Bonanno found what he suspected to be human cremains in the locket, and a call was put out on social media to attempt to find the owner.
Thomasina Holley-Lewis of Rockland said her cousin saw the Facebook post and texted her to see if the locket Bonanno had found was the one she had lost on the beach two months earlier.
Holley-Lewis recognized her precious item and called Bonanno.
"I called him and said, 'That's my locket,'" she told The Patriot-Ledger newspaper. "My father's watching over me like an angel."
Holley-Lewis said the locket contains the ashes of her father, who died of COVID-19 in November of last year.
Bonanno said his is mailing the locket back to its owner.
"It's about time we have some good news," Bonanno said.
Bonanno said he is still on the hunt for the nurse's missing ring.
