HangupsMusic.com – Jacksonville, FL – Rapper Hakeem Armani Robinson, known professionally as Ksoo, has been handed a significant prison sentence following his admission of guilt in a second murder case. The legal proceedings concluded on Monday, February 23rd, with Ksoo pleading guilty to the second-degree murder of 16-year-old aspiring rapper Adrien "Lil Bibby" Gainer, an incident that occurred in 2019. This plea resulted in a 10-year prison term, which will be followed by a five-year period of supervised probation.
This latest conviction adds a substantial layer to Ksoo’s already severe legal entanglements. It comes on the heels of a prior guilty verdict rendered in July of 2025, where he was found responsible for the 2020 murder of rapper Charles "Lil Buck" McCormick. For that crime, Ksoo was sentenced to life imprisonment without the possibility of parole, a stark testament to the gravity of the offense.
The 2019 incident involving Adrien Gainer took place on February 25th at the New Hope Apartments, formerly recognized as the Hilltop Village Apartments in Jacksonville. Reports indicate that the young rapper was fatally shot at the location. An intensive investigation by law enforcement at the scene uncovered a disturbing amount of evidence, with authorities reportedly recovering approximately 45 shell casings. Following Gainer’s tragic death, Ksoo allegedly engaged in highly publicized social media activity, posting images and videos that appeared to boast about his involvement in the shooting. This behavior further solidified the prosecution’s case and underscored the callous nature of the crime.
The murder of Charles McCormick, which occurred on January 15, 2020, took place in Dames Pointe Plaza on Merrill Road. Investigators have posited that this crime was deeply rooted in an ongoing rap feud, a conflict that escalated following the death of Ksoo’s stepbrother, Willie Addison. Addison had been shot and killed a year prior to McCormick’s murder, immediately after leaving a nightclub. The intertwined nature of these violent acts points to a cycle of retaliatory violence that has had devastating consequences.
The legal ramifications of the McCormick murder have extended beyond Ksoo himself, implicating several members of his family. Ksoo’s father, Abdul Robinson Sr., was also convicted in connection with McCormick’s death. Similarly, Ksoo’s brother, Abdul Robinson Jr., and their cousin, Leroy Whitaker, were also implicated and convicted for their roles in the crime. The sentencing for these individuals varied: Abdul Robinson Sr. received a sentence of time served, effectively releasing him from immediate custody due to the period he had already spent incarcerated. Abdul Robinson Jr. was sentenced to 12 years in prison, while Leroy Whitaker received the most severe penalty, a life sentence, mirroring the fate of Ksoo for the McCormick case.
The cumulative sentences faced by Ksoo underscore the severe consequences of violent crime within the music industry and beyond. The legal system has imposed significant penalties, reflecting the gravity of the offenses and the impact on the victims and their families. The ongoing legal battles and convictions highlight a tragic pattern of violence that has deeply affected the hip-hop community, particularly in the Jacksonville area.
The original report by First Coast News detailed the discovery of the shell casings and the alleged social media activity by Ksoo. This additional 10-year sentence, to be served consecutively with his life sentence, means Ksoo will spend a considerable portion of his life incarcerated, a stark reality for the young artist whose career was tragically overshadowed by criminal activity. The case serves as a somber reminder of the perils that can accompany escalating disputes and the irreversible damage caused by violence.
