
Officers responding to the intersection found Julian on the roadway with bystanders trying to save him. He had been shot in the neck, according to police. He was taken to a local hospital, where he died. Investigators said Morgan admitted firing the weapon and was the only known shooter. What made the affidavit notable was not just Morgan’s description of the argument, but what he said did not happen. Police wrote that Morgan told them Julian never made verbal threats and did not seem to have a gun. Detectives then stated that the evidence gathered in the case did not support a self-defense claim. That conclusion became the key dividing line in the public understanding of the case. In Texas, public debate often turns quickly to whether a person feared imminent harm. Here, police said their investigation did not establish that kind of threat.
Julian’s death also carried a deep local and personal dimension. He was identified in East Texas news coverage as a 2015 graduate of Carthage High School and a U.S. Marine who had served in Okinawa, Japan, as an automotive maintenance technician. Old family footage resurfaced after his death, including a message in which his mother said she was proud of his character and service. Those details helped explain why the case landed with unusual force in the region. It was not only a homicide at a traffic light. It was the killing of a young veteran in front of the people closest to him. Tyler police spokesperson Andy Erbaugh called it a horrific incident, and the language matched the sequence described by witnesses and officers: daylight traffic, a red light, a brief confrontation and then a fatal shot with children still inside the nearby car.
The case now moves into the slower, less visible stages of criminal court. Morgan was booked into the Smith County Jail on a murder charge and held on a $1 million bond. Public court information cited in local reporting did not show a hearing date in the immediate days after the arrest. Prosecutors are expected to keep assembling witness statements, scene evidence and any video that may exist from the area. The defense, in turn, can press questions about distance, timing, the truck door position and what Morgan believed in the seconds before he fired. But based on the records available so far, police are standing by the central allegation that this was not a legally justified shooting. That position is likely to shape charging decisions, pretrial filings and any future courtroom arguments over intent and perceived danger.
The scene itself helps explain why the case has stayed in public view. Grande Boulevard and Paluxy Drive is not a remote road or a deserted frontage lane. It is a heavily traveled Tyler corridor where many residents pass at the end of the workday. Police closed both directions of traffic while investigators processed the shooting site, and the road did not fully reopen until later that night. For drivers caught behind the tape, the event was an abrupt break in an ordinary commute. For Julian’s family, it was far worse. A routine trip ended in a killing that local readers, veterans and neighbors have struggled to square with how quickly it unfolded. The public facts remain narrow, but the consequence is stark: one man is dead, another is jailed, and a family now sits at the center of a criminal case that began with a few feet of roadway space.
As of the latest public accounts, the investigation remained open and Morgan was still being held in Smith County. The next step is expected to be a first court setting or additional release of records that further explain the timeline and the evidence behind the murder charge.
