Jaws Wiki

Charlene is the girlfriend of Shelby Overman in Jaws 3.

When Shelby is killed by the shark, Charlene assumes that he has left because he hasn't returned to her home. She throws out his things and informs Mike Brody that she is kicking him out if she shows up later.

Although she was angry with his absence, she claims that she doesn't mean him any harm.

It's unknown whether or not she was informed of Shelby's murder.
