On Saturday, police told reporters they had launched the investigation in early March after the parent of one of the alleged victims contacted a staff member at Vernon Hills High School, where Beard is a part-time coach, reports CBS Chicago. Beard allegedly had sexual relations with the students between December 2016 and Feb. 18.

A judge on Tuesday refused attorney Barry Sheppard's request to reduce Beard's bail to $250,000.

Sheppard described Beard as being "very distraught."

"This is a person who's lived a law-abiding life, who's been a good coach, and led an exemplary life thus far. We're hopeful to restore her to her pretrial freedom soon," he said.
