Five weeks after Waterville Senior High School Principal Don Reiter was placed on paid administrative leave for a reason that is being kept secret, a report of the police investigation of the case is in the hands of the district attorney’s office.

Kennebec County District Attorney Maeghan Maloney said she expects her office will have completed at least an initial review of the case by the end of next week.

“I know this case is one that the public is interested in and it needs to have a quick turnaround, so we’re going to try to do that,” Maloney said Tuesday.

Police Chief Joseph Massey said Tuesday that a detective from his department forwarded his report on the case to the district attorney Sept. 25.

“The DA will go over the case, and they have some options,” Massey said. “They can say, yes, it supports criminal changes, or no, it doesn’t, or we’d like additional information.”

Massey said he has fielded calls from people wanting to know the status of the investigation.

“I think everyone is anxious to find out exactly what’s happening with our investigation and, of course, the school investigation,” he said.

Reiter was placed on paid administrative leave Sept. 1 by Eric Haley, superintendent of Alternative Organizational Structure 92, which includes Waterville, Winslow and Vassalboro schools.

Haley reported the case to police, who conducted an investigation, and Haley and Assistant Superintendent Peter Thiboutot conducted a separate, internal school-based investigation. Neither Haley nor Massey would reveal what the investigation is about, but Reiter’s attorney, Gregg Frame, of Portland, indicated Sept. 8 that it has to do with allegations by another person.
