Our previous story:

Prosecuting Attorney Bob McCulloch said Tuesday that Ingerson approached police because he thought he could not be charged in the case.

Donald Ingerson, 67, is charged with one count of rape and one count of second-degree statutory sodomy.

He taught at five or six school districts in St. Louis County beginning in the 1960s and continuing into the 1990s, McCulloch said Tuesday during a news conference at the  in Clayton. McCullouch declined to identify the districts, though he said districts where the suspect worked have been notified and asked to contact police should additional victims come forward.

Patch editors have confirmed the names of the several school districts in St. Louis where Ingerson taught:

• University City Patch from 1976 to 1981.
• Florissant Patch confirmed that . 
• Rockwood School District Chief Communications Officer Kim Cranston  that Ingerson was employed as a science teacher at  in  from 1969-1971. During that time he also served as an assistant coach for football, wrestling, baseball, track and field.
• A KSDK-TV Tweet Tuesday afternoon indicated Ingerson was a former teacher and coach at Ritenour and McCluer schools.

Two victims, both students at the time of the incidents, have been identified so far, though McCulloch said his work in similar cases leads him to think there are others. Ingerson is suspected of having had multiple sexual encounters with both, McCulloch said, the first between September 1974 and January 1976, and the second between Jan. 1, 1995 and Nov. 17, 1996.

McCulloch said he thinks the encounters happened at different locations outside of school grounds.

In early June, Ingerson called the  to say he had something to discuss, McCulloch said. He spoke with investigators.

Ingerson, who lives in Ely, MN, near the Canadian border, arrived in St. Louis on Sunday and repeated statements about the sexual encounters to police on Monday, McCulloch said. At that time, McCulloch said, Ingerson was arrested.

Ingerson did not appear to realize that the statute of limitations had not expired, McCullouch said.

Both victims have been contacted and have been cooperative. Police previously had not heard of either the victims or Ingerson, McCulloch said. 

McCulloch said Ingerson moved to Minnesota sometime after he retired from teaching.

Ingerson is being held in the St. Louis County Jail on a $300,000 cash-only bond. People who think they might have been victims of a sexual crime are asked to call St. Louis County detectives at 314-880-2341.
