Known to vendors at the flea market where his mother had worked for years as “Chente,” the “angelito” was hit in the cross-fire, according to Liliana Jaimes, who started the fundraising campaign to offset the mother’s funeral costs. One day into the campaign, some $9,000 has been raised.
Three teenagers — a 14-year-old girl and 16- and 18-year-old boys — were hospitalized for their injuries, along with a 37-year-old man, the latter of whom has since been released from the hospital, according to Rogers.

Police believe an altercation between “two sets of people” led to the shootout at the flea market, Rogers tells PEOPLE, noting that there were “at least two shooters, maybe three.” Police are not yet clear on the details leading to the gunfire-fueled argument, but do not believe that it was a targeted attack on the flea market.
