Alonzo Cantu Jr., a 19-year-old Hispanic male, died April 9, 2019, after being shot during a shootout on the East Side of San Antonio in the 1100 block of Virginia Boulevard. San Antonio Police found him and a 15-year-old, Jose Barrera III, on the street and transported both to San Antonio Military Medical Center in critical condition; Alonzo died the same day and Jose Barrera III died April 13, 2019.

The exchange of gunfire involved multiple individuals. Two men, Fernando Javier Gonzalez III, 23, and Jose Recarrdo Serrano, 18, were arrested and charged with capital murder in connection with the deaths and were also indicted on aggravated assault and tampering with evidence. Investigators say a third gunman may have been involved and remains at large.

Alonzo had been arrested in December 2018 on suspicion of murder in the fatal September 22, 2018, shooting of 15-year-old Sonny Vidales; he was released on bond in January 2019 and was indicted on that murder charge days before his own death, after which the case against him was dismissed.

Did anyone on the East Side see the shooting or recognize the third gunman involved?
