Stewart found a knotted bag and took it home. Inside it, she found a silver necklace and two charms, the television station reported.
Stewart said that along with a small canister of ashes there were charms said “son” and “I still need you close to me."
"I didn't want to leave it," Stewart told KNXV "I'm a mom … I would be devastated."
Stewart said she is keeping the necklace and is hoping to find the owner, the television station reported. Anyone with information is asked to email KNXV at email@example.com.
