A white former University of Hartford student accused of smearing body fluids on her black roommate's belongings has pleaded not guilty to charges of criminal mischief and breach of peace.

Prosecutors did not file additional charges Monday against Brianna Brochu, 18, of Harwinton.

Representatives of the state NAACP and other civil rights advocates protested again in front of the courthouse, asking the state to add a hate crimes charge.

According to police, Brochu wrote on Instagram in October about rubbing used tampons on her roommate's backpack and putting her roommate's toothbrush "where the sun doesn't shine." Her roommate says she developed throat pain.

Prosecutors say they're still investigating. The case has been continued until Jan. 29.

Brochu left the courthouse without commenting. Her lawyer has said her actions were not racially motivated.
