Joseph Rene Macias was 19 when he was fatally shot on August 7, 2016, in the 6500 block of Tahoka Boulevard in San Antonio, Texas. The shooting occurred during a drug transaction arranged over Snapchat; Macias and two other teens were meeting with 18-year-old Eric Cavazos, who had posed as a buyer for marijuana. When the deal went wrong, Cavazos opened fire, killing Macias and critically injuring the two other teens.

Cavazos fled on foot but was later located on a Greyhound bus headed for Los Angeles and arrested on a murder warrant in Tulsa, Oklahoma. He also faced aggravated assault with a deadly weapon charges for the injuries to the other teens. Investigators reported that Cavazos had been messaging the teens for about an hour and a half before the meeting and that 911 calls were placed three minutes after the shooting.
