The attorney for Ayanna Blue, the emotionally disabled DCPS student who became pregnant during a sexual relationship with a teacher, says four other women have come forward to report that they were assaulted by the same instructor, Robert Weismiller, over a 30-plus-year career in multiple school systems.

In an amended complaint filed Thursday in U.S. District Court, attorney Scott Gilbert said that four former students of Weismiller’s have come forward since Blue’s original lawsuit against the District was filed in September. The women are not mentioned by name in the court papers, but at least one is expected to join Blue at a Thursday afternoon news conference at Gilbert’s New York Ave. office.

Weismiller, who was laid off from his job at the Transition Academy at Shadd during the October 2009 budget crunch, did not return a phone message this morning.

The court filing alleges that Weismiller initiated sexual relationships with two students at Gwynn Park High School in Prince George’s County in 1976, when he was a gym and drivers education teacher. The filing said that Weismiller also assaulted two other former students in 1984 at Fred Lynn Middle School in Prince William County. The alleged misconduct continued into the girls’ ninth-grade year at Woodbridge High School, where he was transferred.

According to the court documents, Weismiller, the Prince William County School Board and several school officials were sued in 1986 in U.S. District Court in Alexandria. As a result, Weismiller was fired, the suit says. Thirteen years later, one of the Prince William students, working as a kindergarten teacher for Fairfax County Public Schools, saw Weismiller at an in-service training day and learned that he was teaching in the school system. The woman said she informed school officials about her lawsuit against Weismiller and was told that he was immediately dismissed, according to the complaint.

Blue seeks unspecified monetary damages against Weismiller, DCPS and former chancellor Michelle A. Rhee. It said Shadd staff suspected in the fall of 2008 that Weismiller, 58 at the time, was having sex with Blue, then 18, in a darkened classroom but did nothing to stop the encounters that led to her pregnancy. It was not until May 2009, when Blue reported to school officials that she was pregnant, that an investigation began, the suit alleges.

Weismiller, who was placed on administrative leave by DCPS, denied having a relationship with Blue. The investigation was inconclusive, and it was only when Rhee laid off more than 200 teachers for budget reasons in October 2009 was Weismiller separated from the school system.

Subsequent paternity tests showed a more than 99 percent probability that Weismiller is the father of Blue’s daughter, now 15 months old.
