Aaron Bushnell was a volunteer who helped the homeless.
"Bushnell had volunteered with the San Antonio Care Collective to offer support to the city's unhoused population, Lupe Barboza of the Care Collective told Texas Public Radio.
Barboza said Bushnell developed deep friendships with people living in encampments and would regularly purchase blankets, sweaters and snacks from a store on base to give out."
