A former Sandridge Elementary District 172 School Board member has been named as someone who may have known about sexual activity in the office of the school's principal.

Steve Brewster, whom Cook County sheriff's police interviewed Monday as part of the ongoing investigation, was identified in a district news release Friday as someone who may have had knowledge of Principal Leroy Coleman's activities.

A DVD recording began to circulate last week showing Coleman and science teacher Janet Lofton having sex in the principal's office. Another woman, identified as teacher's aide and substitute teacher Anjayla Reed, also appears in the recording on a separate occasion being hugged and touched by Coleman.

All three educators resigned their positions last week.

In the news release, the district said Brewster and possibly another member of the board "have known about these allegations for some time and have chosen not to bring the matter to either the superintendent or the whole board."

Brewster -- who turned in his keys to the school and his security alarm code to the superintendent just prior to the start of the School Board's April 4 meeting -- told The Times on Friday that he first learned of the allegations when he saw a story on the news Thursday night.

Calls to Brewster on Monday were not returned.

At the time of his resignation, Brewster was the senior board member, having served since 2001. Brewster, the father of three children in the district, did not submit a letter of resignation and said after a day after the April 4 board meeting that he just wanted to leave the board quietly.

Brewster held one of the four, four-year board seats up for election today. Eight candidates, three of them board incumbents, are seeking election to those spots.

Following Coleman's news conference Monday, his attorney, Raymond G. Wigell, said he had an idea of a motive.

"I think we do know what it is about, but we're hesitant to say that especially with the election being tomorrow," Wigell said Monday.

Rumors of Coleman's affair had reached staff at the school, which educates more than 400 students. According to a Sandridge staff member, who asked not to be named, several people had talked about sex in the principal's office.

But the staff member didn't want to succumb to "rumor mongering."

"I heard it up and down the hall. All year round rumors have been flying around," the staff member said. "It's no big shock. The shock is that it's on tape."
