Trinity Dewayn Castleberry Jr., a 21-year-old man from Kenner, Louisiana, died on April 8, 2023, after violence erupted in the 2600 block of Greenwood Drive late that afternoon. Police described a scene shaped by familiarity rather than chance: the people involved knew one another, had been together beforehand, and then, just before evening, their time together turned into a homicide investigation.
Investigators said the fatal shooting happened at about 4:45 p.m.
in that Greenwood Drive area. In the hours after the gunfire, authorities identified Tajh Terrell of Kenner as the suspect. The victim’s name was initially withheld while relatives were notified, but later public notices confirmed Castleberry as the young man who died that day.
Police said Terrell did not disappear after the killing. Instead, he turned up seeking treatment for a gunshot wound he sustained only minutes later and several blocks away—an injury authorities treated as part of the same chain of events that followed the homicide. He was arrested and booked on a second-degree murder charge in connection with Castleberry’s death, while investigators continued working to untangle what happened during the moments between the first shots and the later gunfire that left the suspect wounded.
As the case continued to echo beyond that weekend, reporting tied to court records and police accounts painted a more detailed motive behind the confrontation. Castleberry had been outside when an argument flared over money that was said to be stolen. In that account, the confrontation ended with Castleberry being shot, and then the gunman’s firearm was used against him when another man—Major Robinson of Kenner—allegedly picked it up and fired, wounding Terrell.
Nearly a year later, authorities arrested Robinson in connection with that alleged retaliatory shooting. He was booked on an attempted second-degree murder charge that prosecutors had formally filed days earlier, turning the aftermath of Castleberry’s killing into a second serious criminal case linked to the same burst of violence on April 8, 2023. The publicly available accounts do not provide a final courtroom resolution for either case in the sources reviewed, but they do establish two separate arrests: one for second-degree murder in Castleberry’s death, and another for attempted second-degree murder arising from the alleged shooting of the accused gunman.
