Police found Ashley Caldera's body in Northgate Park on Saturday night, following reports of gunfire. Authorities said someone opened fire on Caldera and a group of friends.
Sunday night, loved ones returned to the park to remember the teenager.
"I want the person that did this put in jail, because they took my baby's life and I wouldn't want anybody to go through this," said Caldera's mother, Lorraine Valdez.
Police said the shooters were not acquainted with the group. The motive was under investigation.
Witnesses said the suspects were male. No arrests have been made.
