DENVER -- A teacher in a program for gifted and talented students is under investigation for alleged inappropriate behavior in the classroom.

The Jefferson County Sheriff's Office is launching an investigation of teacher Susan Romeo after several parents came forward with allegations of misconduct last month.

A detective with the department's crimes against children unit was given the case Tuesday. Romeo has already been on paid, administrative leave for a month, 7NEWS reported.

Lisabeth Smith pulled her son out of Romeo's gifted class at Coronado Elementary in October.

"(My son) was telling me that he was afraid of her, that he didn't want to go to school, begging me to homeschool him," Smith said.

"I called the licensing board. I called the Board of Education. I called the police again to see what their follow-up was," Smith said.

She's one of several parents to contact 7NEWS with complaints about Romeo's teaching tactics. Smith has also filed a complaint with the Jefferson County Sheriff's Department.

The department confirms it is now investigating Romeo and the school district has been doing its own investigation for more than a month.

"They say they're investigating her, have put her on administrative leave, but they won't tell anyone how they're going about the investigation," Smith said.

The School Board confirms it is looking into accusations of "inappropriate behavior" in the classroom. Now, parents of Romeo's students are being summoned for private meetings on Dec. 1 and Dec. 2 with a risk management team and an attorney for the district as part of the ongoing investigation.

Since 7NEWS' last story, we did receive one phone call from a parent who said the allegations against Romeo are totally false. Our calls to Romeo were not returned.
