It was a quiet Sunday morning in the Seagoville Farms subdivision, the kind of morning where neighbors might have been mowing lawns or heading to church. Then, just before 11:30 a.m. on April 27, 2025, gunfire erupted near the intersection of Fountain Drive and Canterbury Drive, and a 19 year old man named Kaisan Henderson ended up dying in the street.
More than a year later, the case still stands as one of the most unsettling crime stories to come out of Seagoville, not just for the violence itself, but for the strange twist that followed.
What Happened That Morning
According to affiliate CBS Texas, Henderson was walking down the sidewalk in the 2000 block of Canterbury Drive when a black sedan drove past him. The driver turned onto nearby Fountain Drive and stopped in the middle of the street. That driver, later identified by Seagoville police as 51 year old Larry Robertson, got out of the car with a rifle and opened fire.
Henderson, who was also armed, returned gunfire before running away, police said. He did not get far. He was struck down in the street, and a bystander rushed to perform life saving measures until officers arrived and took over. Henderson was rushed to a hospital, where he later died from his injuries.
Robertson tried to flee the scene in his sedan but was quickly stopped by Seagoville officers who were already responding to reports of gunshots. He was the only person inside the vehicle. Officers also found the loaded rifle used in the shooting still inside the car, according to the police report.
A neighbor in the area told CBS affiliate WFAA that the chaos came right into her own home. A stray bullet pierced her daughters bedroom window while the shooting was happening outside. “Everything could have gone a different way, so I’m thankful my babys alive,” she said.
The Alleged Motive
Investigators said the shooting did not happen out of nowhere. According to the arrest affidavit, Robertsons stepdaughter told police that earlier that day she had seen two men loitering near their home in the Seagoville Farms neighborhood on a home surveillance camera. One man knocked on the front door while the other stayed out in the street, and the two appeared to be signaling each other in a way that made her suspicious. Nobody answered the door, and the men eventually left.
She told police she later showed the surveillance footage to Robertson, who got in his car to go look for the men. Camera footage reportedly showed him returning home a short time later, going inside, and coming back out carrying a rifle before driving off again.
“The defendant’s actions, which include seeking out the complainant and his associate while armed with a loaded rifle, are reasonably deemed to be premeditated.”

Seagoville Police Chief Ray Calverley spoke to FOX 4 Dallas Fort Worth about the shooting at the time, saying the outcome never should have happened. “Bad things happen everywhere, but you know this is not the way to solve it. Gun violence never solves anything,” Calverley said.
The Case Takes A Turn
Robertson was booked into the Seagoville holding facility and initially charged with murder. For weeks, the case appeared to be heading toward trial on that charge.
Then, on June 20, 2025, a Dallas County grand jury declined to indict Robertson on the murder charge, according to court records confirmed by WFAA. In legal terms, he was “no billed,” meaning the grand jury did not find enough evidence to move forward with that specific charge.
Robertson was not entirely cleared, however. The Dallas County District Attorneys Office confirmed to WFAA that he was indicted on a separate charge of Unlawful Possession of a Firearm by a Felon, a charge tied to his prior felony history rather than the shooting itself.
FOX 4 also reported a detail that complicates the publics understanding of what happened on Canterbury Drive that morning. While the affidavit confirms that both Robertson and Henderson exchanged gunfire, it does not specify who fired first. Both men appeared to have displayed a weapon at roughly the same time, but investigators noted that no weapon was ever recovered from Henderson at the scene. It remains unclear whether someone else may have been present with Henderson and out of camera view during the shooting.
Why Seagoville Still Remembers
For a small community like Seagoville, a daylight shootout caught on home surveillance camera is not something that fades quickly. It happened on a residential street, in a quiet subdivision, in the middle of a Sunday morning, and a teenager lost his life.
The no bill decision on the murder charge does not erase what happened on Canterbury Drive. It does add a layer of legal complexity to a story that, on its surface, looked straightforward when it first broke. As of this writing, Larry Robertson faces prosecution on the firearm possession charge, while the full circumstances of who fired first, and why two men were allegedly seen at his familys front door that morning, remain part of an investigation that never fully closed the book on what really happened.
