Ms. Riley was a teacher at Hollyoaks High School who was teaching Zara Morgan's class in April 2000. Zara began causing trouble, mocking the teacher (believing to be out of earshot), but was caught. Ms. Riley later discovered that someone had stolen money out of her bag, and thought it was Zara. She told Mr. Berrington, who confronted Zara, but Zara protested her innocence.
