Fight Over a Basketball May Have Sparked Deadly Shooting at Downtown San Antonio Park, Records Say
Records say a basketball dispute preceded the Aug. 30, 2026, fatal shooting at Hemisfair in San Antonio. A 23-year-old man was charged with murder.
A dispute involving a basketball preceded a fatal shooting at Hemisfair, the downtown San Antonio park and event space, according to newly released arrest records. Police have since charged a 23-year-old man with murder.
What Happened at Hemisfair
San Antonio police responded to a shooting call just before 5 a.m. on Sunday, August 30, 2026, in the 600 block of Hemisfair Plaza Way, near South Alamo Street. Officers found 35-year-old Jonathan Alderete with a gunshot wound. He was taken to a hospital, where he later died.
Investigators said at the time that Alderete had been in a physical altercation with another man before the shooting, and that the fight appeared to involve a dispute over property. Police did not immediately identify a suspect.
Arrest Records Detail the Basketball Dispute
According to an arrest affidavit, surveillance video from the area showed 23-year-old Isean Hardeman and three others picking up a basketball belonging to Alderete’s group and taking it to a nearby court. Investigators say that encounter escalated into the confrontation in which Alderete was shot. The affidavit does not explain what prompted the fight after they picked up the basketball.
The same surveillance footage helped investigators identify Hardeman as a suspect, according to the affidavit: he fled the scene on an e-scooter, ditched it, ran past a downtown hotel, and boarded a VIA bus.
Investigators later traced Hardeman to a South Side apartment. He was booked into the Bexar County Jail on September 3, 2026, four days after the shooting. He was charged with murder, a first-degree felony, and was being held on $250,000 bond.
The allegations have not been proven in court.
The Investigation
Police have not said what led to the initial dispute over the basketball or why it turned violent. The case remains under investigation by San Antonio police.
Hemisfair, once the site of the 1968 World’s Fair, has been redeveloped in recent years into a downtown park and gathering space with a basketball court, event lawns and civic programming.
