A San Antonio man has been sentenced to spend the rest of his life behind bars without the possibility of parole following his capital murder conviction in the fatal 2019 jailhouse beating of his cellmate. A Bexar County jury delivered the guilty verdict against 39-year-old Shandrick Van Anthony Buckley after days of courtroom proceedings detailing the violent physical encounter.
The trial took place in the 226th Judicial District courtroom, where jurors received the case shortly before 4 p.m. on Tuesday. As deliberations stretched past 6 p.m., state District Judge Benjamin Robertson instructed court deputies to begin preparations to sequester the panel overnight. However, the jury signaled just before 9 p.m. that they had reached a unanimous decision. Because the Bexar County District Attorney’s Office chose not to pursue the death penalty, Judge Robertson immediately handed down the mandatory term of life imprisonment without parole.
The fatal encounter occurred on May 30, 2019, inside the Bexar County jail, where Buckley had been placed in cell C23 alongside 29-year-old Alexander Wise. Officers later discovered Wise lying unresponsive near the entrance of the locked cell, surrounded by a pool of blood, before medical personnel determined he had died at the facility.
At the time of the fatal assault, Buckley was already incarcerated while awaiting trial on a separate murder indictment that accused him of stomping another man to death behind Haven for Hope in 2017. Wise, by contrast, had been booked into the county facility on nonviolent charges that included credit card fraud and drug-related offenses.
During closing arguments, Bexar County Assistant District Attorneys Raul Jordan and Cassandra Rosales outlined the state's case, telling jurors that Buckley ambushed Wise without provocation and beat and stomped the younger man to a pulp. While prosecutors acknowledged that they did not present a specific motive for the attack, they repeatedly directed the jury to review the physical evidence, including graphic crime scene photographs and body camera footage recorded by responding detention personnel.
Witness testimony during the trial revealed that jail staff initially uncovered the assault during a routine security check of the housing unit. Detention officers noticed blood flowing outward from beneath the door of cell C23. Upon stepping inside the room, responders discovered Wise completely incapacitated, observing heavy blood spatter reaching as high as waist-level along the interior walls.
Following the deadly incident, Buckley sat for an interview with jail investigators and acknowledged carrying out a physical assault on his cellmate. When questioned by detectives about the precise physical mechanics of how he struck Wise on the ground, Buckley admitted to delivering multiple punches and described stamping down with his foot as though he were attempting to extinguish a fire.
Medical professionals offered stark details regarding the catastrophic extent of the trauma inflicted on Wise during the cellhouse attack. Howard Huber, a physician assistant who attempted to administer life-saving measures to Wise, testified that the victim suffered a severe Le Fort fracture. Huber explained that this midfacial trauma had completely detached the upper jaw and facial structure from the base of the skull, resulting in a condition medically described as a "floating face."
The Bexar County medical examiner's office formally determined that Wise died as a direct result of blunt force injuries sustained to his head and neck. In his presentation to the jury, prosecutor Jordan displayed official medical diagrams highlighting that Buckley exhibited no defensive wounds, cuts, or bruises after the lethal encounter.
Jordan pressed the significance of this physical disparity during his final remarks, asking the panel how it was possible for Buckley to escape the altercation completely unscathed if it had been a mutual struggle. The prosecutor argued that with Wise's blood covering Buckley’s footwear, pants, and clothing, the physical evidence demonstrated that Buckley knocked Wise to the floor and stomped him to death.
Buckley’s defense team, led by attorneys Cleophus Marshall and Cornelius Cox, challenged the prosecution's narrative by emphasizing that only two people were present inside the locked cell. The defense argued that the state could not establish beyond a reasonable doubt that Buckley committed capital murder, proposing instead that Buckley might have been acting in self-defense against Wise.
Marshall also raised serious questions regarding jail administration decisions, noting that authorities had identified Wise as a member of the Aryan Brotherhood, a neo-Nazi prison gang. The defense attorney questioned why jail staff would house a documented gang member in the same confined cell as Buckley, who is Black, especially given the volatile racial tensions inherent in correctional settings.
To support the self-defense theory, Marshall pointed to evidence that Wise had been involved in an altercation with another incarcerated individual immediately prior to being transferred into Buckley’s cell. Furthermore, Marshall emphasized that Buckley had accumulated a record of 23 fights during his incarceration, suggesting that Buckley reasonably anticipated violence and expected an altercation with Wise.
The defense further argued that the conditions inside the cell indicated irregular circumstances, pointing out to jurors that crime scene photographs showed no mattress on the bunk designated for Wise. Marshall implied that the placement was part of an illicit "fight club" culture within the Bexar County jail, citing earlier trial testimony from a former county detective who admitted that inmates had previously been allowed to fight one another.
Throughout the legal proceedings, defense counsel repeatedly noted Buckley’s complex history regarding mental competency, explaining that he had moved in and out of competency to stand trial over the years following the 2019 killing. While Buckley initially entered a formal plea of not guilty by reason of insanity, the presiding judge instructed the jury that they were barred from factoring that specific defense into their deliberations, ultimately resulting in the capital murder conviction and life sentence.
