Knox Brewer of Johns Island took up “magnet fishing” and began hunting for metal objects underwater as a way to pass time during the coronavirus pandemic, his family members told WCIV-TV this week.

The boy was out with his family at Whitney Lake this month when the magnet attached to his line stuck to something heavy in the mud below, the news outlet reported.

With the help of a bystander, Knox pulled in and pried open what turned out to be a waterlogged lockbox containing debris-covered jewelry and credit cards as well as a checkbook, according to a video of the discovery.

“I knew the right thing to do was go ahead and call the local authorities, get them involved and try to solve this mystery,” the child’s father, Jonathan Brewer, told the outlet.

Authorities determined the sunken safe belonged to a woman who lived across the street from the lake.

She said it had been stolen from her home eight years ago, the outlet reported.

While most of the expensive items had been taken, the find still turned out to be a valuable catch, according to the Brewers.

They said they were able to reunite her with charms from an old bracelet.

“The first thing that she did was just kneel down, hug Knox and thanked him and thanked him for bringing that closure to her,” Jonathan Brewer said.
