RAPID CITY, S.D. — A Rapid City school teacher accused of abusing a disabled student pleaded not guilty on Monday morning.

Shea Lindsey, a 25-year-old who taught special education at East Middle School, was soft-spoken and straight-faced during her brief arraignment Aug. 12 at the Pennington County Courthouse. She has remained out of jail on bond since her arrest in May.

Lindsey faces a maximum sentence of 10 years in prison and a fine of $20,000 if convicted of child abuse.

Details about the alleged abuse have been scarce and no new ones came to light at Monday's hearing. Paul Andrews, Lindsey's defense lawyer, declined to discuss the case with the media, saying it would be "ill-advised" to do so at this time. Pennington County prosecutors have previously declined to comment as well. Police reports, meanwhile, are sealed.

The district placed her on administrative leave in May soon after the allegations against her surfaced, according to a news release from the Pennington County Sheriff's Office.
