ALTON — At least two more people have claimed a former middle school teacher here sexually abused them.

In May, the Madison County State's Attorney's Office charged William Ingersoll, 51, with the criminal sexual assault and aggravated criminal sexual abuse of a former student at Alton Middle School.

His bail was set at $250,000, but a family member posted $25,000 in cash on the day of his arrest.

The victim in that case confided in a former high school teacher in the fall of 2018 that she and Ingersoll "engaged sexually," when she was younger than 17. The former high school teacher alerted school district officials, who then alerted authorities.

Ingersoll was a middle school teacher at Alton Middle School from September 1998 through July 2000, according to court documents.

In a press release issued Wednesday, Alton Police Chief Jason Simmons wrote that initially there was "no obvious indication" that there were other victims. But, since news of his arrest broke, two other people have reported inappropriate sexual relations with Ingersoll to Alton police. 

"Today, Alton Police want to remind the public the best way to stop a predator is to break the silence of victims," he wrote. “As I said before, no trusted adult should take advantage of their position to cultivate a sexual relationship, especially with a child.

Alton Police Officer Emily Hejna would not say whether the department is seeking additional charges against Ingersoll for the additional victims, or the time period in which their allegations took place. 

Alton police are asking anyone interested in reporting abuse by Ingersoll or any other suspect can speak to a detective in person at the department, 1700 East Broadway, or call 618-463-3505, extension 634.
